Maximum SPAN sessions on different switches

ivanchello

For my task, I need to buy a switch that supports at least two SPAN sessions. I'm looking at SF350/SF352 or catalyst 2960cpd-8tt-l. However, the datasheets of these models do not contain information about the maximum number of sessions. Before I buy something, I need to be sure about it. Help me please.

And if these models support only one session, please tell me a switch with a small number of ports that allows you to configure at least 2 SPAN sessions.

Most the information related to SPAN will be in the configuration guide and any Limitration depends on IOS code running you can look configuration guide example for 2960 : (Traffic monitoring in a SPAN session has these restrictions:)

How to Ask The Cisco Community for Help

Thank you very much for the articles, I have already read them.

Now I have another question. The number of sessions within the same series may differ? Does an 8 port 2960 series switch have exactly the same number of sessions as SPAN on a 24 port 2960 series?

In the second article, you gave examples where the CBS250 / 350 is configured, but I need to configure the SF350. Or will they have the same setup?

Thank you!
