[c-nsp] 7200 port adapters

[Fredrik.Jacobsson at enskilda.se]

I did searches on both Google and Cisco.
Read the relevant information. Including that document.

But I couldnt match that it uses 200 points and the warning from show ver:
"PA's (PA-2FE =  400) has/have over subscribed 200 bandwidth points in
single port configuration on PCI bus mb2."

Perhaps you could explain how I was supposed to see that? 
I'm not oversubscribing, and yet it tells me that I am.

Other than knowing that the show version shows the maximum theoretical, not
what it uses.
But that was not in the documents.

Thanks
/Fredrik

Hi,

  Even faster would be to search google for the relevant part of the error 
message:
"Cisco 7200 Series Port Adaptor Hardware Configuration Guidelines"
  (with the quotation marks)

  First answer from the search is
<http://www.cisco.com/en/US/products/hw/modules/ps2033/products_configuratio
n_guide_chapter09186a008014cf5c.html>

  In table 1-6 you'll find an entry for
"1 port use of 2-port Fast Ethernet (TX)" (without the quotation marks)
  that confirms 1 port use is only 200BW points

  Please take this as constructive criticism
(Gert - what happened to your usual "teach a man to fish" ?)
