I am confused about the maximum bandwidth needed to feed 3538xl switches.
If I have 48 ports running at 100Mbps, the bandwidth needed is 4800Mbps or 4.8Gig. If I am using single mode fiber that can run only 1Gbps, this is not enough. I thought I could run 3,4 or 5 switches using gigabit fiber linked with the gbit link?
A 6500 would be supplying the 3500's.
Thanks for any information on this as it seems to be a grey area.
If u r running 100Mbps on 48ports ,u need 4.8g capacity on the backplane and not on the uplink.Cuz not all the 48 ports would be constantly pumping in 100mbps of data at the same time.1 gig for uplink is sufficient enough for a LAN that is terminating on a L2 switch like 3500 series.And if at all any of the port is pumping in 100mbps of data constantly, then u may consider a gig link to the switch instead of a fast-ethernet connection!Hope it helps.
