Command Manual – QoS/ACL
Quidway S8500 Series Routing Switches
Parameter
inbound: Sets priority for packets received on the port.
ip-group { acl-number | acl-name }: Activates the ACL identified by the acl-number or
acl-name argument. The ACL here can be a basic ACL or an advanced ACL.
acl-number: Sequence number of the ACL, ranging from 2000 to 3999. acl-name:
Name of the ACL, a string beginning with character a-z or A-Z. Note that this argument
cannot contain spaces or quotation marks.
rule rule: Specifies the rule identified by the rule argument of the ACL. The rule
argument ranges from 0 to 127. Without this keyword, this command applies to all rules
of the ACL.
system-index index: Specifies the system index value of the rule. Normally, a applied
rule is assigned a globally unique index value automatically for being indexed. You can
also specify the index value for the rule. In general, you are not recommended to
specify this parameter manually.
auto: Chooses the service parameters allocated automatically by the switch.
remark-policed-service: Reallocates service parameters.
trust-dscp: Reallocates service parameters according to the DSCP values carried by
packets.
dscp dscp-value: Reallocates service parameters according to customized DSCP
values or EXP values. For IP packets, dscp-value is the DSCP priority (six bits in length
in the packet header) ranging from 0 to 63 and is set by users. For MPLS packets, the
dscp-value argument indicates the DSCP priority. In addition, the least three bits of the
value also act as the EXP flag field, which is set simultaneously when the user specifies
the dscp-value argument.
untrusted dscp dscp-value cos cos-value local-precedence local-precedence
drop-priority drop-level: Customizes a set of service parameters. For IP packets,
dscp-value is the DSCP priority (six bits in length in the packet header) ranging from 0
to 63 and is set by users. For MPLS packets, the dscp-value indicates the DSCP
priority value. In additional, the least three bits of the value alao acts as the EXP flag
field, which is set simultaneously when the user specifies the dscp-value argument.
The local-precedence argument is local precedence, in the range of 0 to 7. The
cos-value argument is 802.1p priority, in the range of 0 to 7. The drop-level argument is
drop level, in the range of 0 to 2.
Description
Use the traffic-priority command to activate an ACL for flow classification and choose
a set of service parameters for the matched flow in VLAN (only available to ACL rules
that permit packets).
Use the undo traffic-priority command to remove service parameters for the specified
flow.
