Faults can be detected using Continuity Check messages at any of the four MA categories. Once a
fault is detected, Link Trace can be used to narrow down the location of the fault. Depending on the
location of the fault, a different MA category may need to be used to further isolate the location of
the fault.
802.1ag for Link MA
A new MA type is supported for Link MA.
Brocade(config- dot1ag -DONAME) #ma-name MANAME link-MA priority 4
Brocade(config- dot1ag -DONAME-MANAME) # mep 2 down port eth 1/1
Syntax: ma-name MANAME {vlan-id vlan-id | vpls-id vpls-id | [vll [vll-name]|[vll-id]|vll-local
[vll-name] | link-MA } priority priority
Only the down MEP configuration is allowed for a link-MA.
Syntax: mep mep-id [ up | down ] [ vlan vlan-id port port-id | port port-id ]
