host name alone to ping the device because the mygroup.hpnetworking.net
domain has been configured as the domain name on the switch and the address
of a DNS server residing in that domain is also configured on the switch. The
commands for these steps are as follows:
Figure 4-3. Example of Configuring for a Local DNS Server and Pinging a Registered Device
However, for the same “mars-1” device, if mygroup.hpnetworking.net was not
the configured domain name, you would have to use the fully qualified domain
name for the device named mars-1:
Switch# ping6 mars-1.mygroup.hpnetworking.net
For further information and examples on using the DNS feature, refer to “DNS
Resolver” in appendix C, “Troubleshooting”, in the current
Management and
Configuration Guide
for your switch.
Viewing the Current Configuration
Use the
show ip dns
command to view the current DNS server configuration.
Use the
show run
command to view both the current DNS server addresses
and the current DNS domain name in the active configuration.
Operating Notes
In software release S.15.XX, DNS addressing is not configurable from a
DHCPv6 server.
Debug/Syslog for IPv6
The Debug/System logging (
Syslog
) for IPv6 feature provides the same logging
functions as the IPv4 version, allowing you to record IPv4 and IPv6 Event Log
and debug messages on a remote device to troubleshoot switch or network
HP Switch(config)# ip dns server-address priority 1 2001:db8::127:10
HP Switch(config)# ip dns domain-name mygroup.hpnetworking.net
HP Switch(config)# ping6 mars-1
