I have a Catalyst 4510 that is running IOS version 15.X that has a bug and Cisco recommends upgrading the IOS. Are there additional steps required to perform an IOS upgrade due to licencing Cisco put in place?
Thanks in advance
I agree with Reza. The 4500 file comes in BIN file extension.
So it's as easy as copying the file from your TFTP server/CF to the boot directory, and optionally, configuring the boot variable statement.
