address. (See the description for SubMask on page 3-99.)
• Service Type – Packet priority settings based on the following criteria:
- Precedence – IP precedence level. (Range: 0-7)
- TOS – Type of Service level. (Range: 0-15)
- DSCP – DSCP priority level. (Range: 0-64)
• Protocol – Specifies the protocol type to match as TCP, UDP or
Others, where others indicates a specific protocol number (0-255).
(Options: TCP, UDP, Others; Default: TCP)
• Src/Dst Port – Source/destination port number for the specified

• Control Code – Decimal number (representing a bit string) that
specifies flag bits in byte 14 of the TCP header. (Range: 0-63)
• Control Code Bit Mask – Decimal number representing the code bits
to match.
The control bitmask is a decimal number (for an equivalent binary
bit mask) that is applied to the control code. Enter a decimal
number, where the equivalent binary bit “1” means to match a bit
and “0” means to ignore a bit.
The following bits may be specified:
- 1 (fin) – Finish
- 2 (syn) – Synchronize
