zrc

NAME

zrc - Packet rate control

SYNOPSIS

zrc -b -m -d -t -a [-p <port>] [-v <vlan>] [-g <group>] [-M <mac_addr>] [-T <timeout>] [-D <level>] <rate>

DESCRIPTION

zrc sets rate control on Broadcast, Multicast and/or Destination Lookup Failure (DLF) packets. The rate is measured in the number of packets per time period. If the number of packets received of the specified type exceeds the specified rate limit, packets are discarded at the ingress port.

OPTIONS

-b	Enable rate control	for Broadcast packets
-m	Enable rate control	for Multicast packets
-d	Enable rate control	for	DLF packets
-t	Teardown or disable	all	rate control
-a	Display the current	rate control settings

-p <port> Enable rate control on this <port>

-T <timeout> Set time period to <timeout> milliseconds. Default is 1000 (one second).

-D <level> Set debugging output to <level> when running the program.


<rate_limit>		The number of packets per time period above
which	Broadcasts,		Multicasts and/or DLFs will be discarded.
Valid	rate limits		are any number between 0 and 262143.
