zyVlanIngressCheckState
Module: ZYXEL-VLAN-MIB
OID (symbolic): ZYXEL-VLAN-MIB::zyVlanIngressCheckState
OID (numeric): 1.3.6.1.4.1.890.1.15.3.86.1.2
Node type: OBJECT-TYPE
Type: EnabledStatus
Access: read-write
Description: Enable/Disable tag VLAN Ingress check on the switch. If enabled, the Switch discards incoming frames on a port for VLANs that do not include this port in its member set.
What is zyVlanIngressCheckState?
Setting this object to enabled causes the switch to discard incoming frames on a port if that port isn't a member of the VLAN the frame is tagged for, enforcing strict VLAN membership at ingress. An administrator enables this to prevent VLAN hopping or misdirected traffic from a misconfigured or malicious device sending frames tagged for a VLAN it shouldn't have access to. For example, enabling zyVlanIngressCheckState on an access port would cause the switch to silently drop any frame tagged for a VLAN that port isn't configured to be a member of.
