Configuring Advanced Threat Protection
Dynamic IP Lockdown
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.
Note 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.
