6.9.4 Example for Configuring a MAC Address Learning Rule in a
VLAN
Networking Requirements
As shown in Figure 6-4, Ethernet2/0/1 and Ethernet2/0/2 of the Router are connected to LSWs.
The LSWs are connected to users, including a few IP phone users and many computer users. IP
phone users are in VLAN 100, and computer users are in VLAN 200. To prevent MAC address
attacks and save MAC address table space, configure a rule to limit the number of MAC
addresses learned in VLAN 200.
