Configuring E-LMI

Enabling E-LMI

You can enable E-LMI globally or on an interface and configure the switch as a CE device. Beginning
in privileged EXEC mode, follow these steps to enable for E-LMI on the switch or on an interface. Note
that the order of the global and interface commands determines the configuration. The command that is
entered last has precedence.

to return the timers to the default settings.

Purpose
Enter global configuration mode.
Globally enable E-LMI on all interfaces.
Configure the switch as an E-LMI CE device.
Define an interface to configure as an E-LMI interface, and
enter interface configuration mode.
Configure Ethernet LMI on the interface. If E-LMI is
enabled globally, it is enabled on all interfaces unless you
disable it on specific interfaces. If E-LMI is disabled
globally, you can use this command to enable it on
specified interfaces.
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 UNIs.
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.
The t392 keyword is not supported when the switch
Note
is in CE mode.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.
