Hitachi GR2000 Series manual Specifies the value of high-order 6 bits in the TOS field

Range of value:

Default:

0–255

Forward

Specifies the upper protocol number in decimal. Upper protocols include TCP, UDP, ICMP, and IGMP.

{-forwardDescription:-drop}Specifies the operation when the packet matches the filter condition. The -forwardoption forwards matching packets and the -dropoption discards the matching packets.

Default:

-protocolDescription:<No.>

{<Payload-payloadDescription:Length>}lengthupperSpecifieslimitthe<Payloadupper orLength>lower limit-payloadof the_IPlengthuser datalowerlengthlimit

(value of total packet length minus header in bytes). Table 1-57 shows the relationships between such upper and

lower limits and the resulting user data . In this table, “A” indicates the packet length excluding the header length, and “B” indicates the IP user data length.

Default: None

Range of value: 0–65535.

Table 1-57 Filtering Condition Derived from Relation between Limit Setting Parameter and IP User Data Length

Limit Setting Parameter		Relation between Packet Length	Filtering Condition
		and IP User Data
-	_length_upper_limit	A < or = B	Match
-	_length_upper_limit	A > B	Mismatch
-payload_length_lower_limit		A > or = B	Match
-payload_length_lower_limit		A < B	Mismatch

-tosDescription:<Value>				Specifies the value of high-order 6 bits in the TOS field and
				compares with the high-order 6 bits in the TOS field of receipt
				packet. The low-order 2 bits are ignored.

Precedence				D		T	R	Unused
The six high-order bits are specified.
D = delay		T = throughput			R = reliability

This parameter is used at specifying the high-order 6 bits in the DS field of Diff-serv by the same condition with TOS field.
