GLC-T works only in 1000 speed when in 67xx-SFP cards (hardware limitation?).
We use 6748-GE-TX for 10/100/1000BaseT in our 6500s/7600s, so we have the same issue as you. Does anyone know what happens with the ES/SPA cards? -- Tassos Saku Ytti wrote on 25/9/2008 1:34 μμ:
http://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_6981.html Is this accurate? Can someone find errors? I seem to recall cuSFP works in 10/100/1000 speeds in SUP720-3BXL supervisor ports (well other is dual personality anyhow) Mostly, I'm highly disappointed if there aren't any GE SFP ports at all in 7600/6500/4900/4500 that'll do 10/100 speeds. This mean, if you currently have 3750-12S and you're looking to step up, you need to buy three linecards, 1GE SFP, 100M SFP and 10/100/1000 cu, increasing costs in unacceptable way. Anyone know what's the state in foundry, huawei and extreme?
