How does Source port filtering work?
When you create a source-port filter, the switch automatically sets the filter to forward traffic from the designated source to all destinations for which you do not specifically configure a “drop” action. Thus, it is not necessary to configure a source-port filter for traffic you want the switch to forward unless the filter was previously configured to drop the desired traffic. Details about configuration of the filter command can be reviewed in the Access Security Guide for the 5400zl, 3500yl, and 6200yl products.
