Hi
This may be a bit of a long shot but I'm having some trouble using port monitor/mirror on a HP A5120 switch stack and was hoping someone here might be able to offer some advice.
We have a Mitel PBX connected to the stack which our IP phones connect to and this all works fine. I've been asked to mirror the port the PBX is in to a port where we have a call recorder connected so it can pick up and record SIP traffic. As far as i can see the port mirroring is set up correctly - its a pretty basic 1 monitor 1 mirror setup and wireshark on the call recorder shows the mirror is working. The problem i have is that when i plug anything (call recorder or even just my laptop) into the mirror port and make test phone calls, none of them have any audio with the occasional "insufficient bandwidth" message. I unplug the device from the mirror port and they work fine again.
I realise this could be an issue with the PBX but as it works fine without the mirrored port i believe it's a switch bandwidth issue, has anybody come anything like this before when using a mirrored port?
Thanks
Carter
