monitor session 1 source vlan (lost packets at destination interface)
We have 2 6513 switches with SUP720/PFC3A and various POE modules and a 6748-GE-TX facing our servers. Additionally, we have a 4Gbps portchannel trunk interconnecting the switches. We have approximately 300 Nortel IP 1140e phones in use between the two switches.
For the purpose of call recording, we've attempted to mirror the voice vlan using various approaches and have been met with limited success. We mirrored the VLAN using tx, rx, and both. When using both we appear to get duplicate packets at the destination interface.
We seem to lose packets completely going in one direction or another for a given call. Has anyone experienced a situation such as this where packets are lost before they get to the destination interface?
The call quality is perfect between the call server and the telephone. We considered capturing the traffic using VACL capture... but I believe that the layer 2 address would be lost before the traffic ever saw the destination interface... is this accurate?

Just looking for some clarification here.
1. Are you losing one direction of a phone call only in the capture - or are live phone calls impacted with this issue?
2. Are all phones in question existing solely in VLAN 24? Or is there any inter-VLAN calling happening?
With regard to MAC addresses being lost with VACL capture method - I have never noticed this happening. That being said I don't have an active VACL anywhere that I can confirm this for you. I can think of no reason the VACL would lose the MAC's though.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
