Starting in software release 7.1.1 for the ERS 8800, release 3.4 for the VSP 9000, release 3.0 for
the VSP 4000, 5.7 for the ERS 4800, and 10.2 for the VSP 7000, CFM commands will now
automatically create a MEP and a MIP at a specific level for every SPB B-VLAN provisioned on the
switch. Hence, you no longer have to configure explicit MEPs and MIPs and associated VLANs
with MEPs and MIPs. Previously configured MIPs and MEPs will still continue to work if you
upgrade from either 7.0 or 7.1 to release 7.1.1.x. In summary:
Auto-generated CFM commands create a MEP and a MIP at a specified level for every
SPBM B-VLAN on the chassis
No more having to configure explicit MEPs and MIPs and associate multiple VLANs with
MEPs and MIPs
Previously configured MEPs and MIPS will continue to work
Auto-generated MEPs and MIPs respond to l2ping, l2traceroute, and l2tracetree in the
same manner as in 7.1
CFM extended to support C-VLANs in addition to existing support for B-VLANs.
This enables you to isolate a connectivity fault in either the SPBM cloud or in a
customer domain.
