[c-nsp] PA-FE-TX, PA-FE-TX/ISL, PA-2FE-TX, PA-2FE-TX/ISL

[Sridhar Ayengar]

I've read in the list archive of people complaining about the 
performance of the /ISL port adapters.  I've been using a number 
PA-FE-TX/ISL for years without trouble.  However, now I need to upgrade 
to PA-2FE port adapters to get auto-duplex negotiation.

I understand from my readings that the PA-2FE-TX/ISL can't push both 
ports at line rate.  However, I'll be using only one port of the two. 
Is there any downside to using the PA-2FE-TX/ISL if I'm only using one 
port, and I'm not using ISL (or any other VLAN stuff for that matter) at 
all?

Peace...  Sridhar
