Ethernet Connectivity Fault Management (ETH-CFM)
Page 108 7750 SR OS Services Guide
The following functions are supported:
• Enable and disable CC for an MEP
• Configure and delete the MEP entries in the CC MEP monitoring database manually. It is
only required to provision remote MEPs. Local MEPs shall be automatically put into the
database when they are created.
• CCM transmit interval in seconds: 0, 1, 10, 60, 600. Default: 10.
• CCM will declare a fault, when:
→ The CCM stops hearing from one of the remote MEPs for 3.5 times CC interval
→ Hears from a MEP with a lower MD level
→ Hears from a MEP that is not in our MA
→ Hears from a MEP that is in the same MA but not in the configured MEP list
→ Hears from a MEP in the same MA with the same MEP id as the receiving MEP
→ The CC interval of the remote MEP does not match the local configured CC interval
→ The remote MEP is declaring a fault
• An alarm is raised and a trap is sent if the defect is greater than or equal to the configured
low-priority-defect value.
