help needed for 802.1p

[solo]

I´ve been trying to configure a rule in order to set a 802.p of 7 to all traffic on one vlan. In my lab I´m using vlan 40 and these are the configs that i´ve tested


qos enable
qos trust ports
policicy condition VoIP source vlan 40
policy action set 802.1p 7
policy rule voip condition VoIP action set
qos apply


qos enable
qos trust ports
policicy condition VoIP source ip 10.10.10.0 mask 255.255.255.0
policy action set 802.1p 7
policy rule voip condition VoIP action set
qos apply

Where 10.10.10.0 is the segment of the vlan 40

also,

qos enable
qos trust ports
policicy condition VoIP source port 1/13
policy action set 802.1p 7
policy rule voip condition VoIP action set
qos apply

where port 1/13 is the port of an ipphone.

I,ve been snnifering the output of the links and I can see the priority.

Does anyone has an idea of what I´ve to do in order to make it work???

hi,
do you see the 802.1q-tag with sniffer? Most of 1G-NICs I have tested don't see this with wireshark. I use an old 100M-USB-NIC for sniffering of q-tags.
Your config is okey. If you set the prio with a policy you don't need trust the incomming prio.
So you can delete the fist two commands (qos is enabled by default).

hello

did you use 802.1Q between your phone and port of the switch ? if no there is no 802.1p on the outgoing traffic
I have the same pb, wireshark don't show 802.1q tag (I use a fluke to see them)
As silvio said you are okay with your config

Hi, all

the problem is that the OS have a the default trust for ipphones, so any policy that you configure won´t be applied unless that you run the command qos no phones,
I tried after that command and priority was gorking.

ok thanks for this clarification.

[silvio]

this is right for Alcatel-phones (mac-depending). Thats why I prefer to set prio direct in the phone (at Alcatel in the pbx) and trust the incomming prio.
