hh3cDhcpSnoop2IfCheckMac
Module: HH3C-DHCP-SNOOP2-MIB
OID (symbolic): HH3C-DHCP-SNOOP2-MIB::hh3cDhcpSnoop2IfCheckMac
OID (numeric): 1.3.6.1.4.1.25506.2.124.2.2.1.2
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: If the value is 'true', MAC address of DHCP packets received on the port will be checked.
What is hh3cDhcpSnoop2IfCheckMac?
When true, DHCP snooping on this port verifies that a packet's chaddr (client hardware address) field matches its Ethernet source MAC, defaulting to false — a common defense against a host spoofing another client's DHCP requests.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.25506.2.124.2.2.1.2 snmpwalk -v2c -c public <target> HH3C-DHCP-SNOOP2-MIB::hh3cDhcpSnoop2IfCheckMac
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.25506.2.124.2.2.1.2.1 snmpget -v2c -c public <target> HH3C-DHCP-SNOOP2-MIB::hh3cDhcpSnoop2IfCheckMac.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.25506.2.124.2.2.1.2.1 s <value>
