If you have configured any user-defined protocols then click OK and then COMMIT.
For example, a device with the following configuration would discard frames received on its Ethernet interface with a UDP
destination port number of 137, effectively blocking NETBIOS Name Service packets. Please note that even the Filtering
Control should be enabled to apply the filter.
5.10.4.2 Adding User-defined TCP/UDP Port Filter Entries
To add user-defined TCP/UDP port filter entries to the table, click Add in the TCP / UDP Port Filter screen. The TCP/UDP

You can add a maximum of 64 TCP/UDP Port Filter entries to the table, out of which 7 are default entries.
5.10.5 Storm Threshold Filter
The Storm Threshold Filter restricts the excessive inbound multicast or broadcast traffic on layer two interfaces. This protects
against broadcast storms resulting from spanning tree misconfiguration. A broadcast or multicast filtering mechanism needs
to be enabled so that a large percentage of the wireless link remains available to the connected mobile terminals.
Entry Status Set the entry status as either Enable, Disable or Delete.

Enable: Filter is applied and filters the packet based on the Port number and port
type.

Disable: No filter is applied.

Delete: Allows to delete only user-defined TCP/UDP port filter entry. When you
attempt to delete default entries, the device throws an error.
