NEW QUESTION # 29
A CGNAT pool shows repeated alloc-failures and increasing free-failures . Which troubleshooting approach is most appropriate?
- A. Reboot Versa Analytics because allocation counters are stored only there.
- B. Troubleshoot only OSPF neighbors in the LAN VR.
- C. Inspect CGNAT pool statistics and then verify CGNAT state in the vsmd daemon.
- D. Ignore the counters because CGNAT does not track allocation state.
Answer: C
Explanation:
The correct answer is A . Versa CGNAT troubleshooting documentation provides a clear workflow for CGNAT issues. It first describes how to view CGNAT summary information using show orgs org-services < org > cgnat summary. It then shows how to view per-pool statistics using show orgs org-services < org > cgnat pools < pool-name > statistics. The sample output includes counters such as bindings-allocated , bindings-freed , alloc-failures , free-failures , out-of-address-errors , and out-of-ports-errors .
If these counters indicate failures, the next step is to inspect CGNAT state inside the vsmd daemon, including tenant state, ACL matching, pools, bindings, and source-port resources. This helps determine whether the issue is pool exhaustion, rule mismatch, resource allocation failure, or stale runtime state.
OSPF may affect routing but does not explain CGNAT allocation counters. Analytics may store logs but is not the dataplane authority for NAT allocation. Rebooting Analytics would not resolve CGNAT resource programming on the VOS device.
NEW QUESTION # 30
What are three roles that VOS performs? (Choose three.)
- A. SD-Branch
- B. Controller
- C. Log Collector
- D. Zookeeper Arbiter Node
- E. uCPE Platform
Answer: A,B,E
Explanation:
The correct answers are A, B, and E . Versa Operating System, or VOS , is the software platform used for Versa SD-WAN branch and headend functions. Versa troubleshooting documentation explicitly refers to common runtime state across SD-WAN Controller, branch, and hub devices , confirming that VOS is used for Controller and branch-style SD-WAN roles. Versa monitoring documentation also lists SD-WAN branches, SD-WAN Controller nodes, SD-WAN hubs, vCPEs, and uCPEs as assets that are monitored and managed in Versa Director, which aligns with VOS being used as a branch/edge and controller platform.
VOS can also act as a uCPE platform . Versa documentation includes procedures to configure uCPE on a VOS device, showing that VOS can host or support uCPE deployment use cases.
The originally provided answer A, C, D is not correct. A Log Collector or log forwarder function belongs to the Versa Analytics architecture, not the VOS branch role; Versa's design guide states that the log forwarder is part of the Versa Analytics node or can run as a standalone log-forwarder server.
A Zookeeper arbiter is also not a standard VOS SD-WAN device role in this context.
NEW QUESTION # 31
You want to test a WAN circuit in a way that more closely simulates a single SCP or FTP file transfer. Which method should you use?
- A. Run show interfaces brief repeatedly during business hours.
- B. Run the internet speed test from Versa Director with default settings.
- C. Use only the SD-WAN SLA monitor latency value.
- D. Run the internet speed test from the VOS CLI using the single-session option.
Answer: D
Explanation:
The correct answer is B . Versa documentation for internet speed tests explains that when you run an internet speed test from a Director node, it creates approximately 200 sessions . This is useful for measuring aggregate throughput, but it does not represent the behavior of a single application flow. The same documentation states that you can run a speed test with a single session from the device CLI, and that this is useful for simulating file transfer rates when using SCP or FTP .
Therefore, when the goal is to understand how a single file transfer behaves, the CLI-based single-session test is the best option. A default Director-based test may produce higher aggregate results because multiple sessions can use parallelism and better fill the pipe.
show interfaces brief is useful for interface status and addressing, but it does not measure file-transfer throughput. SLA latency is useful for path-quality monitoring, but latency alone does not show single- session TCP throughput.
NEW QUESTION # 32
A Director administrator opens the Monitor tab for a provider organization and wants to see the number of tenants, SD-WAN branches, Controllers, hubs, Director nodes, and Analytics nodes. Which pane provides this information?
- A. Uptime
- B. High Availability
- C. Asset Inventory
- D. Package Information
Answer: C
Explanation:
The correct answer is A . Versa monitoring documentation states that when an administrator selects a provider organization in Director and opens the Summary tab, the screen displays several panes. The Asset Inventory pane displays the number of tenants, SD-WAN branches, SD-WAN Controller nodes, vCPEs, SD-WAN hubs, uCPEs, Director nodes, and Analytics nodes in the organization.
This pane is useful for quickly validating the managed estate and confirming whether expected infrastructure objects exist under the provider organization. It also provides a Details button to display asset information in tabular format, which can help during audits or operational checks.
Package Information shows software package details for the selected node, not organization-wide inventory. Uptime shows how long a node and its software have been running. High Availability shows Director HA information. These panes are useful, but they do not provide the organization-level asset count requested in the question.
NEW QUESTION # 33
You need to quickly check interface administrative status, operational status, tenant ID, VRF, MAC address, and IP address on a VOS device. Which command should you use?
- A. show interfaces brief
- B. show system storage
- C. show coredumps
- D. show system package-info
Answer: A
Explanation:
The correct answer is A . Versa's handy CLI command reference lists show interfaces brief as the command used to view a list of interfaces along with their MAC addresses, operational and administrative status, tenant ID, VRF, and IP addresses. This is one of the first commands administrators run when validating device bring- up, staging interface assignment, WAN/LAN mapping, or whether a template applied interface addressing as expected.
For deeper interface troubleshooting, show interfaces detail provides additional information such as interface index, host interface, MTU, speed and duplex settings, RX/TX errors, and bridge information. However, for a quick overview of state and addressing across interfaces, show interfaces brief is the correct choice.
show system package-info identifies the running VOS software package. show system storage reports system storage resources. show coredumps shows generated core files. These are valuable operational commands, but they do not provide the requested interface status and addressing summary.
NEW QUESTION # 34
Examine the CLI output in the exhibit.
You are reviewing the OSPF adjacency on a VOS CPE, and the output is shown in the exhibit. In this scenario, what is the probable cause of the OSPF adjacency issue?
- A. There is an OSPF area mismatch between the peers.
- B. There is a filter configured on the peer that is dropping 224.0.0.5 traffic.
- C. There is an interface MTU mismatch between the OSPF peers.
- D. There is no bidirectional communication between the OSPF peers.
Answer: C
Explanation:
The correct answer is B . The exhibit shows the OSPF neighbor in the exst state, which means Exchange Start . Versa documentation lists the OSPF neighbor state codes and identifies exst as "exchange start," followed by exchange, loading, and full. In normal OSPF adjacency formation, neighbors progress through initialization and two-way communication before they negotiate database exchange. If the neighbor becomes stuck in ExStart or Exchange, a common and highly probable cause is an MTU mismatch between the two OSPF peers. During database description packet negotiation, the peers must agree on parameters that allow LSDB exchange; an MTU mismatch can prevent the adjacency from advancing to Full.
Option A is less likely because an area mismatch usually prevents the neighbor relationship from forming correctly rather than leaving it stuck in ExStart. Option C is also incorrect because the neighbor has already progressed beyond early states, which indicates that bidirectional communication has occurred. Option D is not the best answer because dropping OSPF multicast 224.0.0.5 would typically prevent discovery or keep the adjacency in an earlier state, not specifically in ExStart.
Therefore, the probable cause is an interface MTU mismatch.
NEW QUESTION # 35
An SD-WAN branch is deployed behind a NAT device. In the VSM local-tunnel-site output, which field or flag indicates that a WAN link is behind NAT?
- A. WAN lcl link behind NAT or BN flag
- B. Neighbour site type only
- C. WAN lcl vrf-id only
- D. Tenant ID only
Answer: A
Explanation:
The correct answer is A . Versa SD-WAN data-path troubleshooting documentation shows the VSM local- tunnel-site output and includes a legend in which BN means Behind NAT . In the WAN local link details, the output also displays a field named WAN lcl link behind NAT , with values such as 1 or 0, and link flags including [ BN CT PT SLA-P ] when the WAN link is behind NAT.
This information is important because NAT status affects how SD-WAN tunnel endpoints are discovered and how public and private transport addresses are represented. The same output includes both public and private WAN link addresses, making it useful for troubleshooting sites behind NAT, stale tunnel endpoints, or incorrect public-address learning.
WAN lcl vrf-id identifies the local transport routing instance ID, not NAT status. Tenant ID identifies the tenant context. Neighbour site type identifies whether the remote endpoint is a Controller, hub, or SD-WAN site. None of those fields specifically confirms whether the local WAN transport is behind NAT.
NEW QUESTION # 36
Examine the exhibit below.
You are deploying Versa Secure SD-WAN and require high availability for the Versa Directors. You configured the Versa Director high availability parameters shown in the exhibit. With the parameters shown, which two statements are true? (Choose two.)
- A. The primary Director will automatically take over mastership once it comes back online.
- B. The administrator must manually set the primary Director as active once it comes back online.
- C. The backup Director will automatically take over mastership if the primary Director fails.
- D. The administrator must manually initiate the failover to the backup Director.
Answer: B,C
Explanation:
Comprehensive and Detailed 150 to 250 words of Explanation From Versa Networks SDWAN Topics:
The correct answers are B and D . In the exhibit, Enable Auto Switchover is not selected. However, the Failover Timeout value is configured as 300 seconds . Versa Director HA documentation states that the Failover Timeout is the timeout period before the standby Director node can promote itself to become the active Director node. Therefore, if the active or primary Director fails, the backup Director can automatically assume the active role after the failover condition and timeout are met.
The important distinction is that Auto Switchover controls revertive behavior after recovery, not the initial standby takeover during failure. Versa documentation explains that Director HA is non-revertive by default.
This means that when the designated master or primary Director comes back online after recovery, it is not automatically promoted back to active unless automatic switchover is enabled. To make the designated active Director automatically reclaim the active state after recovery, Enable Auto Switchover must be selected and the Auto Switchover Timeout must expire.
NEW QUESTION # 37
You are asked to ensure symmetric traffic flows between two SD-WAN branches. Which feature should be enabled to achieve this objective?
- A. Packet Striping
- B. Symmetric Routing
- C. Symmetric Forwarding
- D. Equal-Cost Multipath
Answer: C
Explanation:
Symmetric Forwarding is the correct Versa SD-WAN feature for ensuring that return traffic between SD- WAN branches follows the same SD-WAN path on which the forward traffic was received. Versa documentation for SD-WAN traffic steering describes Symmetric forwarding as the option that specifies the path for reverse-direction traffic, meaning whether traffic returning from the destination branch to the originating branch should be sent on the same path on which it arrived. It further states that enabling symmetric traffic forwarding determines the reverse path for traffic returning from the destination branch to the originating branch.
This is different from Symmetric Routing, which is a routing design goal or behavior, not the Versa SD- WAN forwarding-profile feature named in the product documentation. Equal-Cost Multipath can distribute flows across equal-cost routes, but it does not specifically guarantee that both directions of the same SD-WAN session use the same path. Packet Striping is used to split or distribute packets across multiple links for performance, not to enforce bidirectional path symmetry. Therefore, the verified Versa feature to enable is Symmetric Forwarding.
NEW QUESTION # 38
While troubleshooting the SD-WAN data path, you run show vsf tunnel access-circuits ... detail and see the following encapsulation chain: VMLH, MPLS-over-GRE, IPsec-ESP, and VXLAN. What does this output primarily confirm?
- A. The traffic is being bridged without SD-WAN encapsulation.
- B. The traffic is bypassing the VOS data plane.
- C. The branch is using only plain-text GRE without encryption.
- D. The branch has created an SD-WAN tunnel encapsulation stack for overlay forwarding.
Answer: D
Explanation:
The correct answer is B . Versa's SD-WAN data-path troubleshooting documentation shows that show vsf tunnel access-circuits ... detail can display the access-circuit state and encapsulation chain used for tunnel forwarding. In the example, the output lists multiple encapsulations, including VMLH , MPLS-over-GRE , IPsec-ESP , and VXLAN . It also shows transport details such as source IP, destination IP, UDP transport, tunnel MTU, SPI values, and SLA state.
This confirms that the VOS data plane has built the SD-WAN tunnel encapsulation stack required to forward overlay traffic across the underlay. IPsec-ESP in the chain indicates encrypted tunnel handling, while VXLAN and other encapsulation components are part of the SD-WAN overlay forwarding structure.
The output does not indicate simple bridging, plain-text-only GRE, or bypass of the VOS data plane.
Instead, it proves that the packet path is being processed through the VOS tunnel forwarding framework and that the administrator is looking at the SD-WAN access-circuit tunnel state.
NEW QUESTION # 39
You are configuring the BGP routing protocol between a Versa Secure SD-WAN CPE with AS number
64514 and two upstream service providers: SP1 with AS number 64515 and SP2 with AS number 64519. You want to prefer BGP routes learned from AS 64515 over routes learned from AS 64519. Which BGP path attribute would be used to accomplish this task?
- A. The BGP MULTI_EXIT_DISC path attribute
- B. The BGP LOCAL_PREF path attribute
- C. The BGP NEXT_HOP path attribute
- D. The BGP ORIGIN path attribute
Answer: B
Explanation:
The correct answer is LOCAL_PREF . In BGP, the Local Preference attribute is used inside an autonomous system to influence which exit path is preferred for outbound traffic. In this scenario, the Versa Secure SD- WAN CPE receives routes from two upstream service providers, SP1 and SP2. To prefer routes learned from AS 64515 over routes learned from AS 64519, you would apply a BGP import or route policy that assigns a higher local preference to routes received from SP1. Versa SD-WAN design guidance shows this exact routing concept: an import policy can manipulate the Local-Pref attribute to prefer one advertised route path over another. The Versa output examples also display "Local Preference" as a BGP route attribute used in route selection.
MULTI_EXIT_DISC, or MED, is generally used to influence how a neighboring AS enters your AS, not how your CPE prefers routes learned from different upstreams. ORIGIN is part of BGP best-path selection but is not normally the administrative tool used to prefer one provider. NEXT_HOP identifies the next-hop address and does not directly define route preference.
NEW QUESTION # 40
A customer is running VOS Release 22.1.3 on both the speed-test client and server. Which sequence is used by the Versa speed test to calculate bandwidth?
- A. IKE test, ESP test, and VXLAN test
- B. Download test only
- C. Ping test, upload test, and download test
- D. Upload test only, then DNS lookup
Answer: C
Explanation:
The correct answer is C . Versa documentation states that for Releases 22.1.3 and later , the speed test factors in network latency to derive results. In these releases, the speed test is performed in three stages : a ping test, an upload test, and a download test. The ping test calculates link latency, and the speed test uses that latency data while performing the upload and download portions.
The same documentation notes that the speed test can measure bandwidth speeds up to 1 Gbps, with actual measurement depending on factors such as in-path shapers and latency. It also states that the test may use up to 45 MB of data per upload or download in the best case and 90 MB for a complete test.
Older releases behave differently. For Releases 21.2 and earlier, the speed test is performed in two stages: upload and download. Therefore, because the question specifically states Release 22.1.3 on both client and server, the correct sequence is ping, upload, and download.
NEW QUESTION # 41
You are troubleshooting a branch that cannot form SD-WAN overlay tunnels. The branch has WAN interfaces up, but you suspect remote endpoint objects were not learned. Which VSM command should you use to verify whether remote site objects were learned from BGP or from configuration?
- A. show interfaces brief
- B. show orgs org-services cgnat summary
- C. show vsm p2mp tunnel-remote-endpoint tenant < tenant-id >
- D. show system storage
Answer: C
Explanation:
The correct answer is A . Versa data-path troubleshooting documentation gives a specific VSM control-plane workflow for checking SD-WAN tunnel objects. After connecting to the VSM daemon, administrators can use show vsm p2mp local-tunnel-sites 0 to inspect local site objects. To check whether remote site objects were learned from BGP or from configuration , Versa instructs administrators to issue show vsm p2mp tunnel-remote-endpoint tenant < tenant-id > on the VSM control plane.
This command is highly relevant when local WAN interfaces are operational, but overlay tunnel formation is incomplete. It shows remote endpoints such as Controllers, hubs, or branches, along with site type, site name, branch ID, tenant ID, remote WAN link information, and tunnel state-related fields.
show interfaces brief confirms interface state and IP addresses, but it does not show learned remote SD- WAN endpoint objects. CGNAT summary is unrelated to tunnel endpoint learning. System storage is useful for disk checks, but not for SD-WAN overlay endpoint troubleshooting.
NEW QUESTION # 42
In an HA active-active deployment, one device has two WAN networks, INET-1 and MPLS-1 , and its peer also has two WAN networks, INET-2 and MPLS-2 . In this scenario, how many subinterfaces will be created on the cross-connect link between the devices by an HA active-active workflow?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
The correct answer is D . In a Versa HA active-active branch deployment, the cross-connect link between the two CPE devices is used to extend WAN transport reachability between the peers. Versa SD-WAN design documentation explains that, in an HA active-active design, a cross-connect cable between the two devices extends one device's transport VR to the other device and vice versa. For example, the documentation describes the cross-connect as extending the MPLS-Transport-VR to one device and the Internet- Transport-VR to the peer device.
In the question, there are four total WAN networks across the HA pair: INET-1 , MPLS-1 , INET-2 , and MPLS-2 . The HA active-active workflow must create separate logical subinterfaces on the cross-connect link for each WAN network so that each transport segment can be extended and kept logically separated across the two appliances. Therefore, the number of subinterfaces created on the cross-connect link equals the total number of WAN networks across the HA pair, which is four .
Options A, B, and C are incorrect because they undercount the number of required transport extensions. Two subinterfaces would only account for two WAN networks, but this design has four separate WAN transport networks.
NEW QUESTION # 43
A customer reports inconsistent application performance between two branches. You find that traffic is transmitted over the Internet circuit but returns over the MPLS circuit. Which CLI output field pair is most useful to confirm this asymmetry?
- A. Source zone and destination zone
- B. Local preference and MED
- C. Tenant ID and VSN ID
- D. RX WAN CKT and TX WAN CKT
Answer: D
Explanation:
The correct answer is B . Versa documentation describes checking for asymmetrical SD-WAN paths when troubleshooting bandwidth and throughput issues. It gives the example of traffic being transmitted on one transport network and returning on another transport network that has different bandwidth. To check whether traffic is traversing an asymmetrical SD-WAN path, Versa recommends using show orgs org organization- name sessions sdwan brief.
In that output, the key fields are RX WAN CKT and TX WAN CKT . If the SD-WAN paths are symmetrical, the circuits shown in the RX and TX WAN circuit fields must be the same on the local and remote sites. If traffic goes out over Internet and returns over MPLS, throughput may differ depending on the bandwidth and quality of each circuit.
Source and destination zones are security-policy concepts, while BGP local preference and MED are routing attributes. Tenant ID and VSN ID identify context, but they do not directly prove directional WAN-circuit asymmetry.
NEW QUESTION # 44
You configured a Versa speed-test server on a VOS device, but the client cannot start the bandwidth test. A firewall exists between the client and server. Which port must be allowed through the firewall?
- A. TCP 443
- B. UDP 53
- C. TCP 5201
- D. UDP 4790
Answer: C
Explanation:
The correct answer is A . Versa link-bandwidth troubleshooting documentation explains that a VOS device can be configured as a Versa speed-test client, a Versa speed-test server, or both simultaneously. After the server is configured, the client starts the test by initiating a TCP-based connection toward the speed-test server. The server listens on port 5201 . The documentation includes an explicit note that if the VOS device is behind a firewall, port 5201 must be open .
This is different from the SD-WAN overlay data path, which commonly uses UDP-based transport encapsulation, and different from internet speed-test traffic, which uses other ports depending on the specific test type. In this scenario, the question states that a Versa speed-test server was configured, so the relevant requirement is TCP 5201 reachability from the client to the server.
TCP 443 may be used for management or web access, UDP 4790 is associated with SD-WAN transport encapsulation, and UDP 53 is DNS. None of those replace TCP 5201 for Versa speed-test server operation.
NEW QUESTION # 45
You configured Direct Internet Access on your Versa branches using the workflow template. Which statement is true in this scenario?
- A. CGNAT is not required when you configure DIA services.
- B. You must define a CGNAT address pool and rule, and associate the rule with the LAN interface.
- C. DIA configured in a workflow automatically creates a CGNAT pool and rule, and associates it with the internet-facing network.
- D. You must define a CGNAT address pool and rule, and associate the rule with the internet-facing network.
Answer: C
Explanation:
The correct answer is C . In Versa Secure SD-WAN, Direct Internet Access, or DIA, provides local internet breakout from the branch rather than backhauling internet-bound traffic through a hub. Versa design documentation explains that the DIA architecture creates an internal connection between the tenant VRF and the WAN transport VR and uses CGNAT to translate internet-bound LAN traffic to the public IP address associated with the WAN transport interface. It specifically states that the main DIA components include the CGNAT function for translating internet-bound traffic and that DIA is configured using Director Workflows when configuring tunnels.
When the workflow template is used and the DIA option is selected for the internet breakout tunnel, Director automatically builds the required DIA infrastructure, including the NAPT/CGNAT configuration associated with the internet-facing transport network. This is why manual creation of the CGNAT pool and rule is not required in the workflow-based method. Option A describes a manual configuration approach, not the workflow-generated behavior. Option B is incorrect because NAT must be associated with the internet-facing breakout path, not simply the LAN interface. Option D is incorrect because DIA normally requires address translation for LAN users accessing the public internet.
NEW QUESTION # 46
Examine the exhibit below.
As an administrator of a Versa Secure SD-WAN deployment, you are asked to find the current bandwidth of each WAN circuit used for SD-WAN connectivity in a branch, but Versa Director is not displaying any information for the WAN circuits. In this scenario, what should be done to get the graph populated for all WAN circuits?
- A. Select Live Data for all WAN circuits in the dashboard.
- B. Unselect Live Data for the INET circuit and select it again.
- C. Select Live Data for MPLS circuits alone.
- D. Refresh the page to get the graphs populated in the dashboard.
Answer: A
Explanation:
The correct answer is B . In the exhibit, Versa Director shows multiple branch interfaces and a Live Data column. To populate the bandwidth graph with current real-time statistics for all WAN circuits, Live Data must be selected for each WAN circuit that should be monitored. Versa documentation states that from a Director node, administrators can monitor VOS devices, provider organizations, tenants, events, and alarms. It also explains that Versa Director, together with Versa Analytics, can poll VOS devices in real time to provide visibility into what is happening on those devices and to assist with troubleshooting.
Because the requirement is to find the current bandwidth of each WAN circuit, simply refreshing the page is not enough. Refreshing only reloads the dashboard; it does not enable real-time polling for interfaces that are not selected. Selecting Live Data only for MPLS circuits would populate only MPLS- related data and would not satisfy the requirement for all WAN circuits. Unselecting and reselecting only the INET circuit affects only that one circuit. Therefore, the correct operational step is to enable Live Data for all WAN circuits shown in the branch interface dashboard.
NEW QUESTION # 47
During branch onboarding, you need to verify whether the Controller has sent branch-connect and branch- disconnect notifications to Versa Director. Which CLI command should be used?
- A. show interfaces detail
- B. show alarms
- C. show system storage
- D. show cgnat acl info
Answer: B
Explanation:
The correct answer is A . Versa troubleshooting documentation states that after a branch device successfully establishes an IPsec connection to the Controller node, the Controller sends a notification to the Director node. To display the details of this notification, the documentation instructs administrators to issue the show alarms CLI command. It also provides examples using show alarms | match branchd | match br101 to view branch-connect and branch-disconnect events.
These alarm entries are valuable during onboarding because they show whether the branch reached the Controller, whether staging progressed, and whether the branch later disconnected. For example, branch lifecycle notifications include factory-default connection, staged connection, Stage 3 connection with WAN IP addresses, and branch disconnect events.
show system storage is useful for disk usage, show interfaces detail helps with link state, speed, duplex, and interface counters, and show cgnat acl info is used for CGNAT matching. None of those commands directly confirms branch lifecycle notifications between Controller and Director.
NEW QUESTION # 48
A branch using DIA with CGNAT reports that new internet sessions intermittently fail. CGNAT pool counters show increasing out-of-ports errors, while out-of-address errors remain zero. What is the most likely problem?
- A. The NAT pool has no available source ports left for allocation.
- B. The CGNAT rule is matching the wrong destination zone.
- C. The LAN routing instance is missing OSPF.
- D. The NAT pool has no IP addresses assigned.
Answer: A
Explanation:
The correct answer is A . Versa CGNAT troubleshooting documentation includes per-pool and resource counters that show allocation behavior and failures. The counters include values such as bindings allocated, bindings freed, allocation failures, out-of-address errors, and out-of-ports errors. It also shows that CGNAT source-port resources are divided and distributed to worker threads by Versa RFD/RFM, and that allocated source-port ranges can be viewed using show rfm table src-port allocated.
If out-of-ports errors increase while out-of-address errors remain zero, the pool still has usable translated IP addresses, but the available port resource for NAT bindings is exhausted. This commonly occurs when too many concurrent sessions share a limited public IP or source-port range. The corrective action would be to expand the NAT resource, add more public translated IPs, adjust port allocation, or reduce excessive session usage.
A missing NAT IP pool would more likely produce out-of-address problems. A wrong zone match might prevent translation entirely, and OSPF in the LAN VR is unrelated to CGNAT port-resource exhaustion.
