Chapter 8: IP Routing Configuration Guide

Monitoring RARP

You can use the following commands to obtain information about the SSR’s RARP configuration:

Display the interfaces to which the	rarpd show interface
RARP server responds.

Display the existing MAC-to-IP	rarpd show mappings
address mappings

Display RARP statistics.	statistics show rarp <InterfaceName>all

Configuring DNS Parameters

The SSR can be configured to specify DNS servers, which supply name services for DNS requests. You can specify up to three DNS servers.

To configure three DNS servers and configure the SSR’s DNS domain name to “mrb.com”:

ssr(config)# system set dns server “10.1.2.3 10.2.10.12 10.3.4.5” domain mrb.com

Configuring IP Services (ICMP)

The SSR provides ICMP message capabilities including ping and traceroute. The ping command allows you to determine the reachability of a certain IP host, while the traceroute command allows you to trace the IP gateways to an IP host.

Configuring IP Helper

The ip helper-addresscommand allows the user to forward specific UDP broadcast from one interface to another. Typically, broadcast packets from one interface are not forwarded (routed) to another interface. However, some applications use UDP broadcast to detect the availability of a service. Other services, for example BOOTP/DHCP require broadcast packets to be routed so that they can provide services to clients on another subnet. An IP helper can be configured on each interface to have UDP broadcast packets forwarded to a specific host for a specific service or forwarded to all other interfaces.

You can configure the SSR to forward UDP broadcast packets received on a given interface to all other interfaces or to a specified IP address. You can specify a UDP port number for which UDP broadcast packets with that destination port number will be forwarded. By default, if no UDP port number is specified, the SSR will forward UDP broadcast packets for the following six services:
