C-80 Troubleshooting DNS Resolver Basic Operation ■ When the switch is configured wit h only the IP address of a DNS server available to the switch, then a DNS-compatible command, executed with a fully qualified doma in name, can reac h a device found in any domain accessible through the configured DNS se rver . ■ When the switch is config ured[...]

C-81 Troubleshooting DNS Resolver Note that if the target host is in a domain other than the domain configured on the switch, then: ■ The host’ s domain must be reachabl e from the switch . This requires that the DNS server for the switch must be able to communicate with the DNS serv er(s) in the path to the domain in w hich the targ et host op[...]

C-82 Troubleshooting DNS Resolver c. The domain name for an accessible domain in which there are hosts you want to reach with a DNS-c ompatible command. (This is the domain s uffix in the f ully qualif ied domain name for a given host operating in the select ed domain. Refer to “T erminology” on page C- 79.) Note that if a domain suffix is n ot[...]

C-83 Troubleshooting DNS Resolver Example Using DNS Names wi th Ping and T raceroute In the network illu strated in Figure C-27, the switch at 10.28.192 .1 is config- ured to use DNS names for DN S- compatible commands in the pubs.outdoors . com domain. The DNS server has be en configured to assign the host name docservr to the IP address used by t[...]

C-84 Troubleshooting DNS Resolver Configuring switch “A” with the domai n 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 do main to perform ping and traceroute actions on the devic es in the domain. T o summarize: W ith the above alrea dy configured, th e following com[...]

C-85 Troubleshooting DNS Resolver As mentioned under “Basic Operation” on page C-80, if the DNS entry config- ured in the switch does not include the domain suffi x for the desired ta rget, then you must use the target host’ s fully qualified dom ain name with DN S- compatible commands. For example, using the docume nt server in Fi gure C- 27[...]
