Cisco Systems OL-7396-01 Manual De Usuario

A keepalive interval must be set to configure the LMI. By default, this interval is 10 seconds and, per 
the LMI protocol, must be set as a positive integer that is less than the lmi-t392dce interval set on the 
interface of the neighboring switch. 

To set the keepalive interval, perform the following steps, beginning in global configuration mode:

The following example configures the LMI keepalive interval to 30 seconds:

Switch(config)# interface serial 1/1/0:1

Switch(config-if)# keepalive 30

To display the LMI keepalive interval, perform the following task in user EXEC mode:

The following example displays the LMI keepalive interval of a Frame Relay port adapter:

Switch> show interfaces serial 1/1/0:1

Serial1/1/0:1 is up, line protocol is up

  Hardware is FRPAM-SERIAL

  MTU 4096 bytes, BW 640 Kbit, DLY 0 usec, rely 255/255, load 1/255

Encapsulation FRAME-RELAY IETF, loopback not set, keepalive set (30 sec)

  LMI enq sent  5163, LMI stat recvd 5144, LMI upd recvd 0, DTE LMI up

  LMI enq recvd 5154, LMI stat sent  5154, LMI upd sent  0, DCE LMI up

  LMI DLCI 1023  LMI type is CISCO  frame relay NNI

  Last input 00:00:04, output 00:00:20, output hang never

You can set various optional counters, intervals, and thresholds to fine-tune the operation of your LMI 
on your Frame Relay devices. Set these attributes by performing one or more of the following steps, 
beginning in global configuration mode:

Switch(config)# interface serial 
card/subcard/port:cgn

Switch(config-if)# 

Selects the interface to be configured.

Switch(config-if)# keepalive number

Selects the keepalive interval.
