SPAN & RSPAN across 2 switches

[Network TSC Vuitton]

Hi,

We have two 2960X switches in a call center and two call recording servers connected to port  40 in both switches. (switch is not a stack).

They need to monitor voice vlan of both switches in to both recording servers.
(SW1 & SW2 voice vlan traffic mirror to port 40 of SW1 & SW2.)

Can somebody help us with any idea? Thank you very much.

Hi

I think you could use 2 different remote vlans

SWITCH 1

vlan 10
name voice vlan

vlan 255
name SWITCH1
remote-span

vlan 256
name SWITCH2
remote-span

monitor session 1 source vlan 10 both
monitor session 1 destination interface g1/40

monitor session 2 source vlan 10 both
monitor session 2 destination remote vlan 255

monitor session 3 source remote vlan 256
monitor session 3 destination interface g1/40

SWITCH 2

vlan 10
name voice vlan

vlan 255
name SWITCH1
remote-span

vlan 256
name SWITCH2
remote-span

monitor session 1 source vlan 10 both
monitor session 1 destination interface g1/40

monitor session 2 source vlan 10 both
monitor session 2 destination remote vlan 256

monitor session 3 source remote vlan 255
monitor session 3 destination interface g1/40

* If you have applying any restriction over the trunk interfaces you must add these remote span vlans on both trunk interfaces.

To be honest I have no implemented this kind of scenario with 2 recording systems receiving the same traffic, but this configuration could be useful, also verify if this switch models support more than 2 monitor sessions.

Yes that is their requirement.

Hi Julio,

I tried the same method, but there is an error when I try to use same destination port for 2 sessions. Cisco does not allow it. I can't think of other possible way.
