18.6.4 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

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.

application protocols, such as GMRP and GVRP. Therefore, GVRP is a protocol which
