jnxSecAccessVlanDhcpSnoopStatus
Module: JUNIPER-SECURE-ACCESS-PORT-MIB
OID (symbolic): JUNIPER-SECURE-ACCESS-PORT-MIB::jnxSecAccessVlanDhcpSnoopStatus
OID (numeric): 1.3.6.1.4.1.2636.3.40.1.2.1.1.1.1.2
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-only
Description: This object indicates whether Dhcp Snooping is enabled in this VLAN.
If this object is 'true', Dhcp Snooping is enabled in the specified VLAN.
If this object is 'false', Dhcp Snooping is disabled in the specified VLAN.
What is jnxSecAccessVlanDhcpSnoopStatus?
This read-only boolean reports whether DHCP Snooping is enabled on the specified VLAN. An admin checks it to confirm whether the switch is tracking legitimate DHCP client-to-lease bindings on that VLAN, a prerequisite for other protections like Dynamic ARP Inspection and IP Source Guard. For example, an admin troubleshooting why DAI is not blocking spoofed ARP traffic on a VLAN would first check that this object reads 'true' for that VLAN.
