Mapping IP Port Priority

You can also map network applications to Class of Service values based on
the IP port number (i.e., TCP/UDP port number) in the frame header.
Some of the more common TCP service ports include: HTTP: 80,
FTP: 21, Telnet: 23 and POP3: 110.
Command Attributes
• IP Port Priority Status – Enables or disables the IP port priority.
• IP Port Priority Table – Shows the IP port to CoS map.
• IP Port Number (TCP/UDP) – Set a new IP port number.
• Class of Service Value – Sets a CoS value for a new IP port. Note that
"0" represents low priority and "7" represent high priority.
Note: IP Port Priority settings apply to all interfaces.
