Command or Action

switch# configure terminal

switch(config)# ip host name

address1 [address2... address6]

switch(config)# ip

domain-name name [use-vrf

vrf-name]

switch(config)# ip dns

source-interface [loopback X

different interface]

switch(config)# ip domain-list

name [use-vrf vrf-name]

Purpose

Enters global configuration mode.

Defines up to six static hostname-to-address mappings in the

hostname cache. The address can be either an IPv4 address or an

IPv6 address.

(Optional)

Defines the default domain name that Cisco NX-OS uses to

complete unqualified host names. You can optionally define a

VRF that Cisco NX-OS uses to resolve this domain name if it

cannot be resolved in the VRF that you configured this domain

name under.

Cisco NX-OS appends the default domain name to any hostname

that does not contain a complete domain name before starting a

domain-name lookup.

use-vrf is used as a DNS query supposed to be sending on a

different VRF and listening for the reply on a different VRF.

Example: DNS query is sent over VRF RED while the response

should come on VRF Default.

Defines what will be the source IP for the DNS Query which will

be sent out. When DNS server tries to answer back, it will use the

Loopback0 as the destination and there should be a valid return

route.

(Optional)

Defines additional domain names that Cisco NX-OS can use to

complete unqualified hostnames. You can optionally define a VRF

that Cisco NX-OS uses to resolve these domain names if they

cannot be resolved in the VRF that you configured this domain

name under.

Cisco NX-OS uses each entry in the domain list to append that

domain name to any hostname that does not contain a complete

domain name before starting a domain-name lookup. Cisco NX-OS
