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:
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:
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:
Then place the text file on a TFTP server that the SSR can access and enter the following
command in Enable mode:
ssr(config)# rarpd set interface int1
ssr(config)# rarpd add hardware-address 00:C0:4F:65:18:E0 ip-address 10.10.10.10
MAC-address1 IP-address1
MAC-address2 IP-address2
...
MAC-addressn IP-addressn
