When I switch the giga port to auto1000 the switch freezes.

When I switch the giga port to auto1000 the switch freezes.

I couldn't get any access, so I reset to the switch defaults.

What is the proper way to change the port bandwidth setting?

- Go to the Web GUI interface.
Configuration > Port Configuration ,
select the port, and click on Modify Selected Port.

Or from CLI,
in configuration level, enter the interface
example:
SWITCH(config)#interface [port number]
SWITCH(config-if)#speed-duplex [select speed/duplex].

Good Luck

You'll lose connection if the port has currently negotiated 100Mbit (i.e. it is connected to a 100Mbit device.

Before changing the speed do a 'show int brief' to see what speed the port is currently running at.

Personally I don't see a real need to force port speeds. Best to leave everything on Auto and let the devices figure out what's best.

Thanks guys,

Matt, I have some servers we rent that need to have their ports limited to 10mps so they don't hog the networks bandwidth.

What do you think is the best way to do this with this switch?

If you have a extra minute a step by step would be great sonce I'm still learning how to use this switch.

Thanks!

My .02

Using auto negotiation is generally fine for deployments using well known equipment brands. There have been cases when mixing different brands of equipment, especially at the edge where NICs are involved where auto negotiation didn't always work consistently.

As a result, most datacenters have policies in place based on administrator preference. My belief is that anything from the core to the closet should be hard set and documented along side the network map. That way, you don't have to rule out port negotiation problems when troubleshooting various link related anomalies. Itâ s more of an insurance policy than anything else.
