Configure 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 DNS servers, enter the following command in Configure mode:
Configure a DNS server.
You can also specify a domain name for the SSR. The domain name is used by the SSR to
respond to DNS requests.
To configure a domain name, enter the following command in Configure mode:
Configure a domain name.

Configure IP Services (ICMP)

The SSR provides ICMP message capabilities including ping and traceroute. Ping allows
you to determine the reachability of a certain IP host. Traceroute allows you to trace the IP
gateways to an IP host.
To access ping or traceroute on the SSR, enter the following commands in Enable mode:
Specify ping.
Specify traceroute.

Configure IP Helper

You can configure the SSR to forward UDP broadcast packets recieved on a given interface
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:
• BOOTP/DHCP (port 67 and 68)
• DNS (port 37)
• NetBIOS Name Server (port 137)
