How do you reset to the default config on a 2950-T switch? The config I loaded does not seem to work very well and I would like to try the default config. When I reload the config, will it knock all the clients offline? I'd like to not have to do this after-hours. Thanks

I just did this yesterday! I added the web gui to make things quicker/easier.

add ip http server and make yourself a username and give correct privilege. From there http into the switch and there is an option to reset to factory default. It will require a reboot, so do this after hours.

Here's also a doc from cisco:

I added the ip http server option, but the switch still does not show up on the network. When I ping it, no response. I look at the config and it doesn't have an IP address. I have some 2950G's that I used this same config on with no problem...
Question 1: What do I need to do to get an IP address plugged in and available on the network.
Question 2: After that, I assume that a reset to factory defaults will be an option via the above tip.

Okay..I have to amend my above post. I have 3 2950T - 24 switches, but only 1 is available via ping, telnet or http. I reloaded the configs on all 3 switches and the result is the same: only the 1st switch is "pingable". Even if you are plugged into a different switch, only the 1st is "pingable". Below is the config, please advise. Thanks

Correct, this is the one that responds to ping. The other 2 switches are using the same config with only the IP address and the host name changed. Everything else is the same.

Each 2950 is using a Cat 5e cross-over cable going from Gigabit port 1, Switch 1 to Gigabit port 2, Switch 2. Then Gigabit port 1, Switch 2 to Gigabit port 2, Switch 3.

Make sense?

This is the same as I have my 2950G's using the gigastack modules...
