Source/Destination Port Bit Mask – Decimal number representing
◆
the port bits to match. (Range: 0-65535)
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)
Service Type – Packet priority settings based on the following criteria:
◆
ToS – Type of Service level. (Range: 0-15)
■
Precedence – IP precedence level. (Range: 0-7)
■
DSCP – DSCP priority level. (Range: 0-63)
■
◆ 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. (Range: 0-63)
The control bit mask 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
■
4 (rst) – Reset
■
8 (psh) – Push
■
16 (ack) – Acknowledgement
■
32 (urg) – Urgent pointer
■
For example, use the code value and mask below to catch packets with
the following flags set:
SYN flag valid, use control-code 2, control bit mask 2
■
Both SYN and ACK valid, use control-code 18, control bit mask 18
■
SYN valid and ACK invalid, use control-code 2, control bit mask 18
■
Time Range – Name of a time range.
