[cisco-voip] The CMM and SPAN

[Linsemier, Matthew]

Ryan,

 

As a alternative, have you tried spanning one of the VLAN ports that
your phones are on (another method that can be used for
recording/monitoring)?  We utilize CMM's as well and if I remember I had
a similar issue back in the day when I initially tried configuring
spanning of these ports.  I ended up segmenting all of the phones
utilized for our CAC (where we needed recording/montiroing) into their
own VLAN and then used RSPAN to span both directions back to the IPCC
Express server. You could do this as a test to make sure that it is
definitely a CMM issue and not something else

 

That being said, if you have SMARTNet contract on IPCC Express, 4.x
doesn't require the spanning of any ports if you are using Agent
Desktop.

The other day I encountered what appears to be a bug, but I could not
locate anything in the bug navigator. 

Trying to SPAN the backplane port of a CMM module in a Cat 6500 with
Sup720, for the purposes of IPCCx recording/monitoring (in 3.x).  The
SPAN configuration is very straight forward (I believe) but I found that
when I SPAN both directions I receive only the transmit packets,
resulting in only recording one side of the conversation.  I confirmed
this by changing the SPAN source to receive only and NO packets were
mirrored whatsoever.  From what I can tell, it seems I can't SPAN
packets coming from the CMM.

Are there any SPAN/CMM caveats I should be aware of, or does this really
sound like a defect? I didn't see anything in release notes or guides.

Thanks, 
Ryan
