Troubleshooting Guide

Important:
CFM supports one MEP or MIP for each SPBM B-VLAN only. This means that if you want to
use these autogenerated MEPs, you cannot use your existing CFM configuration. You must first
remove the existing MEP or MIP on the SPBM B-VLAN. If you want to continue configuring
MEPs manually, skip this procedure.
Procedure
1. Enter Global Configuration mode:
enable
configure terminal
2. Configure the maintenance level for every CFM SPBM MEP and MP level on all the SPBM
B-VLANs:
cfm spbm level <0-7>
You can change this level from the default of 4 either before or after the feature is enabled.
Only configure global CFM at one MD level for each chassis for each VLAN type.
3. Assign a global CFM MEP ID for all CFM SPBM MEPs:
cfm spbm mepid <1-8191>
4. Enable the autogenerated CFM for SPBM B-VLANs globally:
cfm spbm enable
5. (Optional) Configure the maintenance level for every CFM SPBM MEP and MP level on all
the SPBM B-VLANs to the default:
default cfm spbm level
6. (Optional) Assign a global CFM MEP ID for all CFM SPBM MEPs to the default:
default cfm spbm mepid
7. (Optional) Disable the global CFM MEPs and MIPs:
no cfm spbm enable
8. Display the global CFM MEP configuration:
show cfm spbm
Example
Configure autogenerated CFM MEPs and MIPs:
VSP-4850GTS>enable
VSP-4850GTS#configure terminal
VSP-4850GTS(config)#cfm spbm level 6
VSP-4850GTS(config)#cfm spbm mepid 4
VSP-4850GTS(config)#cfm spbm enable
VSP-4850GTS(config)#show cfm spbm
