field. This is compared to the upper 3 bits of the ToS field of sent/received
packets. The lower 5 bits of the ToS field are ignored.
Default: None (precedence values are not included in the detecting
condition)
Range of value: 0 - 7 (decimal)
Specifies the upper or lower limit of the IP user data length.
-upper: Upper limit of the IP user data length is designated.
-lower: Lower limit of the IP user data length is designated.
Default: None (TOS values are not included in the flow detecting
condition.)
Range of value: 0 to 65535 (decimal).
Specifies the transmitter port number.
If port to be specified is one: nnnnn
If port number is specified by range:nnnnn-nnnnn
Default: None (the transmitter port number is not included in the flow
detecting condition.)
Range of value: 0 to 65535 (decimal). (Please refer to Table 1-50.)
