Filtering/QoS Information

No setting is possible for the IPv4 addresses of 127.0.0.0-127.255.255.255, and IPv4 addresses of class D [224.0.0.0-239.255.255.255) and broadcast address (in which net ID or host ID is a binary number, and all is one or zero).

[-policyThe policygroupgroup<policyname-Groupdesignated-Name>]in the policy-group is designated. When relaying a packet that agrees with the filter condition, the packet is transmitted to the route of the highest priority among the output destinations registered in the policy group designated by this option. Designate in (Inbound) for the list information that has set the policy routing, as the flow control of the reception side.

Default: -forward

Range of value: The policy group name designated in the policy-group information.

Default: -forward

Range of value: -replace_tos <TOS_Value>:0-255(decimal) (Note 1, 2)

[-replaceThis parameterdscp<DSCPenablesValue>]the function that rewrites a DSCP value. It rewrites the DSCP value that is the upper six bits of a TOS field. The lower two bits of a TOS field are not rewritten. On the output side, do not specify this parameter to multicast packets. It cannot be set in the tunnel interface.

Default: -forward

Range of value: -replace_dscp <DSCP_Value>: 0 to 63 (decimal).

[-indexDesignate<No.>]the connection branching index numbers (indexes designated by the DLCI group information or the Vc-Group information). When relaying a packet that agrees with the flow detecting condition, DLCI/VC designated in the group is selected and transmitted. Designate "out" (Outbound) for the list information that has set the connection branching index number, as the flow control of the output side. (This parameter is effective only for RP-A and RP-D.) It cannot be set in the tunnel interface.

Default: -forward

Range of value: 0 to 7.

Note: Define the filtering according to the GR2000 Configuration Settings (universal CLI) manual

*when the IPv4 packets shown in the table below are filtered under the ACK/SYN flag conditions of a TCP header. The filtering of the IPv4 packets shown in the table below that is performed under the ACK/SYN flag conditions of a TCP header is limited when IPv4 packets are used in a way except as described above. The IPv4 packets cannot be properly filtered even if ack and syn parameters are set to the filter flow information.
