Command History
Usage Guidelines A static IP source binding entry has an IP address, its associated MAC address, and its associated VLAN
number. The entry is based on the MAC address and the VLAN number. If you modify an entry by
changing only the IP address, the switch updates the entry instead creating a new one.
Examples This example shows how to add a static IP source binding:
Switch(config)# ip source binding 0001.1234.1234 vlan 1 172.20.50.5 interface
gigabitethernet1/0/1
This example shows how to add a static binding and then modify the IP address for it:
Switch(config)# ip source binding 0001.1357.0007 vlan 1 172.20.50.25 interface
gigabitethernet1/0/1
Switch(config)# ip source binding 0001.1357.0007 vlan 1 172.20.50.30 interface
gigabitethernet1/0/1
