Hi guys, I don't know much about SPAN so please advise me if i've posted in the wrong section.
Basically we have a voice recorder that records our VOIP traffic but we think the SPAN has been set up wrong. I'll try explain how it works.
VOIP Handsets - VLAN 30
VOIP Call Servers - VLAN 31
We have a voice recording server with 2 SPAN ports for redundancy, one is plugged into a 6500 Catalyst switch which works fine and monitors traffic on vlan 30 and forwards it to the voice recorder but then we have the other plugged into a 3560 switch and this is only recording 1 side of the conversation.
We have 2 Avaya Call Server LSP's, 1 in 1 building and 1 in our main building. When calls come through to the LSP in our building it records both sides of the conversation and we think this is because the routing is taking place through the 6500 catalyst switch. When they come into the LSP in the other building and ultimately through span port 2 which is connected to the 3560 it only records 1 side. The config we have for SPAN port 2 is the following:
interface GigabitEthernet0/1
description 2nd SPAN Port for eutee-vrec1p
switchport access vlan 31
switchport mode access
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
queue-set 2 priority-queue out
mls qos trust cos
auto qos voip trust
spanning-tree portfast
service-policy input VOIP
The monitor session config for this switch is as following:
monitor session 1 source vlan 30
monitor session 1 destination interface Gi0/1
When I do a show monitor session 1 we get the following:
Session 1
---------
Type : Local Session
Source VLANs :
Both : 30
Destination Ports : Gi0/17
Encapsulation : Native
Ingress : Disabled
We tried turning the ingress on but still the same. The minute we turn the span on aswell and run wireshark all traffic stops on the port. If i havent made any sense please do let me know.
Many Thanks
