HP ProCurve Series 3400cl Release Notes page 39

IP address of 10.10.100.27 is assigned a host name of accounts015 and another IP address of
10.10.100.33 is assigned a host name of sales021, then the switch configured with the domain
suffix evergreen.trees.org and a DNS server that resolves addresses in that domain can use the
host names to reach the devices with ping and traceroute commands:
ping accounts015
traceroute sales021
Basic Operation
■ When the switch is configured with only the IP address of a DNS server available to the
switch, then a ping or traceroute command, executed with a fully qualified domain name, can
reach a device found in any domain accessible through the configured DNS server.
■ When the switch is configured with both of the following:
• the IP address of a DNS server available to the switch
• the domain suffix of a domain available to the configured DNS server
then:
A ping or traceroute command that includes the host name of a device in the same domain
•
as the configured domain suffix can reach that device.
A ping or traceroute command that includes a fully qualified domain name can reach a
•
device in any domain that is available to the configured DNS server.
Example. Suppose the switch is configured with the domain suffix mygroup.procurve.net and the IP
address for an accessible DNS server. If an operator wants to use the switch to ping a host using the
DNS name "leader" assigned to an IP address used in that domain, then the operator can use either
of the following commands:
ProCurve# ping leader
10.28.229.220 is alive, time = 1 ms
ProCurve# ping leader.mygroup.procurve.net
10.28.229.220 is alive, time = 1 ms
Figure 3. Example of Using Either a Host Name or a Fully Qualified Domain Name
In the preceeding example, if the DNS server's IP address is configured on the switch, but a domain
suffix is not configured, then the fully qualified domain name must be used.
Note that if the target host is in a domain other than the domain configured on the switch, then:
