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
