Well I am definitely a bit frustrated with this one.
My setup is a Catalyst (3560 C3560-IPBASE-M), Version 12.2(35)SE5,
I have a cisco phone with a PC behind it on port gi 0/40
switchport access vlan 5
switchport voice vlan 105
Phone gets 105.x ip and PC gets 5.x ip. All is working well.
I am trying to sniff this traffic to ensure vlan tagging and QOS markings by using SPAN.
monitor session 1 source int gi 0/40
monitor session 1 destination int gi 0/3 encapsulation replicate
Can someone confirm that this is the correct config for this ?
Wireshark shows me entire phone conversation but I cannot see any 802.1q tagging..
I also tried to sniff int gi 0/49 as it is my dot1q trunk back to the core and I still cant see any vlan tagging..
Hoping someone can help me out on this one. I have read thru the docs and this should be a easy...
