Description: Specifies whether non-SNAP-encoded IEEE 802.3 packets should be filtered on this VLAN. This filter is applicable to 10BT, 100BT, and OC3 cards. It filters traffic in both upstream and downstream directions. Default is false. This filter can also be enabled for a specific ComPort via the MIB attribute hcxStuL2NonSnapFiltEnbl.
What is hcxVlanL2NonSnapFiltEnbl?
This read-write true/false attribute, false by default and applicable to 10BT, 100BT, and OC3 cards, filters non-SNAP-encoded IEEE 802.3 packets in both directions on this VLAN, and can also be enabled per ComPort. An admin uses it to block plain 802.3-framed traffic when the VLAN is meant to carry only other frame types. For example, an admin enables this on a VLAN meant to carry only Ethernet-II traffic, blocking any raw 802.3-framed packets that appear.
