Our configuration: a GSR12008 with two interfaces, an OC12 ATM to the WAN and a gig ethernet to the campus, serving as a border drain. Does someone have real experience configuring this box with SFCs and CSCs? Is a full switch fabric (3 SFCs) and second CSC required or desirable for the gig ethernet interface to work? Could we expect to support a second gig ethernet interface? So many questions! Thanks, John Haskins jhaskins@commserv.ucsb.edu Communications Services University of California Santa Barbara

required. you must have 3 SFCs.

not at full bw; i believe this exceeds backplane bw.

Perhaps you are thinking of the 75xx? I believe the GSR has a 40 Gbps backplane with something like 5 Gbps per slot. More than enough to support a gig-E card at full line rate in each of the slots on the 12008. Of course, whether the CPU, etc. can actually push that much - well, I dunno. Anyone tried it?

my mistake. it is the TTM GE that can not handle full b/w.
