Configure Port Filters

Port filters can be used to drop traffic based on the source or destination port before forwarding traffic to downstream tools.

config filter deny portsrc <port> alias <filter-alias>

Example:

config filter deny portsrc 514 alias DropSRC514

Create a Destination Port Filter

config filter deny portdst <port> alias <filter-alias>

Example:

config filter deny portdst 514 alias DropDST514

Apply a Port Filter

Assign the filter to the desired monitoring port.

config port-filter <port> <filter-alias>

Example:

config port-filter 3 DropDST514
