Step Description
18.
Repeat Step 2 – 17 as necessary to protect other VLANs. In this configuration, the steps were
repeated for VLAN 53.
4. Configure Cisco Catalyst 3560
This section describes the steps on the Cisco Catalyst 3560 for configuring the VLAN mirror, the
two ports connected to the Mirage Networks CounterPoint C-245, and the port connected to the
Avaya P333T-PWR. The steps assumed that the VLANs and routing among VLANs have
already been configured on the Catalyst 3560.
Step Description
1.
From the Catalyst 3560 Command Line Interface (CLI), assign the protected VLANs (53 and
100 in the sample configuration) to the two ports connected to the CounterPoint C-245, and
configure the ports as trunk ports with 802.1q encapsulation.

switchport trunk encapsulation dot1q
switchport trunk allowed vlan 53,100
switchport mode trunk
no ip address
no mdix auto
!
interface FastEthernet0/22
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 53,100
switchport mode trunk
no ip address
no mdix auto
2.
Configure a monitor session to mirror all VLAN traffic from the protected VLANs to the port in
Step 1 connected to the “Reader” port on the CounterPoint C-245.
monitor session 1 source vlan 53 , 100
monitor session 1 destination interface Fa0/22 encapsulation replicate
3.
Assign VLAN 100 to the port connected to the Avaya P333T-PWR, and configure the port as a
trunk port with 802.1q encapsulation.
interface FastEthernet0/23
