Switch 3560G

I would like to know if the switch 3560G-24PS has a non-blocking architecture .

Cisco Catalyst 3560G-24PS: 24 Ethernet 10/100/1000 ports with PoE and 4 SFP-based Gigabit Ethernet ports; 1RU

so if full utilized, the back plane must be at least (24+4)x2 = 56 gbps

in datasheet it is said to have 32 Gbps forwarding bandwidth.

i am afraid it is not non-blocking.

can any one confirm it? or correct me if i am wrong.

Well, it's an adjunct to what you just indicated about.

>so if full utilized, the back plane must be at least (24+4)x2 = 56 gbps

and PPS must be at least (1488000x28)=41.7 Mpps

in datasheet it's said to have 38.7Mpps forwarding rate.

I mean, Cat3560G-24PS is NOT non-blocking and wire speed, you're right.

In other word, it's non-blocking up to 26port, by the way.
