This section describes commands used to configure IP addresses for VLAN
interfaces on the switch.
ip address This command sets the IPv4 address for the currently selected VLAN
interface. Use the no form to restore the default IP address.
SYNTAX
ip address {ip-address netmask [secondary]
[default-gateway ip-address] | bootp | dhcp}
no ip address [ip-address netmask [secondary] | dhcp]
ip-address - IP address
netmask - Network mask for the associated IP subnet. This mask
identifies the host address bits used for routing to specific subnets.
The network mask can be either in the traditional format
xxx.xxx.xxx.xxx or use classless format with the range /5 to /32.
For example the subnet 255.255.224.0 would be /19.
secondary - Specifies a secondary IP address.
default-gateway - The default gateway. (Refer to the ip default-
gateway command which provides the same function.)
bootp - Obtains IP address from BOOTP.
dhcp - Obtains IP address from DHCP.
