Explanation
To troubleshoot the bridge configuration and restore access to the application, you need to follow these steps:
Log in to the NSX Manager UI with admin credentials. The default URL is
https://<nsx-manager-ip-address>.
Navigate to Networking > Segments and select the overlay segment that is bridged to the VLAN-backed port group. For example, select Web-01 segment that you created in Task 2.
Click Bridge > Set and verify the configuration details of the bridge. Check for any discrepancies or errors in the parameters such as bridge name, bridge ID, VLAN ID, edge node, etc.
If you find any configuration errors, click Edit and modify the parameters accordingly. Click Save to apply the changes.
If you do not find any configuration errors, check the connectivity and firewall rules between the overlay segment and the VLAN-backed port group. You can use ping or traceroute commands from the NSX Edge CLI or the vSphere Web Client to test the connectivity. You can also use show service bridge command to check the status of the bridge service on the NSX Edge.
If you find any connectivity or firewall issues, resolve them by adjusting the network settings or firewall rules on the NSX Edge or the vSphere Distributed Switch.
After resolving the issues, verify that the bridge is functioning and the Bridge-VM is responding to ICMP requests from the main console.You can also check the MAC addresses learned by the bridge on both sides of the network using show service bridge mac command on the NSX Edge CLI.
