SNR S2940-8G-v2 Switch Configuration Guide
CFM-OAM Configuration
– MA name: 1
∼
43 characters straing.It can be formed by letter, number, underline and
the first and the last character cannot be underline. The sum of MA and the domain
name cannot excess than 44 characters.
• In the same level, a primary vlan can only be related by one MA.
• MD level, MA related pvlan and UP/DOWN attribute cannot be changed after develop
• Need to build up the MEP ID before configure the MEP and RMEP
• MEP ID in one MA , after configured as MEP, the nit cannot be change to configure RMEP
• he DOWN attribute of MA in one facility can only allow existing one MEP; one UP attribute
MA can allow to exist of several of MEP, but it cannot allow to configure several identical MA
MEP to the same port.
2. Cannot build up the CC connection
• Through the show ethernet cfm to checking, ensure both port's level, MD name, MA name,
MA related pvlan are the same.
• Ensure the configuration of RMEP of this port is same with the configured MEP ID at the
other port.
• Ensure this port and the other port opened the CC sending and checking function
• Ensure the CCM sending period is the same for two port
• Configured the down mep on the port, then mep will receive the message from this port. If
it configured the up mep, then the mep will receive the messages from others ports. Please
ensure that the up mep configuration is on the non-receiving port.
• The port that is blocking by STP protocol cannot receiving, sending, replying the CFM mes-
sages. If it is configured as MEP, then even if that port was blocked by the STP protocol,
it can still sending and receiving CCM messages. Only the second layer Ethernet port can
support the CFM function.
• MEP and MIP can configure on the port channel, but at the same time, port channel config-
ured MEP and MIP will ineffective on the members. If you want to increase the CFM MEP
and MIP port to port channel, then that port's MEP and MIP will ineffective as well. If you
want to recover the MEP and MIP on the port, then need to delete the port-channel from this
port.
3. Cannot create the MIP point
• Ensure the develop rules of MIP is correct
– Default rules: If there is not a higher level of MEP on the port, and at the same time,
lower level of MIP does not exist, then it will build up MIP on particular port at this level.
– Explicit rules: If there is not a higher level of MEP on the port, but at the same time,
lower level of maintenance mid-point does not exist, then it will build up the mid-point
depends on whether there is a maintenance base point on lower level.
