We have a client that’s having troubles with download speeds for everything downstream from an A5. At the switch where the A5 is, we get 100/100Mbits. When we go to any of the buildings where there is a C5 the upload will be around 50-80Mbits, but the download speed is always 1.5Mbits. Can anyone think of what might cause this?
All C5s are using the default plan which is set to 1000Mbps for Up and Down. Using SRS for wireless protocol. The interface to the A5 negotiated at 1Gbit and there aren’t any interface errors.
One other item that seems odd in our troubleshooting is that STP frames are not being passed over the A5 link, so each switch on a C5 thinks it’s the root bridge. This issue doesn’t feel related to the speed problem, but it’s one that I’d like to understand and resolve if possible.
Thanks for anyone’s input!
