portInfoIngressFiltering
Module: A3COM0503-PORTINFO
OID (symbolic): A3COM0503-PORTINFO::portInfoIngressFiltering
OID (numeric): 1.3.6.1.4.1.43.10.1.14.1.3.1.8
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: When this is true(1) the device will discard incoming frames for VLANs which do not include this Port in its Member set. When false(2), the port will accept all incoming frames.
This control does not affect VLAN independent BPDU frames, such as GVRP and STP. It does affect VLAN dependent BPDU frames, such as GMRP.
What is portInfoIngressFiltering?
This read-write boolean enables ingress filtering, which discards incoming frames for VLANs that do not include this port. Engineers enable it to enforce VLAN membership rules and prevent unauthorized traffic ingress. When true, only frames for VLANs listing this port as a member are accepted; when false, all frames enter.
