NT: Well I was able to test this new feature out on my 45xx model the other day and yes it worked just as expected(pretty cool). The only problem I had was that it only supports 802.1q and on the Cat5 the only blades that support 802.1q are the more expensive (WS-X5224R and a few others.) Most of the blades that folks purchase for their home labs come with the WS-X5213/5213A which only support ISL. I also did a check on CCO for your model and it would seem that this feature is only supported on the Enterprise set of the IOS. You're running the IP only IOS version. Here's a link to the features of 12.2 IOS features by model watch the word wrap... http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122relnt/xpr n122/122feats.htm#xtocid551238 Of course you'll have to lookat the memory requirements to complete the upgrade.. Hint: The upgrade required 32MB DRAM/16 flash.
