Chapter 21: TDM Services and Interfaces (CLI)
Adding a Maintenance Association (MA) (CLI)
Maintenance Associations (MAs) define Maintenance End Points (MEPs), and perform continuity checks by sending
Continuity Check Messages (CCMs) between the MEPs. This is the mechanism by which PTP 820G or PTP 820F
monitors the status of both paths in a protected TDM service and determines when a switchover is necessary.
For PTP 820F and PTP 820G, you can configure up to 64 MAs.
Each of the two TDM tunnels that make up a path-protected TDM service must be assigned its own MA. Each MA
must have a unique local MEP ID and a unique remote MEP ID. Each MA must also include a defined VLAN, which
corresponds to the VLAN that will be assigned to the TDM tunnel associated with the MA.
To add an MA, enter the following command in pwe3 view:
pwe3> pwe3 soam ma add slot <slot> id <id> name <name> md-id <md-id>
local-mep <local-mep> remote-mep <remote-mep> vlan-type <vlan-type> vid
<vid>
