Description: Specifies whether AppleTalk packets should be filtered for this ComPort. This filter is applicable to 100BT and OC3 cards. It is not applicable to 10BT card. 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 hcxVlanL2AppleTalkFiltEnbl.

What is hcxStuL2AppletalkFiltEnbl?

This read-write true/false object filters AppleTalk packets for this ComPort in both directions, applicable to 100BT and OC3 but not 10BT, defaulting to false, per the description, and can also be set per-VLAN. An admin enables this to block legacy AppleTalk chatter from a specific device that shouldn't be generating that protocol on the shared plant. For example, an admin enables hcxStuL2AppletalkFiltEnbl on a ComPort behind an old Mac network still broadcasting AppleTalk discovery traffic.
