ip-secondary-address

This command manages secondary network addresses for the VLAN interface.

Syntax

Add a secondary address: ip-secondary-address address
Remove a secondary address: no ip-secondary-address address
Remove all secondary addresses: no ip-secondary-address

Parameters

address

Specifies the IP address and netmask. The netmask is in CIDR format and is the integer that assigns the prefix length.

For version 4, the prefix length can be in the range of 0 through 32.
For version 6, the prefix length can be in the range of 0 through 128.

Guidelines

The ip-secondary-address command manages secondary network addresses for the current interface. The network address is the IP address and its subnet mask. A secondary IP address is a bind address. The secondary IP address is used only as a source IP address when it responds to incoming traffic to the secondary IP address.

To create the primary IP address, use the ip-address command.

To remove secondary IP addresses, use the no ip-secondary-address command.

This command is meaningful except when you use the ip-config-mode command for autoconfiguration with DHCP or SLAAC.

Examples

Add 192.168.7.6/27 as a secondary IP address to the interface.
```
# ip-secondary-address 192.168.7.6/27
```
Remove 192.168.7.6/27 as a secondary IP address.
```
# no ip-secondary-address 192.168.7.6/27
```
Remove all secondary IP addresses.
```
# no ip-secondary-address
```
