information. Designate this parameter's out (Outbound) as the flow control of the
output side. When this parameter is designated, only "-priority" and "-discard"
can be set. The setting range for "-priority" is from one to four. This parameter
cannot be set if the output line is a VLAN line.
Default
Range of value
This parameter enables the function that rewrites a DSCP value and that
determines the output priority and queuing priority using the rewritten DSCP
value. The DSCP value and its corresponding output priority and queuing priority
are specified using a qos-tos-map command. This parameter 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.
DSCP (Differentiated Services Code Point), CU (Current Unused)
Default:
Range of value: - replace_dscp<DSCP_Value>:0-255(decimal) (Note 1, 2)
This parameter enables the function that determines the output priority and
queuing priority using the DSCP value of an input packet. The DSCP value and
its corresponding output priority and queuing priority are specified using a
qos-tos-map command. The upper six bits of a TOS field in a receive packet are
treated as a target. The lower two bits of a TOP field are ignored. -priority,
-discard, and -replace_dscp cannot be set when this parameter is set.
