Hi, which is the throughput of the 3560 in layer three?
Thanks

Hi Heiber,
Throughput is the highest rate at which packets can be sent without packet loss. Measures capacity of forwarding engine(s).
it doesnt calculate with layer 3. Please see the below throughput detail for 3560 series switches,
In some other switches you can calculate it from the Linecards and Switch Fabric bandwidth as well.
Please refer the below doc which explains more about the 3560 switch capacity,
Regards,
Aru

To add a little to Arumugam's post . . .
Fabric bandwidths are often quoted duplex, so for example, a 3560's 32 Gbps fabric would support up to 16 gig duplex ports w/o oversubscription; more port bandwidth may need more fabric bandwidth.
Wire-rate Ethernet, for 64 byte size packets requires 1.488 Mpps per gig, so 38.7 Mpps supports 26 Gbps (non-duplex) or about 13 gig duplex ports. (NB: larger packets require a lower PPS, i.e. often same hardware's throughput increases with increased packet size.)
PS:
The later E and X series 3560s usually offer wire-rate perfomance for all ports.
PPS:
Oh, and a 3560's L3 perforamance is often the same as it's L2 performance (if a packet's L3 done all by "hardware").
