[cisco-voip] Fwd: 7912

[Ryan Ratliff]

Correct only with the 7912G.  A packet capture from a span port of  
the PC is a good way to see what is causing the flood (multicast,  
virus, broadcast storm, etc) .

Thanks Ryan,

If I understand you correctly the Issue is with 7912G and not with  
7912G-A , I will check the model of my phones and get back to you, I  
have had these deployed over several sites but got complaints from  
only one remote site.

What is the model number of the 7912 (cp-7912G vs cp-7912G-A)?


The older 7912 models were susceptible to excessive unicast and  
broadcast traffic on the PC port (data vlan) which would cause the  
phone to drop packets.  This could appear as poor audio quality while  
on calls or random resets of the phone.  This is due to the software  
switch implemented in the original phones.  The later phones have a  
hardware switch that corrects this problem.


If you don't have a 7912-A then open a TAC SR and RMA the phone.  You  
will receive a 7912A in return.
