Thanks all for the replies! A person also responded privately with the opinion that most people want Netflow down the road. Unfortunately, since Netflow has been removed from the 45xx with the Sup6 it would require 65xx at $$++. Squarely in the want vs. need bucket for us Unfortunately, I left out that that most of the gig uplink connections are fiber so a 3560G doesn't have enough SFP ports. I did find the WS-C3750G-12S-E which looks like the good low-cost option. On the minuses side, it's a softswitch, and no 10G uplinks for linking in the server access switches. The main downside here is advocating for their replacement and purchasing strategies around here. eBay, used equip., etc... are pretty much verboten. Basically, if we buy these now, they'll be here in 5 years and forklifting the network core could be painful. Point well taken on the stacking related maintenance downtime issue. We plan on doing pure routing and GLBP so thankfully this wouldn't affect us. This issue will bite us with the server access layer. :( I'll join the many who want this problem to go away. The availability issues with 45xx and 49xx shouldn't be a problem as 4507's are being spec'ed for some access switches and we have until summertime to do this. It's interesting though, makes me wonder if it's just really high demand, or C pushing other platforms. I discovered the 4928-10G, but the 4900M config comes in cheaper, apparently due to only needing one 8 port card. I'm assuming the 2:1 oversubscription is not an issue when running these 10G ports at 1G. Only thing is 2000W of power supply vs. 600W. It does seem silly to do the twingig thing; if only there was a 20-port sfp halfcard!
