Hi everyone! nice to see such a good resource for out of date switches!
having a weird issue with a 5520, where when certain types of device are plugged in it disables the port. in the JDM as soon as the device is plugged in, the port turns red and is disabled.
so far this has happened with certain WAPs, but it now happening when a cisco meraki switch is plugged into any port. This is happening on multiple switches within the same org (which leads me to believe its a config issue) however the config was not done by myself and I cant seem to find anything in the config that would cause this. I don't believe port security is set on, and auto neg is on.
Im stumped! any experts out there seen this before ?
Cheers !
