Chapter 39 Configuring Ethernet OAM, CFM, and E-LMI
Configuring E-LMI
Use the no ethernet lmi global configuration command to globally disable E-LMI. Use the no form of
the ethernet lmi interface configuration command with keywords to disable E-LMI on the interface or
to return the timers to the default settings.
Use the show ethernet lmi commands to display information that was sent to the CE from the status
request poll. Use the show ethernet service commands to show current status on the device.
Ethernet OAM Manager Configuration Example
This is a simple example of configuring CFM and E-LMI with OAM manager on a PE device and on a
CE device. You can configure the switch as either the PE device or the CE device.
Provider-Edge Device Configuration
This example shows a sample configuration of OAM manager, CFM, and E-LMI on the PE device:
Switch# config t
Switch(config)# ethernet cfm domain Top level 7
Switch(config)# ethernet cfm domain Provider level 4
Switch(config-ether-cfm)# service customer_1 vlan 101
Switch(config-ether-cfm)# mep crosscheck mpid 404 vlan 101
Switch(config-ether-cfm)# exit
Switch(config)# ethernet cfm domain Operator_level 2
Switch(config-ether-cfm)# service operator_1 vlan 101
Step 6
ethernet lmi {n391 value | n393 value | t391 value|
t392 value}
Configure E-LMI parameters for the UNI.
The keywords have these meanings:
• n391 value—Set the event counter on the customer
equipment. The counter polls the status of the UNI and
all Ethernet virtual connections (EVCs). The range is
from 1 to 65000; the default is 360.
• n393 value—Set the event counter for the metro
Ethernet network. The range is from 1 to 10; the
default is 4.
• t391 value—Set the polling timer on the customer
equipment. A polling timer sends status enquiries and
when status messages are not received, records errors.
The range is from 5 to 30 seconds; the default is 10
seconds.
• t392 value—Set the polling verification timer for the
metro Ethernet network or the timer to verify received
status inquiries. The range is from 5 to 30 seconds, or
enter 0 to disable the timer. The default is 15 seconds.
Note The t392 keyword is not supported when the switch
is in CE mode.
Step 7
end Return to privileged EXEC mode.
Step 8
show ethernet lmi evc Verify the configuration.
Step 9
