ip address

Syntax

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

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

Description

Sets an IPv4 address for the current layer 3 interface.

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

Command context

config-if

config-loopback-if

config-if-vlan

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.

Authority

Administrators or local user group members with execution rights for this command.

Examples

On the 6400 Switch Series, interface identification differs.

Creating a layer 3 interface setting its IP address to 192.168.100.1 with a mask of 24 bits. 

switch(config)# interface 1/1/1
switch(config-if)# routing
switch(config-if)# ip address 192.168.100.1/24
Assigning the IP address 192.168.20.1 with a mask of 24 bits to loopback interface 1: 
switch(config)# interface loopback 1
switch(config-loopback-if)# routing
switch(config-loopback-if)# ip address 192.168.20.1/24
Assigning the IP address 192.168.199.1 with a mask of 24 bits to interface VLAN 10: 
switch(config)# interface vlan 10
switch(config-loopback-if)# ip address 192.168.199.1/24
Removing the IP address 192.168.199.1 with a mask of 24 bits from interface VLAN 10: 
switch(config)# interface vlan 10
switch(config-loopback-if)# no ip address 192.168.199.1/24
