Troubleshooting

DNS Resolver

Configuring switch “A” with the domain name and the IP address of a DNS
server for the domain enables the switch to use host names assigned to IP
addresses in the domain to perform

ping and traceroute actions on the devices

in the domain. To summarize:

Entity:

Identity:

DNS Server IP Address

10.28.229.10

Domain Name (and Domain Suffix for Hosts in

pubs.outdoors.com

the Domain)

Host Name Assigned to

10.28.229.219 by the

docservr

DNS Server

Fully Qualified Domain Name for the IP address

docservr.pubs.outdoors.com

Used By the Document Server (

10.28.229.219)

Switch IP Address

10.28.192.1

Document Server IP Address

10.28.229.219

With the above already configured, the following commands enable a DNS-
compatible command with the host name

docserver to reach the document

server at 10.28.229.219.

ProCurve(config)# ip dns server-address 10.28.229.10

ProCurve(config)# ip dns domain-name pubs.outdoors.com
