To be fair to Cisco and maybe I'm way off here. But it seems they do come out with a way to do things first which then become a standard that they have to follow. ISL/DOT1Q HSRP/VRRP etherchannel/LACP Just some examples..... I'm not aware of too many other vendors that create their own protocol, in which they then become a standard?

HP probably was the most helpful vendor i've dealt with in relation to solving/providing inter vendor interoperability solutions. they have PDF booklets on many things we would run into during work. for example, setting up STP between Cisco and HP gear, ( http://cdn.procurve.com/training/Manuals/ProCurve-and-Cisco-STP-Interoperabi... ).
Well, technically, the HP reference tells you how to convert your Cisco default PVST over to MST to match the HP preference.
The handful of HP switches versus the stacks and stacks of production Cisco requiring conversion to suit them was "intimidating" to say the least :-)
To be fair, one is Cisco proprietary while the other is IEEE 802.1Q.
