9-4 ip address
This command is used to set a primary or secondary IPv4 address for an interface, or acquire an IP
address on an interface from the DHCP. Use the no command to remove the configuration of an IP
address or disable DHCP on the interface.
ip address {IP-ADDRESS SUBNET-MASK [secondary] | dhcp}
no ip address [IP-ADDRESS SUBNET-MASK | dhcp]
Parameters
IP-ADDRESS
Specifies the IP address.
SUBNET-MASK
Specifies the subnet mask for the associated IP address.
secondary
(Optional) Specifies that the configured address is a secondary IP
address. If this keyword is not specified, the configured address is the
primary IP address.
dhcp
Specifies to acquire an IP address configuration on an interface from
the DHCP protocol.
Default
The default IP address for VLAN 1 is 10.90.90.90/8.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
The IPv4 address of an interface can be either manually assigned by the user or dynamically assigned by
the DHCP server. For manual assignment, the user can assign multiple networks to a VLAN, each with an
IP address. Among these multiple IP addresses, one of them must be the primary IP address and the rest
are secondary IP address. The primary address will be used as the source IP address for SNMP trap
messages or SYSLOG messages that are sent out from the interface. Use the no ip address command
to delete the configured IP address entry.
Example
This example shows how to set 10.108.1.27 is the primary address and 192.31.7.17 and 192.31.8.17 are
secondary addresses for VLAN 100.
Switch# configure terminal
Switch(config)# interface vlan100
Switch(config-if)# ip address 10.108.1.27 255.255.255.0
Switch(config-if)# ip address 192.31.7.17 255.255.255.0 secondary
Switch(config-if)# ip address 192.31.8.17 255.255.255.0 secondary
Switch(config-if)#
