Avaya AP-4, AP-6, AP-5 manual TCP/UDP Port

Filtering

The AP can filter these protocols in the wireless-to-Ethernet direction, the Ethernet-to-wireless direction, or in both directions. Click Edit and use the Status field to Enable or Disable the filter.

TCP/UDP Port

Port-based filtering enables you to control wireless user access to network services by selectively blocking TCP/UDP protocols through the AP. A user specifies a Protocol Name, Port Number, Port Type (TCP, UDP, or TCP/UDP), and filtering interfaces (Wireless only, Ethernet only, all interfaces, or no interfaces) in order to block access to services, such as Telnet and FTP, and traffic, such as NETBIOS and HTTP.

For example, an AP 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.

Protocol	Destination	Protocol	Interface	Status
Type	Port	Name		(Enable/Disable)
(TCP/UDP)	Number
UDP	137	NETBIOS	Ethernet	Enable
		Name
		Service
