System Management Software Configuration Guide for Cisco IE 2000U and Connected Grid Switches
Chapter 17 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.
EXAMPLE
Switch(config)# ethernet lmi global
Switch(config)# interface gigabitethernet0/2
Switch(config-if)# ethernet lmi t391 30
Switch(config-if)# end
Step 4
interface interface-id Define an interface to configure as an E-LMI
interface, and enter interface configuration mode.
Step 5
ethernet lmi interface 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.
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
copy running-config startup-config (Optional) Save your entries in the configuration
file.
