SPAN Port Limitations

[mparella]

I have a Cat 4510 currently configured with 2 SPAN Port monitor sessions each monitoring both TX and RX traffic on my voice VLAN. I need to add an additional session to see all of this traffic and have it sent to a box running my VoIP Monitoring software. Unfortunately I can not add any addional TX/RX sessions b/c of device limitations. Any ideas on how to get past/workaround these limitations for SPAN Port sessions?

Thanks!

Can we moniter both tx and rx traffic on an etire voice vlan. I think we can moniter ony re traffic on a vlan.

You defintely can monitor both TX and RX traffic. You can actually go as far as to monitor multiple VLANS both TX/RX.

I am sure the limitation is b/c of resources on the box, but I can't believe there isn't another workaround.
