Description: Enable/disable and configure rate-limiting for all traffic
(or for incoming ICMP traffic) on the port(s). By default,
rate-limiting is disabled on all ports. When a port is
configured to rate-limit traffic, it forwards only that
specified amount of traffic (percentage, bits-per-second, or
kilobits-per-second). The remaining over-profile traffic of the
type being rate-limited is then discarded.
Rate-Limiting works on inbound ICMP traffic, or on inbound or
outbound traffic in general. The rate-limit reflects the
permitted forwarding rate of the traffic type. It is visible as
the average rate of the outbound traffic (or outbound ICMP
traffic) originating from the rate-limited port (when in inbound
mode), or as the average rate of the outbound traffic from an
outbound rate-limited port.
Rate-limiting of all traffic is primarily used for end-node
connections (i.e., at the network edge). It is not recommended
for use on links to servers, routers, switches, or the network
backbone or core.
(Rate-limiting all traffic on such links can interfere with
important network functions.)
ICMP rate-limiting is primarily used for throttling worm or virus-
like behavior, and should NOT be used to remove all ICMP traffic
from the network, as this protocol is necessary for routing
functions.
Broadcast rate-limiting is used for inbound broadcast traffic
control to prevent switch from being disrupted by a broadcast
traffic storm if occurred on the port.
Multicast rate-limiting is used for inbound multicast traffic
control to prevent switch from being disrupted by a multicast
traffic storm if occurred on the port.
For more detailed information on rate-limiting, please consult
the product manual.
This is an Interface context command. It can be called directly
from the interface context, or following the
'interface [ethernet] PORT-LIST' command.
Next Available Options:
■
-- Set limits for ICMP traffic only.
■
-- Set limits for all traffic.
■
-- Set limits for broadcast traffic.
