3550 V 3650

Steve Ashton

We have a 3550 with qos configured as follows:

interface FastEthernet0/47
description voice
switchport access vlan 13
switchport mode access
no ip address
mls qos cos 5
mls qos trust cos
wrr-queue cos-map 1 0 1
wrr-queue cos-map 2 2 3
wrr-queue cos-map 3 4
wrr-queue cos-map 4 5 6 7
priority-queue out

We have a new 3560G which only accepts the following commands.

interface GigabitEthernet0/47
description Voice
switchport access vlan 25
switchport mode access
priority-queue out
mls qos cos 5
mls qos trust cos
spanning-tree portfast

My question is what are the appropiate configuration commands for the 3560G?

Thanks.

Hi,

WRR (Weighted Round Robin) is not available on the 3560 series switches, as those switches are supporting SRR (Shaped Round Robin) queuing and scheduling.

You can use the mls qos srr-queue {input | output} cos-map global configuration command on the 3560 switch.

Please refer to the Catalyst 3560 Switches - Configuring QoS documentation on the link below:

Best regards,

Andras
