Function Name:
IP TCP/UDP Port Classification Function Description:
The GSM Series switches allow the administrator to configure QoS rules based on Layer 4 networking protocols such as HTTP, FTP etc. The switch provides built in rules to down prioritise, or prioritise different types of services.

Therefore if the switch is congested and port 1 is sending port 80 requests and port 2 is requesting other services such as IP Telephony (VoIP) some packets from port 1 may be dropped because of the lower priority.
