ip address

Syntax

ip address <IPV4-ADDR>/<MASK> [secondary]

no ip address <IPV4-ADDR>/<MASK> [secondary]

Description

Sets an IPv4 address on the interface. Configure the interface as layer 3 using the routing command. Two IPv4 addresses can be configured per interface.

The no form of this command removes the IPv4 address from the interface.

Command context

config-if

Parameters

<IPV4-ADDR>: Specifies an IP address in IPv4 format (x.x.x.x), where x is a decimal number from 0 to 255. You can remove leading zeros. For example, the address 192.169.005.100 becomes 192.168.5.100.
<MASK>: Specifies the number of bits in the address mask in CIDR format (x), where x is a decimal number from 0 to 128.
secondary: Specifies a secondary IP address.

Examples

Setting an IP address on interface 1/1/1 to 198.51.100.1 with a mask of 24 bits:

switch(config)# interface 1/1/1
switch(config-if)# ip address 198.51.100.1/24

Removing the IP address 198.51.100.1 with a mask of 24 bits from interface 1/1/1:

switch(config)# interface 1/1/1
switch(config-if)# no ip address 198.51.100.1/24
