• Src/Dst Subnet Mask – Subnet mask for source or destination
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

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:
