icmpV6DropNeighborSolicitation
Module: CM-SECURITY-MIB
OID (symbolic): CM-SECURITY-MIB::icmpV6DropNeighborSolicitation
OID (numeric): 1.3.6.1.4.1.2544.1.12.10.1.21.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object is used to enable/disable Dropping Neighbor Solicitation.
What is icmpV6DropNeighborSolicitation?
This read-write enabled/disabled INTEGER controls whether the device drops incoming IPv6 Neighbor Solicitation messages. An admin would enable this cautiously since Neighbor Solicitation is part of normal IPv6 address resolution, and dropping it can break IPv6 connectivity on that interface. For example, enabling this on a management interface that shouldn't answer IPv6 neighbor discovery from untrusted segments blocks that reconnaissance vector, at the risk of also breaking legitimate IPv6 neighbor resolution there.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2544.1.12.10.1.21.3 snmpwalk -v2c -c public <target> CM-SECURITY-MIB::icmpV6DropNeighborSolicitation
Get a specific instance (index 1):
