Since I didn't see QoS section in the forum I am posting here.
I have one Cisco 3560 connected to a Cisco 2960. We have all our IP hard phones (Avaya)connected to a Cisco 2960 switch. When I check the option on the phones I see the phone marks the traffic with DSCP 46 for Audio and DSCP 34 for signaling. I implemented the following access list to the Cisco 3560 (the switch above the 2960) to capture the marking from the phones:
Extended IP access list 102
10 permit ip 192.168.102.0 0.0.1.255 any dscp ef
20 permit ip 192.168.102.0 0.0.1.255 any dscp af41
30 permit ip 192.168.102.0 0.0.1.255 any dscp af31
40 permit ip any any (15 matches)
As you may see I am catching only any any conversation matching. Is it possible Cisco 2960 removing the DSCP marking from the phones on their way to the upper switch 3560 Switch?
Thanks in advance!
