a3ComBrgBroadCastLimit
Module: A3COM-BRIDGE-R3-MIB
OID (symbolic): A3COM-BRIDGE-R3-MIB::a3ComBrgBroadCastLimit
OID (numeric): 1.3.6.1.4.1.43.2.9.1.12.1.9
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object specifies the maximum rate, in packets per second, at which broadcast and multicast packets are forwarded through this port. If the number of these packets during a single time interval (specified by a3ComBrgBLimitTimer) exceeds the number allowed during that interval, as calculated from the value of this object, all further broadcast and multicast packets will be discarded for the rest of the time interval.
If this object is set to zero, this feature is disabled for this port.
Note, any changes to this object will only take affect after the system is rebooted.
What is a3ComBrgBroadCastLimit?
This parameter (0 to 100,000 packets per second) caps the rate at which broadcast and multicast frames pass through the port to prevent broadcast storms. Networks engineers tune this to protect sensitive media and reduce unnecessary traffic on congested links. A value of 500 limits the port to forwarding no more than 500 broadcast/multicast packets per second.
