Adding a Static Binding
To add the static configuration of an IP-to-MAC binding for a port to the lease database, enter the
ip
source-binding
command at the global configuration level. Use the
no
form of the command to remove
the IP-to-MAC binding from the database.
N o t e
Note that the
ip source-binding
command 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.
