All,


What is the routing performance of WS-C3560-8PC-S? Can I get 100Mbps out of the interface?

Correct Answer by Edison Ortiz about 8 years 3 months ago

You are right, but you can take the information provided on this page:


http://www.cisco.com/en/US/products/hw/switches/ps5528/prod_models_comparison.html


and come up with the numbers from the previous page.


Based on the page above, the 8port switch produces 2.7 Mpps which based on my calculations taken from the 2 models listed in the initial link rates about 3.6Gbps..

Mohamad,


That's incorrect !


The link you've posted is related to the Advanced IP Services feature set, not the hardware itself.

I have read that before. It did not mention any performance about routing. I am wondering if routing can have the same performance as swtiching.

See the column L2/L3 ? 3560 indicates L3 so those stats where measure with routing involved.


HTH,

There is nothing about C3560-8PC, the 8 porter I am looking for.

Depending on which specs you examine, you might be able to obtain full wire rate from all ports (for either L2/L3). If true, answer to your question is yes. If not true, very likely switch's L3 performance is (much) more than 100 Mbps.


PS:

Where the specs conflict:


Table 2 in http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps5528/product_data_sheet09186a00801f3d7d.html shows, for performance, 32 Gbps forwarding bandwidth (all 3560s?) and 2.7 Mpps (Cisco Catalyst 3560-8PC), but in Edison's first reference, although the 8 port 3560 isn't listed, other 10/100 3560s are noted with less than 32 Gbps.


The Mpps rating, 2.7 Mpp, is what's needed for wire speed, only whether 3.6 Gbps fabric bandwidth is provided is unclear.
