Chapter 8: IP Routing Configuration Guide

Specifying IP Interfaces for RARP

The rarpd set interface command allows you to specify which interfaces the SSR’s RARP server responds to when sent RARP requests. You can specify individual interfaces or all interfaces. To cause the SSR’s RARP server to respond to RARP requests from interface int1:

ssr(config)# rarpd set interface int1

Defining MAC-to-IP Address Mappings

The rarpd add command allows you to map a MAC address to an IP address for use with RARP. When a host makes a RARP request on the SSR, and its MAC address has been mapped to an IP address with the rarp add command, the RARP server on the SSR responds with the IP address that corresponds to the host’s MAC address. To map MAC address 00:C0:4F:65:18:E0 to IP address 10.10.10.10:

ssr(config)# rarpd add hardware-address 00:C0:4F:65:18:E0 ip-address 10.10.10.10

There is no limit to the number of address mappings you can configure.

Optionally, you can create a list of mappings with a text editor and then use TFTP to upload the text file to the SSR. The format of the text file must be as follows:

MAC-address1 IP-address1 MAC-address2 IP-address2

...

MAC-addressnIP-addressn

Then place the text file on a TFTP server that the SSR can access and enter the following command in Enable mode:

ssr# copy tftp-server to ethers TFTP server? <IPaddr-of-TFTP-server>Source filename? <filename>
