database hold-time minutes
The default is 100 minutes.
The range is from 100 to 65535 minutes.
Continuity Check Messages
Continuity check messages (CCM) are periodic hellos.
Continuity check messages:
• discover MEPs and MIPs within a maintenance domain
• detect loss of connectivity between MEPs
• detect misconfiguration, such as VLAN ID mismatch between MEPs
• detect unauthorized MEPs in a maintenance domain
CCMs are multicast Ethernet frames sent at regular intervals from each MEP. They have a destination address
based on the MD level (01:80:C2:00:00:3X where X is the MD level of the transmitting MEP from 0 to 7). All
