The Canoga Perkins 9145E NID does, however, provide a configuration method that will allow
interoperability between a Y.1731 MEP and an 802.1ag MEP operating in the same
administrative domain at the same level.
Figure 11-18 Create a New Maintenance Entity Group screen
To configure the operation of the MEPs in compatible mode, use the following steps:
1. For the 802.1ag MEP, configure the corresponding MD Domain Name as empty. Only the
MA name will be transmitted in the CCM packet.
2. For the Y.1731 MEP, configure the corresponding MEG name in Character string mode.
The MEG name configured for the Y.1731 MEP must match the name defined for the MA
of the 802.1ag MEP.
NOTE: Some limitations apply to interoperability between Y.1731 and 802.1ag MEPs. An LTR
from a Y.1731 MEP working in inter-op mode is not recognized by an 802.1ag MEP because they
use different rules to construct and validate the message. An LTR can be initiated from the
Y.1731 MEP only. An LBM can be sent from either MEP.
