11.6.5 Interoperability between a Y.1731 MEP and 802.1ag MEPs
In general, an 802.1ag MEP cannot interoperate correctly with a Y.1731 MEP; that is, they cannot
correctly exchange CCM messages. Their respective standards do not provide compatibility
methods.
The Canoga Perkins 9145EMP 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 11-23 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.
