What is hcxVlanL2SnapFiltEnbl?
This read-write true/false attribute, false by default and applicable only to 100BT and OC3 cards, filters SNAP-encoded IEEE 802.3 packets in both directions on this VLAN, and can also be enabled per ComPort. An admin enables it to block a specific legacy Layer 2 encapsulation that is unwanted on the VLAN. For example, an admin enables this filter to block legacy SNAP-encapsulated traffic left over from an old protocol no longer used on the network.
