Switch Management Commands

User Guidelines
This command only applies to routing interfaces. When DHCP is enabled on
a routing interface, the system automatically deletes all manually configured
IPv4 addresses on the interface.
• The command no ip address removes the interface’s primary address
(Manual/DHCP) including the secondary addresses, if configured, and sets
the Interface method to None .
• The command no ip address dhcp removes the interface’s primary address
only if configured through DHCP and sets the interface method to None .
It does not remove a manually configured address.
In addition to leasing an IP address and subnet mask, the DHCP client may
learn the following parameters from a DHCP server:
• The IPv4 address of a default gateway. If the device learns different default
gateways on different interfaces, the system uses the first default gateway
learned. The system installs a default route in the routing table, with the
default gateway’s address as the next hop address. This default route has a
preference of 254.
• The IPv4 address of a DNS server. The DNS client stores each DNS server
address in its server list.
• A domain name. The DNS client stores each domain name in its domain
name list.
Examples
To enable DHCPv4 on vlan 2:
console#config
console(config)#interface vlan 2
console(config-if-vlan2)#ip address dhcp

Use the ip default-gateway command to configure a default gateway (router).
