22 GX1026i Smart Ethernet Switch
TCP/UDP Port based
This page provides Class of Service based on TCP/DUP protocol. In addition to the
well known protocols, this switch supports protocol range to cover a wide range of
protocols. The mask number is used to define the protocol range. The result of the
calculation is a range of acceptable protocol number.
Example:
The protocol should range from 1~65535 and the mask should be between
1~255. if you fill 7549 in the protocol field and fill 13 in the mask field, you will
get the actual protocol numbers which can pass the switch. The calculation
procedure is listed below:
• Transform the mask number into the binary form 1+4+8=13
• Subtract 0, 1, 4, 8, 13 from 549, you will get result of 549, 548, 545,
541, 536
• The protocol number listed above can pass the switch. Selecting “Override”
makes this page configuration override the port based, 802.1p based and IP/
DS based configuration. Click Update to save the settings.
