Does anyone have any new info on this, such as if the WS-X6748-SFP is now able to do 10/100/1000 with the GLC-T?
Alternatively, are there non-Cisco RJ45 SFPs which can do 10/100 and can work with the WS-X6748-SFP? While I am here, if you know of a Cisco Gold reseller who would like to provide the Seattle IX with at-cost SMARTnet for a 6509 in exchange for recognition, please privately let me know.
