The QFE is not a good choice on the Ultra 1 ... you need a ton of CPU to run a
QFE properly ...

thus ... info doc 17416

Why is there a limit on cards supported on EX000 platforms?
 A:  Ideally we would like to support four to six, and we are trying to get
      there.  Both the Sunfire/Starfire groups and NPG have agreed to two
cards
      maximum as of today, but are working together to find ways to increase
      the performance and the number of cards supported.

  Q:  Why only 1 card in Ultra 2?
  A:  CPU limitation.  Can't get 500Mhz per card for more than one card.

  Q:  Did you say 500 Mhz per card?
  A:  Yes.  This can be in any configuration.  You can have two 250 MHz CPU's,
      three 167's, five 110's, etc.  How you get 500 Mhz is up to you and your
      customer.

  Q:  What do you mean "at least a 167 Mhz CPU for trunking"?
  A:  For trunking, all the interrupts that occur are managed by one CPU.
With
      such a heavy load on one CPU, you need to have at least a 167 CPU to
handle
      this.  You cannot choose 110 CPU's or 75 CPU's.

or better yet ...

Hardware requirements

 One CPU per Quad FastEthernet port is recommended for maximum throughput

 For systems running at 200 MHz or greater, a minimum of two CPUs per Quad
FastEthernet
 adapter card is recommended
