DNS Resolver

c. The domain name for an accessible domain in which there are hosts

you want to reach with a DNS-compatible command. (This is the
domain suffix in the fully qualified domain name for a given host
operating in the selected domain. Refer to “Terminology” on page C­
88
.) Note that if a domain suffix is not configured, fully qualified
domain names can be used to resolve DNS-compatible commands.

d. the host names assigned to target IP addresses in the DNS server for

the specified domain

2. Use the data from steps 1a through 1c to configure the DNS entry on the

switch.

3. Use a DNS-compatible command with the host name to reach the target

devices.

Configuring a DNS Entry

The switch allows up to three DNS server entries (IP addresses for DNS

servers). One domain suffix can also be configured to support resolution of

DNS names in that domain by using a host name only. Including the domain

suffix enables the use of DNS-compatible commands with a target’s host name

instead of the target’s fully qualified domain name.

Syntax: [no] ip dns server-address priority < 1 - 3 > < ip-addr >

Configures the access priority and IP address of a DNS server
accessible to the switch. These settings specify:
• the relative priority of the DNS server when multiple servers

are configured

• the IP address of the DNS server

These settings must be configured before a DNS-compatible
command can be executed with host name criteria.
The switch supports three prioritized DNS server entries.
Configuring another IP address for a priority that has already
been assigned to an IP address is not allowed. To replace one
IP address at a given priority level with another address
having the same priority, you must first use the

no form of the

command to remove the unwanted address. Also, only one
instance of a given server address is allowed in the server list.
Attempting to enter a duplicate of an existing entry at a
different priority level is not allowed

. To change the priority of

an existing server address, use the

no form of the command to

remove the entry, then re-enter the address with the new
priority.
The

no form of the command replaces the configured IP address

with the null setting. (Default: null)
