is 7960 really a switch?

[bob.anderson]

I thought the 7960 phone was a 3 port switch

when i use sniffer on the pc attached to the

phone i can see the rtp streams from the telephone

conversation, I did not expect to see this as

i am using a seperate voice and data vlans.

I tried this on a cat 3524 and a cat 6000, with

the same results. If sniffer is set to look at

hardware address i can see the rtp streams

If it is set to look at ip addresses i do not

capture rtp streams. can anyone explain why this

is?

thanks

This came from Cisco.

The phone has a three port switch (100 uplink, 10 internal, 100 PC port), but it is inside of an embedded device and is customized for the task. The ports are switched, but the phone traffic is purposely replicated to the PC port. Interestingly enough this was done so it would be easy to attach a sniffer to the PC port to troubleshoot any problems that might be occurring between the phone and other hosts. This solution does not require a hub or to span a port on a production switch to get a sniffer trace
