Can someone advise me on the steps to upgrade the IOS on a 2900XL (with 8 mb RAM) using a .BIN file (not a .TAR).
OR
Since I'm inspired to try this because I can't get the v11 software on 2900 to create a useable trunk to a 2950. How can I configure a working trunk between these two switches using a native vlan of 11 on the 2950? I'm afraid the CLI commands for the earlier IOS release on the 2900XL don't make much sense to me.

Note: native vlan must match on each side . Also decide which vlan you want the switch management ip to reside in and that vlan must be allowed across the trunks... Also upgrade the 2924 to 12.0 software before doing this . also as far as upgrading the file , get the new version of software , download a free tftpserver for your laptop , give the switch an ip address and give your laptop an address in the same ip address range. Delete the current .bin file in flash , there is only enough room for 1 image and tftp the new file into flash . Change your boot statement to point to this new image and do a copy run start or write mem command. Then do a show boot command and make sure it is pointing at the new image in flash . then reload the switch.

Thanks. It was the upgrade path that I wanted to take, but I'm not sure how to do it using the IOS .bin file. The only instructions I can find on the cisco site involve using a .tar file (which I don't have). See http://www.cisco.com/en/US/docs/switches/lan/catalyst2900xl_3500xl/release12.0_5_wc16/ol256212.html#wp700531

Basically it is just log into the switch do a delete flash:

some times you may need the squeeze command to remove completely the old file and obtain available memory in flash

Thanks everyone. With your assistance I have managed to upgrade my 2900XLs and get them slotted into the rest of the network.
