I wasn't comparing the GSR and the GRF. I was comparing the Cisco 7508
that I used to have at a previous job to the GRF 400 I just got. As far
as the GSR goes, I haven't seen one in real life. It sounds cool, but I
want to see one for myself before I say the thing walks on water. My GRF
works great now, and I'm satisfied with it's performance so far, though
right now it's still not doing much.

Available in two sizes, the GRF 400 holds up to 4 media
cards for up to 4 Gb/s bandwidth, while the GRF 1600
supports up to 16 media cards for up to 16 Gb/s of
bandwidth. The unique GRF switching architecture is
specially designed to handle network growth while
providing consistent, high performance, regardless of the
dynamics of the network.
It has the following cards:
Ascend ATM OC-3c IP Forwarding Media Card
Ascend FDDI IP Forwarding Media Card
Ascend HSSI IP Forwarding Media Card
Ascend IP/SONET OC-3c IP Forwarding Media Card
Ascend 10/100Base-T IP Forwarding Media Card

Now, I've got a GRF 400 with the ATM OC-3c card, the FDDI card, and the
10/100Base-T card. It works flawlessly. And I can't honestly see how the

I've had cisco sales reps claim even more ludicrous things while the
support engineer started turning red, so who knows...
Comparing GateD to IOS becomes more of a religious preference than
anything else. I'm content knowing both, truth be told.
