Chapter 15 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.
Customer-Edge Device Configuration
This example shows the commands necessary to configure E-LMI on the CE device.
This example enables E-LMI globally, but you can also enable it only on a specific interface. However,
if you do not enter the ethernet lmi ce global configuration command, the interface will be in PE mode
by default.
Router# config t
Router(config)# ethernet lmi global
Router(config)# ethernet lmi ce
Router(config)# exit
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 router
is in CE mode.
