 If 802.1x port-based access control is disabled, all the ingress
EAPOL packets are discarded.
B - Forwards the ingress spanning tree BPDU and 802.1x EAPOL packets
across all the VLANs and the ports. The switch or stack behaves as
follows:
 If STP, RSTP, and MSTP are disabled, the ingress BPDUs are
flooded on all the ports.
 If STP, RSTP, MSTP, and 802.1x are disabled, the BPDU and
EAPOL packets are flooded on all the ports.
 If STP or RSTP is enabled and 802.1x is disabled, the EAPOL
packets are flooded on all the ports, except for ports in the blocking
state.
 If MSTP is enabled and 802.1x is disabled, the EAPOL packets are
flooded on all the ports, including ports in the blocking state.
C - Forwards the ingress BPDU and EAPOL packets only on untagged
ports of the VLAN where the ingress port is a member. Packets are not
forwarded from tagged ports. The VLAN is identified by the PVID assigned
to the ingress port.
D - Forwards ingress BPDU and EAP packets from both tagged and
untagged ports of the VLAN where the ingress port is a member. The
VLAN is identified by the PVID assigned to the ingress port.
Example
This command sets the switch or stack mode to A to discard all ingress
BPDUs and 802.1 EAPOL packets:
set switch multicastmode=a
