Configuring the Ethernet Local Management Interface
202
To configure E-LMI, perform the following steps:
• Configuring an OAM Protocol (CFM) on page 202
• Assigning the OAM Protocol to an EVC on page 202
• Enabling E-LMI on an Interface and Mapping CE VLAN IDs to an EVC on page 202
Configuring an OAM Protocol (CFM)
For information on configuring the OAM protocol (CFM), see “IEEE 802.1ag OAM
Connectivity Fault Management Overview” on page 181.
Assigning the OAM Protocol to an EVC
To configure an EVC, you must specify a name for the EVC using the evcsevc-id statement
at the [edit protocols oam ethernet] hierarchy level. You can set the EVC protocol for
monitoring EVC statistics to cfm or vpls using the evc-protocol statement and its options
at the [edit protocols oam ethernet evcs] hierarchy level.
You can set the number of remote UNIs in the EVC using the remote-uni-count number
statement at the [edit protocols oam ethernet evcs evcs-protocol] hierarchy level. The
remote-uni-count defaults to 1. Configuring a value greater than 1 makes the EVC
multipoint-to-multipoint. If you enter a value greater than the actual number of endpoints,
the EVC status will display as partially active even if all endpoints are up. If you enter a
remote-uni-count less than the actual number of endpoints, the status will display as
active, even if all endpoints are not up.
You can configure an EVC by including the evcs statement at the [edit protocols oam
ethernet] hierarchy level:
[edit protocols oam ethernet]
evcs evc-id {
evc-protocol (cfm (management-domain name management-association name ) | vpls
(routing-instance name)) {
remote-uni-count ; # Optional, defaults to 1
multipoint-to-multipoint;
# Optional, defaults to point-to-point if remote-uni-count is 1
}
}
Enabling E-LMI on an Interface and Mapping CE VLAN IDs to an EVC
To configure E-LMI, include the lmi statement at the [edit protocols oam ethernet]
hierarchy level:
[edit protocols oam ethernet]
lmi {
polling-verification-timer value;
# Polling verification timer (T392), defaults to 15 seconds
status-counter count; # Status counter (N393), defaults to 4
interface name {
evc evc-id {
default-evc;
