Configuring Port Security on Trunk Ports
Figure 55-2 Trunk Port Security
You can configure various port security related parameters on a per-port per-VLAN basis.
Note The steps involved in configuring port security parameters is similar to those for access ports. In addition
to those steps, the following per-port per-VLAN configuration steps are supported for trunk ports.
To configure port security related parameters on a per-VLAN per-port basis, perform this task:
SVI 2 SV1 3
5/45/35/25/1
Metro
Layer 2 switch
Access port in VLAN 2 Access port in VLAN 3

logical interface.
Step 2
Switch(config-if)# switchport trunk encapsulation
dot1q
Sets the trunk encapsulation format to 802.1Q.
Step 3
Switch(config-if)# switchport mode trunk
