3750 stacking question

francisco_1 · ‎07-07-2008

by stacking 9 switches which is the limit, should i expect to get the full 32Gbps Backplane bandwidth?

How does it work on the 3750 stacking?

without the stack, what is the backplane bandwidth on each 3750?

does cisco have other stackable switches?

In addition to Andrew's reference.

"by stacking 9 switches which is the limit, should i expect to get the full 32Gbps Backplane bandwidth?"

I believe the stack behaves more like a daisy chain then a backplane. Think of dual 8 gig inter-member links for Stackwise and dual 16 gig for Stackwise+.

According to Table 2 in "http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps5023/product_data_sheet0900aecd80371991.html", 32 Gbps fabric. (NB: the 3750 forwarding rates, for 48 port models, looks insufficient for wire rate.)

The 3750-E series.

6500 VSS is similar to stacking.
