Description: If dhcp security check enabled for this vlan virtual interface
What is hh3cDhcpToL3AddressCheck?
This enabled(1)/disabled(2) flag controls whether DHCP security address checking is turned on for the given VLAN virtual interface. When enabled, the switch validates DHCP client traffic on that interface against the DHCP snooping security bindings to block spoofed source addresses. An admin would set this to enabled(1) on a user-facing VLAN interface to prevent IP/MAC address spoofing attacks.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.25506.8.35.8.1.3.1.3 snmpwalk -v2c -c public <target> HH3C-LswDHCP-MIB::hh3cDhcpToL3AddressCheck
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.25506.8.35.8.1.3.1.3.1 snmpget -v2c -c public <target> HH3C-LswDHCP-MIB::hh3cDhcpToL3AddressCheck.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.25506.8.35.8.1.3.1.3.1 i <value>
