At a public library in Portland, the observation may be useful for a separate VSF member roles and stack consistency test, but it does not establish that an interface is reachable after failover but hosts still ARP for a decommissioned gateway address has been resolved. The relevant check is the First-hop gateway redundancy and failover outcome.

At a public library in Portland, this measures a different network requirement, Multi-chassis LAGs and active paths. The case describes that an interface is reachable after failover but hosts still ARP for a decommissioned gateway address, so accepting this result would leave the primary fault without direct verification.

At a public library in Portland, this would verify VSX inter-switch link and keepalive, not the failure reported in this scenario. The requested closure criterion instead concerns First-hop gateway redundancy and failover: hosts retain the intended gateway identity and route through an available peer when the active first-hop device is lost.

At a regional hospital campus in Richmond, the option addresses Layer-two edge protection and BPDU controls rather than the reported issue. For the stated symptom, the expected evidence is that tagged and untagged test frames enter their intended VLANs on both ends and unauthorized VLANs are not carried.

At a regional hospital campus in Richmond, that change is aimed at RSTP root election and loop prevention, not at the actual fault: a wireless AP management VLAN is untagged on the switch but the upstream trunk expects it tagged. A successful repair here must show that tagged and untagged test frames enter their intended VLANs on both ends and unauthorized VLANs are not carried.

Although this is a valid design approach for SVI gateway and inter-VLAN reachability in an appropriate case, it leaves the VLAN trunk and native VLAN consistency dependency untested. The observed condition at a regional hospital campus in Richmond is that a wireless AP management VLAN is untagged on the switch but the upstream trunk expects it tagged.

At a regional hospital campus in Richmond, this measures a different network requirement, DHCP snooping and rogue DHCP protection. The case describes that a wireless AP management VLAN is untagged on the switch but the upstream trunk expects it tagged, so accepting this result would leave the primary fault without direct verification.

At a regional hospital campus in Richmond, this would verify LACP aggregation and member consistency, not the failure reported in this scenario. The requested closure criterion instead concerns VLAN trunk and native VLAN consistency: tagged and untagged test frames enter their intended VLANs on both ends and unauthorized VLANs are not carried.

Although this is a valid design approach for DHCP snooping and rogue DHCP protection in an appropriate case, it leaves the VLAN trunk and native VLAN consistency dependency untested. The observed condition at a hotel campus in Vancouver is that a wireless AP management VLAN is untagged on the switch but the upstream trunk expects it tagged.

At a hotel campus in Vancouver, the option addresses SVI gateway and inter-VLAN reachability rather than the reported issue. For the stated symptom, the expected evidence is that tagged and untagged test frames enter their intended VLANs on both ends and unauthorized VLANs are not carried.

Although this is a valid design approach for Ingress ACL enforcement and least privilege in an appropriate case, it leaves the VLAN trunk and native VLAN consistency dependency untested. The observed condition at a hotel campus in Vancouver is that a wireless AP management VLAN is untagged on the switch but the upstream trunk expects it tagged.

At a manufacturing complex in Detroit, the option addresses Ingress ACL enforcement and least privilege rather than the reported issue. For the stated symptom, the expected evidence is that tagged and untagged test frames enter their intended VLANs on both ends and unauthorized VLANs are not carried.

At a manufacturing complex in Detroit, that change is aimed at RSTP root election and loop prevention, not at the actual fault: a new voice VLAN is configured on both switches but omitted from the inter-switch allowed VLAN list. A successful repair here must show that tagged and untagged test frames enter their intended VLANs on both ends and unauthorized VLANs are not carried.

At a public safety training center in Oslo, the option addresses Layer-two edge protection and BPDU controls rather than the reported issue.

At a design studio in Berlin, that change is aimed at RSTP root election and loop prevention, not at the actual fault: a downstream switch places untagged frames into a different native VLAN than the aggregation switch. A successful repair here must show that tagged and untagged test frames enter their intended VLANs on both ends and unauthorized VLANs are not carried.
