hcxStuL2NonSnapFiltEnbl

Module: COM21-HCXSTU-MIB

OID (symbolic): COM21-HCXSTU-MIB::hcxStuL2NonSnapFiltEnbl

OID (numeric): 1.3.6.1.4.1.1141.2.53.1.1.11

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Specifies whether non-SNAP-encoded IEEE 802.3 packets should be filtered for this ComPort. 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 an entire VLAN via the MIB attribute hcxVlanL2NonSnapFiltEnbl.

What is hcxStuL2NonSnapFiltEnbl?

This read-write true/false object filters non-SNAP-encoded IEEE 802.3 packets for this ComPort in both directions, applicable to 10BT, 100BT, and OC3 cards, defaulting to false, per the description, and can also be set per-VLAN. An admin enables this to block legacy raw 802.3 framed traffic on a specific device's connection, complementing the SNAP filter for the opposite encapsulation type. For example, an admin enables hcxStuL2NonSnapFiltEnbl alongside the SNAP filter to fully block a customer's legacy 802.3 gear from generating unrecognized frame types.
