Cisco SG 300 QoS to Cisco Catalyst 2960x and Cisco Catalyst 9200

[Ulli Popp]

Hello, everyone,

I'm new to the forum and have a problem where I'm just stuck and hope for your help.

We have several Cisco SG 300 switches in use.

Now we want to switch to Cisco Catalyst 2960x and Cisco Catalyst 9200 Switches.

We have already transferred the configuration from the Cisco SG 300 to our new Cisco Catalyst 2960x and Cisco Catalyst 9200 switches.

That works without any problems Now I want to set up QoS in the Cisco Catalyst 2960x and Cisco Catalyst 9200 switches.

How can I transfer the QoS configuration from the Cisco SG 300 to the Cisco Catalyst 2960x and Cisco Catalyst 9200 switches.

Here is the configuration of the Cisco SG 300:

qos advanced
qos map dscp queue 46 to 4
qos map dscp queue 56 to 5

How do I configure this in the Cisco Catalyst 2960x and Cisco Catalyst 9200 switches?

I've already read through a few instructions, but I don't know what exactly to conflict.

Can someone show me what I have to configure based on my configuration?

Thanks very much.

Ulli

 - Since you migrate from small business to enterprise switches   , it would be better to take a step back and ask : what is your QoS policy 2) What where those commands intended to do on the SG 300 ? Once you know that review these documents below and act accordingly :

Hello,

This is a special Protocol.

The QoS DSCP Decimal 56, DSCP Label CS7 has the second value in the QoS DSCP Decimal 46, DSCP Label EF

The point is to prioritize the traffic with the value 56 first and then the value 46.

The rest of the traffic does not need any prioritization.

I've read through the documents and I would configure it like this:

mls qos
mls qos srr-queue output dscp-map queue 2 threshold 1 46 56
mls qos srr-queue output dscp-map queue 3 threshold 2 0 1 2 3 4 5 6 7
mls qos srr-queue output dscp-map queue 3 threshold 2 9 10 11 12 13 14 15 16
mls qos srr-queue output dscp-map queue 3 threshold 2 17 18 19 20 21 22 23 24
mls qos srr-queue output dscp-map queue 3 threshold 2 25 26 27 28 29 30 31 32
mls qos srr-queue output dscp-map queue 3 threshold 2 33 34 35 36 37 38 39 40
mls qos srr-queue output dscp-map queue 3 threshold 2 41 42 43 44 45 47 48 49
mls qos srr-queue output dscp-map queue 3 threshold 2 50 51 52 53 54 55 57 58
mls qos srr-queue output dscp-map queue 3 threshold 2 59 60 61 62 63
!
int range gi1/0/1-12 
mls qos trust dscp
priority-queue out
srr-queue bandwidth share 1 0 60 40

Unfortunately I do not know if this is correct.

Hi there,

does anyone know if that fits?

I don't know any more .....

Thanks very much.
