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

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
