3 IEEE 802.1X EAPOL
0x1 = Forward this packet type to the Management Controller
0x0 = Filter out this packet type
For the purposes of this filter, a IEEE 802.1X multicast packet is defined to be any
packet that meets all of the following requirements:
• The destination MAC address field is set to the layer 2 multicast address
01:80:c2:00:00:03.
• The EtherType field is set to 0x888E (802.1X PAE).
This field is optional. If unsupported, multicast 802.1X packets will be blocked
when multicast filtering is enabled, unless they are matched by an address filter
configured using the Set MAC Address command. The value shall be set to 0 if
unsupported.
