I have the following config on a Cisco router that is being used as a test lab for our server team. We are simulating some of our WAN connections.
switchport access vlan 50
switchport mode access
srr-queue bandwidth limit 10
switchport access vlan 120
switchport mode access
srr-queue bandwidth limit 20
So port 13 is limited to 10% of the bandwidth and port 12 is limited to 30%
The issue I'm having is that if these two 'WAN Connections' were to transfer files between each other you would think that the speed would be of the slowest link, but that is not the case. If a computer on port 13 downloads from 12 it gets up to about 340KB, which is way more that port 12 should be able to handle
If computer on port 12 downloads from 13 then the max speed it gets is about 64KB, which is what i expect.
So is there a way to get this to act in a asymmetrical way and not a symmetrical way which it seems to be doing at the moment? i.e. if port 13 downloads from port 12 then speeds shouldn't go above 10% of the link....
So port 13 is limited to 10% of the bandwidth and port 12 is limited to 30%"
Actually, you've defined port 13 limited to 20% (egress) and port 12 limited to 10% (egress). Also these values are not always exact.
If you configure this command to 80 percent, the port is idle 20 percent of the time. The line rate drops to 80 percent of the connected speed. These values are not exact because the hardware adjusts the line rate in increments of six. "
