Syntax
ethernet cfm cc level 0-7 vlan vlan-id interval msecs
• vlan-id —VLAN ID representing a service instance that is monitored by
this maintenance association. The range is 1-4093.
•
msecs —Time interval between successive transmissions for all MEPs in
the Maintenance Association. The possible values are 3.3, 10, 100, 1000,
10000, 60000, and 600000 milliseconds.
Default Configuration
CCMs are not sent by default. The default CCM interval is 3.3milliseconds,
except on the N3200 Series switches, where it is 1000 milliseconds.
Command Mode
Global Configuration mode
User Guidelines
The N3200 Series switches do not support hardware-based Connectivity Fault
Management. The lowest configurable value for the Continuity Check Message
interval is one thousand milliseconds. Therefore, ERP failover on the N3200
platform is on the order of multiple seconds.
