From the diagrams in the Installation and Configuration docs for each PA, it seems the PA-2FE-TX has PA-2FE-TX on the faceplate and the PA-2FEISL-TX has Fast Ethernet/ISL on the faceplate.

It seems that PA-2FE-TX/ISL == PA-2FEISL-TX. There is no difference. I have to look specifically for a PA-2FE-TX. Damn. Peace...

The NPE-G2 is better if you want to forward some 1Gbps through the box (configuration-dependent). Bottom line, the NPE-G1/G2 gives you great value with those on-board Gig-E ports. Still not great if you want to handle a line rate DDoS attack with minimum size packets...

If you are shopping the used market, you may be better off with the 7200 series. The 7500 isnt worth the juice it sucks and even when it was supported, it was an abysmal experience. I'd agree with you on the 7200 preference, and the horrible power usage, but there *were* good times with the 7500. 11.1CC and a bunch of FDDI rings was one of the most trouble-free network setups I've worked with, as long as no-one tried to change cards and tickle the joys of Online Insertion and Reboot.

Still not great if you want to handle a line rate DDoS attack with minimum size packets... Agree - but if the budget is tight, some pain might not be avoidable. My take is if you want to handle 1Gbps (or better) on a sustained basis (as opposed to a couple of hundred-Mbps at peak), you really should be looking beyond the 7200. Absolutely agreed.

Re: [c-nsp] PA-FE-TX, PA-FE-TX/ISL, PA-2FE-TX, PA-2FE-TX/ISL
I would stay far far away from the 2 port FE port adapters, no matter what they say on them. I would stick with VIP2-50 (or higher) with 128DRAM and only port adapters that work well in there. Only VIP2-50 (or better) and RSP in the chassis. Nothing else. Use a cheap catalyst switch like the 2950 or 3524XL and port-channels. The router is cabled only to the switch. Everything is cabled only to the switch. Use vlans for fanout. This should be relatively stable for the rsp platform and give you the best throughput and flexibility. Also it is dirt cheap. If you are shopping the used market, you may be better off with the 7200 series. The 7500 isnt worth the juice it sucks and even when it was supported, it was an abysmal experience.
