On Ethernet 1/0/1, assume that the filter command is configured to filter packets destined
to IP address 2.2.2.2 and the traffic-limit command is configured to limit the rate of
packets sourced from IP address 1.1.1.1 within 128 kbps. Whether packets conforming to
the rate limit of 128 kbps, sourced from IP address 1.1.1.1, and destined to IP address
2.2.2.2 (referred to as packets A later) will be dropped depends on the union-effect
keyword of the traffic-limit command.
z If the union-effect keyword is not specified, the traffic-limit command issues both the
rate limiting action and the permit action. Whether packets A can pass through
depends on the configuration order of the filter command and the traffic-limit
command. If the traffic-limit command is configured after the filter command is
configured, packets A can pass through; otherwise, packets A are dropped.
z If the union-effect keyword is specified, the traffic-limit command issues only the
rate limiting action. Whether packets A can pass through depends on the filter
command. As for this example, packets A are dropped.
egress-port interface-type interface-number: Enables traffic policing for the outbound
packets of the port identified by interface-type interface-number. The interface-type
interface-number argument refers to the port type and port number. If you specify this
keyword-argument combination, this command applies to the outbound unicast packets
that pass the port and match the ACL rules.
z When you configure the traffic policing on a port, an ACL rule can only be applied to
one egress port. If you configure the same ACL rule for different egress ports, only the
last configuration takes effect. To apply the same ACL rule to multiple egress ports,
you need to specify different ACL numbers or rule numbers for the ACL rule.
z If the XRN function is enabled, the egress port can only be a port of the local unit. For
information about XRN, refer to XRN Fabric module of this manual.
z Do not specify the egress-port keyword when configuring traffic policing on ports in an
aggregation group spanning multiple units. Refer to Link Aggregation Operation for
detailed information about link aggregation.
target-rate: Target packet rate (in kbps) to be set. The range of this argument varies with
the port type as follows.
z Fast Ethernet port: 64 to 99,968
z Gigabit Ethernet port: 64 to 1,000,000
