Interface Gigabit 3/1

Switchport trunk encapsulation dot1q
Switchport trunk allowed vlan 101-102
Example 2
Let us assume that interface Gigabit Ethernet 6/1 is a trunk port and belongs to VLANs 20, 300-301, and
400. The following example shows how to apply policy-map p1 for traffic in VLANs 20 and 400 and
policy map p2 to traffic in VLANs 300 through 301:
Switch# configure terminal
Switch(config)# interface gigabitethernet 6/1
Switch(config-if)# vlan-range 20,400
Switch(config-if-vlan-range)# service-policy input p1
Switch(config-if-vlan-range)# exit
Switch(config-if)# vlan-range 300-301
Switch(config-if-vlan-range)# service-policy output p2
Switch(config-if-vlan-range)# end
Switch#
Example 3
The following command shows how to display policy-map statistics on VLAN 20 configured on Gigabit
Ethernet interface 6/1:
Switch# show policy-map interface gigabitEthernet 6/1 vlan 20
GigabitEthernet6/1 vlan 20
Service-policy input: p1
