Argument Description
1-8191
Specifies the maintenance end point ID (mandatory) in the specified range.
UU/SS/PP
Target interface on which is used ad MEP.
in
Sets the MEP Direction to
in
the bridge.
out
Sets the MEP Direction to
out
the bridge.
Configuring a MEP for each of the DoSAPs of a service instance creates a MA to monitor the
connectivity.
The list of MEPs configured with identical values for MAID defines an MA.
Each Bridge has its own Maintenance Association managed object for an MA.
Each individual MEP is configured with a MEPID that is unique within that MA.
Each MEP is associated with a SAP that provides access to a single service instance.

Specifying MIP Creation Policy
The
mip-policy
command, in Maintenance Association mode, specifies the conditions in which
MIPs are automatically created on ports.
A MIP can be created on a port and VLAN, only when explicit or default policy has been defined
for them. For a specific port and VLAN a MIP will be created at the lowest of the levels.
Additionally, the level created should be the next higher than the MEP level defined for these port
and VLAN.
The
no
form of the command restores the default Policy.
By default, the decision regarding the MIPs is taken considering the setting of the enclosing
domain.
