Hi, gents.
Please, could you explain me how it should works and what I did not right.
I am trying to figure out the behavior of qos implementation on Cisco 3750
switch.
That's my topology:
Fa0/0 gi1/0/2 gig1/0/23
[router2]------------------[switch2]--------------------[bsd-box]
.2 173.1.0.0/24
.254
I have configured trunks between router2&switch2 and switch2&bsd-box.
I have configured on port gig1/0/2 "mls qos trust cos" and globally enabled
"mls qos".
From router2 I have been sending frames with cos 4 toward bsd-box and I got
frames with cos 0 and IP packets with 0x20 on it.
It's sounds like mls qos mapping works, but why I got frames with cos value
equal zero?
On bsd-box I am using wireshark as sniffer program.
Kindly,
Vitalii Braichuk
