8.3 Typical Configuration Example
Scenario Four PCs as shown in the above figure connect to port 5, 7, 9, 11 of switch, all the four
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 blackhole address 00-01-11-11-11-11 vlan 1
2.Set the static mapping relationship for PC2 and PC3 to port 7 and port 9, respectively.
Switch(Config)#mac-address-table static address 00-01-22-22-22-22 vlan 1 interface ethernet 0/0/7
Switch(Config)#mac-address-table static address 00-01-33-33-33-33 vlan 1 interface ethernet 0/0/9
8.4 Troubleshooting
8.4.1 Monitor and Debug Command
8.4.1.1 show mac-address-table
Command show mac-address-table [static|aging-time|blackhole|count] [address <mac-addr>]
[vlan <vlan-id>] [interface <interface-name>]
Parameter static entry; aging-time address aging time; blackhole filtering entry; count address
counter; entry’s MAC address; entry’s VLAN number;
entry’s interface name
Command mode Admin mode
