Re: How many Span destination port can i have ???

You can have multiple span sessions with different src/dst ports. It's going to depend on the platform and other features you have configured on the port. Is there a specific platform of interest?

Hi,

it depends on platform and CatOS/IOS.

See the "Feature Summary and Limitations" sections in following article:

Don't forget there's a performance penalty associated with Span. The more you monitor the higher the penalty.

Again, it depends on the platform.

See the Performance Impact part of the document I mentioned before.

There is no performance impact on Catalyst 5000/6000 family, e.g.
