Filtering/QoS Information

[-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.

		High-order 6 bits are designated.

	Default:			-forward

Range of value: -replace_tos <DSCP_Value>:0-63(decimal)

[-sacnThisextension]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.
