DNS Resolver

As mentioned under “Basic Operation” on page C-71, if the DNS entry config-

ured in the switch does not include the domain suffix for the desired target,

then you must use the target host’s fully qualified domain name with DNS-

compatible commands. For example, using the document server in Figure C-

29 as a target:

ProCurve# ping docservr.pubs.outdoors.com

10.28.229.219 is alive, time = 1 ms

ProCurve# traceroute docservr.pubs.outdoors.com

traceroute to 10.28.229.219

1 hop min, 30 hops max, 5 sec. timeout, 3 probes

1 10.28.192.2 1 ms 0 ms 0 ms

2 10.28.229.219 0 ms 0 ms 0 ms

Viewing the Current DNS Configuration

The show ip command displays the current domain suffix and the IP address

of the highest priority DNS server configured on the switch, along with other

IP configuration information. If the switch configuration currently includes a

non-default (non-null) DNS entry, it will also appear in the show run command

output.
