Adding a Static BindingTo add the static configuration of an IP-to-MAC binding for a port to the lease database, enter the ip source-bindingcommand at the global configuration level. Use the no form of the command to remove the IP-to-MAC binding from the database.
Syntax: [no] ip source-binding <vlan-id> <ip-address> <mac-address> <port- number>
vlan-idSpecifies a valid VLAN ID number to bind with the specified MAC and IP addresses on the port in the DHCP binding database.
ip-addressSpecifies a valid client IP address to bind with a VLAN and MAC address on the port in the DHCP binding database.
mac-addressSpecifies a valid client MAC address to bind with a VLAN and IP address on the port in the DHCP binding database.
port-numberSpecifies the port number on which the IP-to- MAC address and VLAN binding is configured in the DHCP binding database.
N o t e
Note that the ip source-bindingcommand is the same command used by the Dynamic ARP Protection feature to configure static bindings. The Dynamic ARP Protection and Dynamic IP Lockdown features share a common list of source IP-to-MAC address bindings.
Verifying the Dynamic IP Lockdown Configuration
To display the ports on which dynamic IP lockdown is configured, enter the show ip source-lockdown status command at the global configuration level.
Syntax: show ip source-lockdown status
