Configuring a Default Gateway

The switch uses the default gateway only when it is not configured with a routing protocol.
Note
Configure a default gateway to send data to subnets other than its own when the switch is not configured
with a routing protocol. The default gateway must be the IP address of an interface on a router that is
directly connected to the switch.
To configure a default gateway, perform this task:
Command
Step 1
Switch(config)# ip default-gateway IP-address
Step 2
Switch# show ip route
This example shows how to configure a default gateway and how to verify the configuration:
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# ip default-gateway 172.20.52.35
Switch(config)# end
3d17h: %SYS-5-CONFIG_I: Configured from console by console
Switch# show ip route
Default gateway is 172.20.52.35
Host
ICMP redirect cache is empty

Configuring a Static Route
If your Telnet station or SNMP network management workstation is on a different network from your
switch and a routing protocol has not been configured, you might need to add a static routing table entry
for the network where your end station is located.
