Hello, I have this scenario, hope somebody can help me.
Core switch <-----------> IP Tel Switch <------------>phones
1 2 3
.
.
.
.
<-----------> ........... ............
xN xN
All the switches are 3750-v2 and phones are from cisco. Only one core.
This is the current behaviour:
2 trust cos from 3
1 trust cos on trunk from 2
I configured intervlan routing on 1. Do i need to trust dscp on both the interface vlans on 2 and 1?
thanks for your precious help
Lorenz
