PCs belong to the default VLAN1. As required by the network environment, dynamic learning

is enabled. PC1 holds sensitive data and can not be accessed by any other PC that is in

another physical segment; PC2 and PC3 have static mapping set to port 7 and port 9,

respectively.

The configuration steps are listed below:

1. Set the MAC address 00-01-11-11-11-11 of PC1 as a filter address.

Switch(config)#mac-address-table static 00-01-11-11-11-11 discard vlan 1.

2.Set the static mapping relationship for PC2 and PC3 to port 7 and port 9, respectively.
