Hi,
I have searched high and low and cant seem to find a definitive list that details the backplance capacity of all Cisco's switches
Does anybody have some information if this exists
Thanks

Hi
do find the performance spec available for 2960..
· 32 Gbps switching fabric
· Forwarding bandwidth:
· Catalyst 2960-24TT: 4.4 Gbps
· Catalyst 2960-24TC: 4.4 Gbps
· Catalyst 2960-48TT: 6.8 Gbps
· Catalyst 2960-48TC: 6.8 Gbps
· Catalyst 2960-24TC: 24 Gbps
· Forwarding rate based on 64-byte packets:
· Catalyst 2960-24TT: 6.5 Mpps
· Catalyst 2960-24TC: 6.5 Mpps
· Catalyst 2960-48TT: 10.1 Mpps
· Catalyst 2960-48TC: 10.1 Mpps
· Catalyst 2960G-24TC: 35.7 Mpps
for more info do refer this link..

Generally speaking it's buried in the data sheets. Backplane would imply (to me) a modular chassis - 6000 or 4500 series.
6000 series: 32, 256, or 720 Gbps (depending on supervisor, assuming 6500 series) (http://www.cisco.com/en/US/customer/products/hw/switches/ps708/products_data_sheet09186a00800ff916.html)
4500 series: various, from 28-136 Gbps depending on supervisor and chassis model (http://www.cisco.com/en/US/customer/products/hw/switches/ps4324/products_data_sheet0900aecd801792b1.html)
The discontinued 5500 series has (if I recall correctly) three each 1.2 Gbps data buses on the backplane.
Hope this helps. Please rate helpful posts.

Thanks for that
Now reading my post again i didnt explain myself totally
i am enquiring about the non-chassis based switches like 3550 , 2960 etc... so what i am asking is..
Do these switches operate at wire speed with no contention i.e
2960 24 Port 10/100 can switch at 2.4 Gbps max
Thanks

There is no 2960, but I assume you mean 2950.
Cisco claims these swithes have 13.6 Gbps switching fabric for full wired speed on all ports.
More information can be found at Home > Products & Services > Switches > All Switches

Thanks for the confirmation on wire speed access
13.6 Gbps is fairly generous !!
with regards to the 2960 - think they are new fixed config switches

I guess i will have to dig around the datasheets to find the details
Thanks anyhow

The Cisco Products Quick Reference Guide mentions "wire speed" for several of the non-modular switches (e.g., 4948, 2970, 2955). The same document also cites their respective switching and forwarding capacities.
