You are correct.  I am using firmware version 6.2.7.2, which is the latest.  I just looked in the Release Notes for this (6.2.7.2) release and it says support for a period in the hostname was added in 6.2.1.6... Release 6.2.1.6  Added support for character ‘.’ (period) in the hostname
Hello, I've been working with these switches and have a question I'd love some input on.  My inventory mgmt automatically polls our network equipment for tracking purposes, and within the switch configs, we are forced to set the hostname using "_" if we wish to delineate a location within the hostname.  Is there any way to be able to use "." rather than the underscores, as the underscore conflicts with our tracking software making things difficult to find. Thanks, Jeff
