Filtering/QoS Information
GR2K-GA-0014 1-35
Ver. 07-02
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).
The policy group name designated 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)
This parameter enables the function that rewrites a DSCP value. It rewrites the
DSCPvaluethatistheuppersixbitsofaTOSfield.ThelowertwobitsofaTOS
field are not rewritten. On the output side, do not specify this parameter to
multicastpackets.Itcannotbesetinthetunnelinterface.
Default: -forward
Range of value: -replace_dscp <DSCP_Value>: 0 to 63 (decimal).
Designate 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.
