To minimize network outages, you can predownload an image to the access point from the controller without resetting the access point or losing network connectivity.
This process is very slow and can require several time. After the access point discovers the controller with the new image, the AP downloads the new image, resets, goes into discovery mode, and rejoins the controller. See įor more information on how to use XMODEM to do this.Normally, you need to upload the image to the controller and reset it to upgrade WLC/Aps this causes the access point to go into discovery mode.
This is what you need to do if for some reason the switch looses its IOS. bin file from the tar archive and then use the XMODEM protocol and a terminal program such as hyperterm upload the image back onto the switch using the console cable. This assumes that the switch has a working IOS on it already.Ģ) Extract IOS.
To restore the IOS archive file to the switch you can:ġ) get do the basic network configuration, telnet into the switch and use the following command: To restore the configuration you can either:ġ) use DHCP and TFTP as described in AutoInstall Using DHCP for LAN Interfaces ( ) orĢ)you can get the basic networking up on the switch using the console and then telnet into the switch and use the following commands: This will create a tar archive called switch1-ios.tar of the IOS and web device manager files from your switch on your tftp server. To backup the IOS and the switches web-based device manager (the web interface files) you need to do the following: To backup the configuration of a Catalyst 2950 switch you telnet into the switch and run the following command:
