config>port>serial>v35>channel-group>frame-relay

config>port>serial>x21>channel-group>frame-relay

Description

This command configures the LMI type for frame relay interfaces. LMIs are sets of enhancements to the basic frame relay specification.

Default

itu

Parameters

ansi

specifies ANSI T1.617 Annex D

itu

specifies ITU-T Q933 Annex A

none

disable frame relay LMI on the port/channel

rev1

mode

Syntax

mode {dce | dte | bidir}

no lmi-type

Context

config>port>tdm>ds1>channel-group>frame-relay

config>port>tdm>ds3>frame-relay

config>port>tdm>e1>channel-group>frame-relay

config>port>tdm>e3>frame-relay

config>port>serial>v35>channel-group>frame-relay

config>port>serial>x21>channel-group>frame-relay

Description

This command sets the frame relay interface to the DCE, DTE, or bidirectional mode of LMI operation. The DTE mode causes the router to send status enquiries over the interface. The DCE mode causes the router to respond to status enquiries. In bidirectional mode, the router performs both DTE and DCE operation over the FR interface. The bidirectional mode applies to the ANSI and ITU LMI types only.

This feature is used when two routers are connected back-to-back, running frame relay encapsulation.

Default

dce

Parameters

dce

specifies the DCE mode

dte

specifies the DTE mode

bidir

the bidirectional mode for LMI types ANSI and ITU

The no form of this command returns the n391dte counter to the default value.

Default

6

intervals

sets the number of exchanges to be done before requesting a full-status report. A value of 1 specifies to receive full-status messages only.

config>port>serial>x21>channel-group>frame-relay

Description

This command configures the DCE error threshold for the frame relay LMI. The threshold specifies the number of errors needed to bring down a link.

The no form of this command returns the n392dce counter to the default value.

Default

3

Parameters

threshold

sets the number of errors that will put the channel in an operationally down state

Values

1 to 10
