2.1.11. ip default-gateway
Syntax
ip default-gateway A.B.C.D
no ip default-gateway
Parameter
A.B.C.D Specify default gateway IPv4 address for switch
Default
Default IP address of default gateway is 192.168.1.254.
Mode
Global Configuration
Usage
Use ip default-gateway command to modify default gateway
address. And use “no ip default-gateway” to restore default
gateway address to factory default.
Example
This example shows how to modify the ipv4 address of the switch.
Switch(config)# ip default-gateway 192.168.1.100
This example shows how to show current ipv4 default gateway of the switch.
Switch# show ip
IP Address: 192.168.1.1
Subnet Netmask: 255.255.255.0
Default Gateway: 192.168.1.100
