Chapter 4: Configuration Overview

Frame Relay/Maintenance Protocol

Write security: 3, Read security: 5

The Frame Relay maintenance protocol is used on the WAN port. The maintenance protocol is used to send link status and virtual cir- cuit information between Frame Relay switches and other devices (such as routers) that communicate with them. Possible choices are listed below.

Annex D(def)

An ANSI standard that is most commonly used

 

in the US.

 

 

Annex A

The CCITT European standard.

 

 

LMI

Used by some carriers in the U.S.

 

Developed by a vendor consortium and known

 

as the “consortium” management interface spec-

 

ification.

 

 

Static

Select when there is no Frame Relay switch in

 

the circuit. The DLCIs are assigned in the DLCI

 

Mapping and must be the same for the device it

 

will communicate with.

 

 

Frame Relay/Polling Frequency Write security: 3, Read security: 5

This parameter is the interval that the Router Option Module polls the Frame Relay switch using the maintenance protocol selected above. The Router Option Module is required to poll the Frame Re- lay switch periodically to determine whether the link is active. The value is in seconds and ranges from 5 to 30 seconds.

Frame Relay/DLCI Mapping

This menu allows each DLCI to be mapped to a particular protocol. Each protocol parameter can be individually configured for each DLCI. By factory default, the DLCI map is empty.

When empty and a maintenance protocol other than static is used, the Router Option Module will poll the switch to determine which DLCIs are active. These active DLCIs will attempt to determine the IP and IPX addresses on the other end of the virtual circuit using In- verse ARP (IARP). If there is a response, the network learned will be added to the router tables and the virtual circuit will be treated as an unnumbered interface. Bridge mode is not attempted in this case.
