Latency of Catalyst 2960-X

[f.sanzes1]

Greetings,

In my company, we are studying to replace a switch in an office where latency is a very important characteristic.

We are doubting whether to place a Catalyst 2960-X or a Nexus 3000 (since these are the two switches we already have and can place in that office).

Searching through cisco.com I have found the latency of the Nexus 3000 (here: http://www.cisco.com/c/en/us/products/switches/nexus-3000-series-switches/models-comparison.html) but sadly I am not able to find such information about the Catalyst 2960-X.

Does anyone know what the latency of this type of switches is?

Thanks in advance.

Hi

3000 series are specially built low latency data centre switches that can be used in stock exchanges and other high end markets that cannot have any latency  , the 2960 would not come anywhere near it and is not built for that  , its a low end user access switch  , the most you will find regarding what it can do is the pps per second compared to other 2960s

Thank you Mark

Hello again,

Do you know where I can find the forwarding performance table of the Nexus 3000?

Thanks in advance.

Yes check these links , each model can vary so make sure you check the one you have specifically

http://www.cisco.com/c/en/us/products/switches/nexus-3000-series-switches/datasheet-listing.html

Performance

●  5.12 Tbps switching capacity ●  Forwarding rate up to 3.8 bpps ●  Line-rate traffic throughput (both Layer 2 and 3) on all ports ●  Configurable maximum transmission unit (MTU) of up to 9216 bytes (jumbo frames)

[f.sanzes1]

Is that correct?

The slowest 2960X has a forwarding rate of 68.5 Mpps, which is way faster than the 3.8bpps of the Nexus 3000

[Mark Malone]

thats 3.8 billion packets per second , bit quicker id say than 2960 :)

[f.sanzes1]

oh okay yes I understand now, I read bits per second, my bad.

Thank you very much.
