Troubleshooting an Extended Edge Switching Topology
The following information provides tips on how to verify and troubleshoot your Extended Edge Switching topology.
Commands for Verifying/Troubleshooting Extended Edge Switching Topology
Use the following commands to verify and troubleshoot the Extended Edge
Switching topology:
- show configuration {module-name} {detail} with vpex as the module-name—shows cascade port configuration.
- show configuration {module-name} {detail} with vlan as the module-name or with | grep sharing—shows LAG configuration.
- show configuration {module-name} {detail} with devmgr as the module-name—shows slot module type configuration.
- show vpex—shows mapping between cascade port and slot number.
- show slot {slot {detail} | detail }—shows status of BPE slot.
- show vpex ports {ports_list}—shows the status of the CSP control plane connections for each cascade port.
- show vpex topology { port port_num} {summary | detail}—shows the detected topology type, status, ring status (if applicable), and bridge port extender (BPE) interconnections.
Commands for Verifying/Troubleshooting Redundant Controlling Bridges (CBs)/MLAGs
To verify and troubleshooting the MLAG setup, use the following commands:
show mlag peer {peer_name}—shows if MLAG peer is up.
show configuration {module-name} {detail} with vsm as the module-name—shows MLAG port configuration.
Limitations When Using Automation to Set up Redundant CBs/MLAGs
The following limitations apply when using automation to set up redundant CBs.
| Limitation | Workaround |
|---|---|
| If the CB has MLAG peer configuration, but its MLAG peer is down, you cannot enable auto-configuration. |
|
| If a BPE is configured before MLAG peer is configured, auto-configuration does not configure the MLAG port for the previously configured BPE. | Manually configure MLAG port for the previously configured BPE by setting the MLAG port ID to 5000 plus the BPE‘s slot number. |
