Question about Cat3560,,,,

I am confronting Cisco 3560 switch.

My problem is that on 3560 I can't find the "wrr-queue" serise command which works fine on 3550 switch.

If anyone knows this what specific command works like the former one, Please let me know.

Your line will be very appreciated.

Cheers,

Re: Question about Cat3560,,,,

Hi ,

The QOS configuration on the 3560 is different from the 3550 which is why the

following commands are not accepted.

wrr-queue bandwidth 20 1 80 1 ----> egress bandwidth allocation

wrr-queue min-reserve 1 5 -----> minimum reserve level

wrr-queue min-reserve 2 6

wrr-queue min-reserve 3 7

wrr-queue min-reserve 4 8

wrr-queue cos-map 1 0 1 2 4 -----> cos to queue mapping

1. The first line "egress bandwidth allocation" is done via the following command:

"mls qos queue-set output qset-id buffers allocation1 ... allocation4"

2. The "minimum-reserve level" does not exist on the 3560. The 3560 uses queue thresholds

with WRED instead.

3. The "cos to queue mapping" is done via the following command:

"mls qos srr-queue output cos-map queue queue-id threshold threshold-id cos1...cos8"

In a nutshell, the 3560 QoS capabilities is a lot more granular and advance than the 3550.

I recommend you going through the following document .

Hope it helps you.
