Consider, The switch as a pc for a while, where the total ports bandwidth capacity is the size of your pc's hard drive, and the switch back plane is the Ram installed in your pc, Should this two capacities be equal ?, For any data transfer to occur between any devices example Hardisk to Hardisk or CD to Hardisk, the data is first copied to Ram and then written to the disk, thus the bigger the RAM the faster the process of copying will be. Same example can be applied in the case of the Switch ports and the Back plane engine, the more the back plane capacity the faster the data transfer, thus it is no question of over utilization. Hope it helps. -----Original Message----- From: Gayathri [mailto:[EMAIL PROTECTED]] Sent: Fri, March 09, 2001 11:19 AM To: [EMAIL PROTECTED] Subject: switch capacity - backplane The catalyst 6000 series supports upto 130 Gb ports. And the backplane capacity is 32 gbps. So if i use all the 130 gigabit ports , does it mean that i am overutilizing. I cant relate the sizing of the ports to the switch backplane capacity. Thanks in advance for any clarifications recvd.
