What would this config actually do (srr-queue)

I have seen this interface configuration around on a few switches in my network.

interface GigabitEthernet1/0/10

switchport access vlan 2

srr-queue bandwidth shape 0 0 0 0

What would the srr-queue command do here?  there is nothing else on the interface.

I think it pretty much does nothing, but just not 100% sure.

thanks

Hi,

This command is used for shaping the traffic. Do you have QOS enabled on the switch?

Issue show mls qos, to check if you have enabled it.

Here you have SRR shape weight to zero for all queues so effectively no shaping is applied. For example if you had something like srr-queue bandwidth shape 30 0 0 0, it would have restricted the first queue to “1/30” of the interface bandwidth (which is approximately 3.3Mbps for 100Mbps interface and approximately 330Kbps for a 10Mbps interface) and rest of the queues would have shared rest of the interface bandwidth.

For more details you may go through the following:
