Traffic-Priority - H3C S3100 Series Command Manual

drop: Drops the packets.
forward: Forwards the packets.
remark-dscp dscp-value: Resets the DSCP precedence of the packets and forwards them at the
same time. The dscp-value argument is in the range of 0 to 63. You can also enter a keyword listed
in Table 1-15
meter-statistic: Performs the statistics function on traffic policing. It can meter the bytes of the packets
within the limited rate and the bytes of the packets beyond the limited rate. Note that, for the same ACL
rule, the meter statistic keyword in this command and the traffic accounting function are mutually
exclusive in a VLAN.
Description
Use the traffic-limit vlan command to use ACL rules in traffic identifying and traffic policing for the
packet matching with the ACL rules and to set traffic policing parameters and different actions for
packets within the traffic limit and packets beyond the traffic limit on a VLAN.
Use the undo traffic-limit vlan command to disable traffic policing on a VLAN.
By default, traffic policing is disabled on a VLAN.
Only H3C S3100-EI series switches support this command.
Traffic policing configured on a VLAN is only applicable to packets tagged with 802.1Q header.
With broadcast suppression, multicast suppression, or line rate for the inbound direction enabled
on a device, you cannot configure traffic policing on the device. For detailed information about
broadcast suppression and multicast suppression, refer to Basic Port Configuration in this manual.
Related commands: display qos-vlan, reset traffic-limit vlan.
Example
# Perform traffic policing for packets matching ACL 4000 on VLAN 1. Limit the rate within 128 kbps and
drop the packets exceeding the traffic limit on VLAN 1 (assuming that the current device is an S3100-EI
series switch).
