PLANET WGSW-50040 - Manual (Page 98)

Function:
Configure the scan mode of the port as “interrupt” or “poll”, the no command restores the default
scan mode.
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.
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
3.1.11 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
