swL3IpCtrlIpDirectedBroadcastState
Module: DGS-3420-28PC-L3MGMT-MIB
OID (symbolic): DGS-3420-28PC-L3MGMT-MIB::swL3IpCtrlIpDirectedBroadcastState
OID (numeric): 1.3.6.1.4.1.171.11.119.3.3.2.1.3.1.21

What is swL3IpCtrlIpDirectedBroadcastState?
Controls whether IP directed broadcasts (packets addressed to the interface's subnet broadcast address) are forwarded onto the local segment. Admins typically disable this to prevent the interface being used in broadcast-amplification (smurf-style) attacks.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.11.119.3.3.2.1.3.1.21 snmpwalk -v2c -c public <target> DGS-3420-28PC-L3MGMT-MIB::swL3IpCtrlIpDirectedBroadcastState
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.11.119.3.3.2.1.3.1.21.1 snmpget -v2c -c public <target> DGS-3420-28PC-L3MGMT-MIB::swL3IpCtrlIpDirectedBroadcastState.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.11.119.3.3.2.1.3.1.21.1 i <value>
