GR2K-GA-0014 1-51
Ver. 07-02
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_tos <DSCP_Value>:0-63(decimal)
This parameter enables the filtering function that sets four-layer information
(TCP, UPD, or ICMPv6) to the packet with an extended header as conditions
using RP-C6, RP-D6, RP-CV, RP-DV, GR2000-1B, GR2000-2B, GR2000-2B+ or
GR2000-BH.
The protocol parameter that can be jointly used with this parameter is only ip.
The operating parameter that can be jointly used with this parameter is only
forward and drop.
Input Examples
1. Setting the filter flow information:
Designation of relay and/or discard(IPv6 filter)
Designate relaying the IPv6 packets with the transmitter IPv6 address being
3ffe:501:811:ff01:1::1, the high-order protocol being TCP and the destination port
number being 23 (telnet). Designate other packets to be discarded.
Designation of policy routing:
Output packets with transmitter IPv6 addresses being 3ffe:501:811:ff01:1::1
from the interface with the interface name of Osaka making the next hop address
3ffe:501:811:ff20:1::1.
