[cisco-voip] The CMM and SPAN

[Voll, Scott]

Is the layer three vlan interface on the Cat 6509?  If so, try to SPAN
the layer 3 interface rather then the CMM port.

 

What version of IOS are you using on the 65xx and the CMM?

 

I'm using 12.2(18)SXF4 and 12.4(7a) without problem

 

SPAN Config:

 

Vlan 102 is my Core Voice VLAN and 202 is my RSPAN

 

monitor session 2 source vlan 102

monitor session 2 destination remote vlan 202

monitor session 4 destination interface Fa3/44 <-- IPCCx Monitor server

monitor session 4 source remote vlan 202

 

 

Sh mon sess all

 

Session 2

---------

Type                   : Remote Source Session

Source VLANs           :

    Both               : 102

Destination RSPAN VLAN : 202

 

Session 4

---------

Type                   : Remote Destination Session

Source RSPAN VLAN      : 202

Destination Ports      : Fa3/44

PS.  All your agents are on the same vlan as your IPCCx server, right?

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
