20.6.4 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.

Ping 192.168.1.200

Ping 192.168.1.100
