Ip Default-Gateway - 3Com 3CRUS2475 Command Reference Manual

ip default-gateway

If the device is configured to obtain its IP address from a DHCP server, it
sends a DHCPDISCOVER message to provide information about itself to
the DHCP server on the network.
If the ip address dhcp command is used with or without the optional
keyword, the DHCP option 12 field (host name option) is included in the
DISCOVER message. By default, the specified DHCP host name is the
globally configured host name of the device. However, the ip address
dhcp hostname host-name command can be used to place a different
host name in the DHCP option 12 field.
The no ip address dhcp command deconfigures any IP address that was
acquired, and sends a DHCPRELEASE message.
Example
The following example acquires an IP address for Ethernet port g16 from
DHCP.
Console(config)# interface ethernet g16
Console(config-if)# ip address dhcp
The ip default-gateway Global Configuration mode command defines
