Configuring RLMI
This chapter describes how to configure a Resilient Link Management Interface
(RLMI), which provides resiliency by monitoring LMI status, and explains how to
configure RLMI on Frame Relay UNI/NNI logical ports, and on ATM Network
Interworking for Frame Relay NNI logical ports on 1-port ATM IWU OC-3c/STM-1
and 1-port ATM CS DS3/E3 cards.
An RLMI preferred/backup pair can be a combination of any two Frame Relay
UNI/NNI physical links. For example, a preferred Universal Input/Output (UIO) V.35
and a backup T1. In addition, the ATM Network Interworking for Frame Relay NNI
logical port is supported on the B-STDX 1-port ATM CS DS3/E3 and 1-port ATM
IWU OC-3c/STM-1 cards. Each RLMI preferred/backup pair is configured
independently from other pairs.
