Chapter 10 Configuring Ethernet OAM
Step 10
continuity-check interval value (Optional) Set the interval at which continuity check
messages are sent. The available values are 100 ms,
1 second, 10 seconds, 1 minute and 10 minutes. The default
is 10 seconds.
Note Because faster CCM rates are more CPU-intensive,
we do not recommend configuring a large number
of MEPs running at 100 ms intervals.
Step 11
continuity-check loss-threshold threshold-value (Optional) Set the number of continuity check messages to
be missed before declaring that an MEP is down. The range
is 2 to 255; the default is 3.
Step 12
maximum meps value (Optional) Configure the maximum number of MEPs
allowed across the network. The range is from 1 to 65535.
The default is 100.
Step 13
sender-id {chassis | none} (Optional) Include the sender ID TLVs, attributes
containing type, length, and values for neighbor devices.
• chassis—Send the chassis ID (host name).
• none—Do not include information in the sender ID.
Step 14
mip auto-create [lower-mep-only | none] (Optional) Configure auto creation of MIPs for the service.
• lower-mep-only—Create a MIP only if there is a MEP
for the service in another domain at the next lower
active level.
• none —No MIP auto-create.
Step 15
exit Return to ethernet-cfm configuration mode.
Step 16
mip auto-create [lower-mep-only] (Optional) Configure auto creation of MIPs for the domain.
• lower-mep-only—Create a MIP only if there is a MEP
for the service in another domain at the next lower
active level.
Step 17
mep archive-hold-time minutes (Optional) Set the number of minutes that data from a
missing maintenance end point is kept before it is purged.
The range is 1 to 65535; the default is 100 minutes.
Step 18
exit Return to global configuration mode.
Step 19
interface interface-id Specify an interface to configure, and enter interface
configuration mode.
Step 20
service instance number ethernet name Specify the service instance number and the name of the
EVC.
Step 21
cfm mip level level-id (Optional) Configure a customer level or service-provider
level maintenance intermediate point (MIP) for the
interface. The MIP level range is 0 to 7.
Note This step is not required if you have entered the
ethernet cfm mip auto-create global
configuration command or the mip auto-create
ethernet-cfm or ethernet-cfm-srv configuration
mode.
