QoS witch a "Non-Cisco-IP-Phone" on a TRUNK-Port

rnolden · ‎03-12-2007

we have "Non-Cisco-IP-Phones" with Cat3560+PoE and TRUNK-Ports with 2 Vlans(one DATAvlan,one VOICEvlan)

how is it possible to enable QoS (1st step: Classification and Marking) on this TRUNK-Ports with "service-policy input" (with class-map,policy-map)

it seem so, as it doesn't work on a TRUNK ?

there are no matches in ACL (sh access-lists) and POLICY-MAP (sh policy-map interface fastEthernet 0/1)

....any idea....

regards,

Ralf

Here is the link to the full configuration document:

http://www.cisco.com/univercd/cc/td/doc/product/lan/cat3560/12225see/scg/swqos.htm#wp1231446

This command will tell the switch to trust whatever QoS values it recieves on the port and map it to the correct queue.

end

edit your ports, im sure my ports wont match up with yours.

on your interfaces, you have to enable the priority queueing and bandwidth percentage:

interface GigabitEthernet0/1

switchport trunk encapsulation dot1q

switchport mode trunk

service-policy input voice

srr-queue bandwidth share 1 70 25 5

srr-queue bandwidth shape 3 0 0 0

priority-queue out

queues 2,3,4 get 70% 25% and 5% respectively.

queue 1 gets 33% of all available bandwidth.

Allen,

attached is my topology. The IP phones are placed on the access switches.

All access switches are 2960 and the L3 is 3750.

Where should i mark the traffic, on the 2960 or the 3560 and do i need to apply the service policy input to all the ports?
