IP Addressing Commands 299
Default Configuration
No default gateway is defined.
Command Mode
Global Configuration mode
User Guidelines
A static IP address must be configured using the ip address command before setting the default
gateway. The default gateway should reside on the subnet defined by the ip address command.
NOTE: For management traffic forwarding decisions, a default-route configured on the switch (CLI, Web,
SNMP, or learned via routing protocol such as OSPF), takes precedence over the ip default-gateway
setting.
Example
The following example defines ip default-gateway as 10.240.4.1.
console(config)#ip default-gateway 10.240.4.1
