dDhcpSnpVerifyMacAddressEnabled
Module: DLINKSW-DHCP-SNOOPING-MIB
OID (symbolic): DLINKSW-DHCP-SNOOPING-MIB::dDhcpSnpVerifyMacAddressEnabled
OID (numeric): 1.3.6.1.4.1.171.26.131.1.1.2
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: This object indicates whether the DHCP snooping validates the source MAC address matches the client hardware address in the received DHCP request packet.
What is dDhcpSnpVerifyMacAddressEnabled?
When enabled (the default), DHCP snooping checks that the source MAC address in a DHCP request frame matches the client hardware address field inside the DHCP payload, rejecting requests that don't match as a basic spoofing check.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.26.131.1.1.2 snmpwalk -v2c -c public <target> DLINKSW-DHCP-SNOOPING-MIB::dDhcpSnpVerifyMacAddressEnabled
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.26.131.1.1.2.1 snmpget -v2c -c public <target> DLINKSW-DHCP-SNOOPING-MIB::dDhcpSnpVerifyMacAddressEnabled.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.26.131.1.1.2.1 s <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> dDhcpSnpVerifyMacAddressEnabled.1
