For example, M at E1/0/1 of SwitchA, then the configuration procedures are as follows:
Switch A, Switch B, Switch C:
SwitchA (Config)#mac-vlan mac 00-03 -0f-11-22-33 vlan 100 priority 0
SwitchA (Config)#interface ethernet 1/0/1
SwitchA (Config-Ethernet1/0/1)# swportport mode hybrid
SwitchA (Config-Ethernet1/0/1)# swportport hybrid allowed vlan 100 untagged
SwitchB (Config)#mac-vlan mac 00-30-4f-11-22-33 vlan 100 priority 0
SwitchB (Config)#exit
SwitchB#
SwitchC (Config)#mac-vlan mac 00-30-4f-11-22-33 vlan 100 priority 0
SwitchC (Config)#exit
SwitchC#
15.5.4 Dynamic VLAN Troubleshooting
On the switch configured with dynamic VLAN, if the two connected equipment (e.g. PC) are both
belongs to the same dynamic VLAN, first communication between the two equipments may not go
through. The solution will be letting the two equipments positively send data packet to the switch (such
as ping), to let the switch learn their source MAC, then the two equipments will be able to communicate
freely within the dynamic VLAN.

Priority of dynamic vlan and vlan ingress filtering for processing packets is: dynamic vlan> vlan ingress
