Rate-Suppression - Planet SGS-6341 Series Command Manual

Parameters:
interrupt: the interrupt mode; poll: the poll mode.
Command mode:
Global Mode.
Default:
Poll mode.
Usage Guide:
There are two modes that can respond up/down event of the port. The interrupt mode means that interrupt hardware
to announce the up/down change, the poll mode means that software poll can obtain the port event, the first mode is
rapid. If using poll mode, the convergence time of MRPP is several hundred milliseconds, if using interrupt mode, the
convergence time is less than 50 milliseconds.
Notice: The scan mode of the port usually configured as poll mode, the interrupt mode is only used to the
environment of the good performance, but the security of the poll mode is better.
Example:
Configure the scan mode of the port as interrupt mode.
Switch(config)# port-scan-mode interrupt

4.1.12 rate-suppression

Command:
rate-suppression {dlf | broadcast | multicast} <packets>
no rate-suppression {dlf | broadcast | multicast}
Function:
Sets the traffic limit for broadcasts, multicasts and unknown destination unicasts on all ports in the switch; the no
command disables this traffic throttle function on all ports in the switch, i.e., enables broadcasts, multicasts and
unknown destination unicasts to pass through the switch at line speed.
Parameters:
use dlf to limit unicast traffic for unknown destination; multicast to limit multicast traffic; broadcast to limit broadcast
traffic. <packets> is the limit of packet number, ranging from 1 to 1488905. For non-10GB ports, the unit of <packets>
is PPS, that is, the value of <packets> is the number of packets allowed to pass per second; for 10GB ports, the unit
is KPPS, that is, the value of <packets> multiplies 1000 makes the number of packets allowed, so the value should
be less than 14880.
Command mode:
Port Mode.
Default:
No limit is set by default. So, broadcasts, multicasts and unknown destination unicasts are allowed to pass at line
speed.
