Settings

Profile name

Specify a unique name to identify the profile.

Protocol

Specify an IP protocol to use to classify traffic by specifying its Internet Assigned Numbers Authority (IANA) protocol number. Protocol numbers are pre-defined for a number of common protocols. If the protocol you require does not appear in the list, select Other and specify the appropriate number manually. You can find IANA-assigned protocol numbers at http://www.iana.org.

Start port/ End port

Optionally specify the first and last port numbers in the range of ports to which this IP QoS profile applies. To specify a single port, specify the same port number for both Start port and End port. Port numbers are pre-defined for a number of common protocols. If the protocol you require does not appear in the list, select Other and specify the appropriate number manually.

To accept traffic on all ports for a specified protocol, set Start port to Other and 0.

Priority

Select the priority level that will be assigned to traffic that meets the criteria specified in this IP QoS profile.

It is strongly recommended that you reserve Very high priority for voice applications.

Connecting serial devices

The Serial to TCP feature enables traffic from a local serial device to be sent over a TCP/IP network. For example, the following scenario shows serial traffic from a point-of-sale terminal being forwarded to a host computer via a wireless link to a TCP/IP network.
