NT: That of course depends on the typical utilization of that external
interface
based on any statistics you should have gathered to support the need for a
10 or 100 MB connection.

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...

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.
