I am trying to set up a new voice recording system. We currenlty use the 3750 24 port TS with PoE which has 24 ports of 100Mbps and 2 Gig ports.
My current config for voice recording uses port Fa1/0/24 as the destination for the SPAN session.
monitor session 1 source vlan 234
monitor session 1 destination interface fa1/0/24
This has worked very well.
With the new system we want to use a gigabit port for the destination.
If have set up
monitor session 2 source vlan 234
monitor session 2 destination interface gi1/0/2
In theory I should see exactly the same traffic on these two SPAN sessions if I understand the docs correctly.
However, I don't. I am not seeing any of the vlan 234 traffic on the gigiabit port, only EIGRP, and other sundry connection related traffic.
No data traffic at all however.
What am I missing? Can the gig ports be used as span destinations?
