Device: IPS 4240
MOde: all 4 interfaces on Promiscuous
Objective: To monitor 4 different vlans namely vlan 10,20,30,40 across the network.
There are 8 switches on my network with vlan 10 - 40 info (vtp trunk)
How do i configure SPAN on VLANs that exist on all my access switches
I tried configuring on the access switch where the IPS interfaces are connected to.
monitor session 1 source vlan 10 , 20 , 30, 40
monitor session 1 destination interface Gi0/1 - 4
Did a mass ping from vlan 10 to its gateway
Checked my IPS interfaces status, i seem to be receiving packets on all 4 interfaces. Shouldnt i be receiving packets on the correct IPS interfaces that the vlan is destined?
