ccm
Variable

interval1s – One second (default)
interval10s – 10 seconds
interval1min – One minute
interval10min – 10 minutes
It takes a MEP 3.5 times the CCM interval to
determine a change in the status of its peer MEP. For
example, if the CCM interval is 1 second, a MEP will
detect failure of the peer 3.5 seconds after it
receives the first CCM failure message. If the CCM
interval is 10 minutes, the MEP will detect failure of
the peer 35 minutes after it receives the first CCM
failure message.
mhf
Variable
defMHFnone
defMHFdefault
defMHFexplicit
defMHFdefer
Determines whether MIPs are created on the MEG.
Options are:
defMHFnone – No MIPs are created.
defMHFdefault – MIPs are created on any service
point in the MEG.
defMHFexplicit – MIPs are created on the service
points of the MEG when a lower-level MEP exists on
the service point. This option is usually used when
the operator’s domain is encompassed by another
domain.
defMHFdefer – No MIPs are created.
Configuring MEPs (CLI)
Each MEP is attached to a service point in an Ethernet service. The service and service point must be configured
before you configure the MEP. See
Configuring Ethernet Services (CLI)
Each MEP inherits the same VLAN, C-VLAN, or S-VLAN configuration as the service point on which it resides. See
Configuring Service Points (CLI).
In order to set the VLAN used by CCM/LBM/LTM if the service point is defined ambiguously (for example PIPE,
Bundle-C, Bundle-S, or All-to-One), the service point’s C-VLAN/S-VLAN parameter should not be set to N.A.
To configure a MEP, you must:
1
Add MEPs to the relevant MA/MEG. In this stage, you add both local and remote MEPs. The only thing you
define at this point is the MEP ID. See
Adding Local and Remote MEPs (CLI)
2
Configure the local MEPs. At this point, you determine which MEPs are local MEPs. The system
automatically defines the other MEPs you configured in the previous step as remote MEPs. See
Configuring the Local MEPs (CLI)
3
Enable the Local MEPs. See
