GVRP Operating Notes
■ A dynamic VLAN must be converted to a static VLAN before it can have
an IP address.
■ On the switches covered in this guide, GVRP can be enabled only if max
vlans is set to no more than 256 VLANs.
■ The total number of VLANs on the switch (static and dynamic combined)
cannot exceed the current Maximum VLANs setting. For example, in the
factory default state, the switch supports up to 256 VLANs. Any additional
VLANs advertised to the switch will not be added unless you first increase
the Maximum VLANs setting. In the Menu interface, click on

| 8. VLAN Menu | 1. VLAN Support. In the global config level of the
CLI, use
max-vlans.
■ Converting a dynamic VLAN to a static VLAN and then executing the write
memory command saves the VLAN in the startup-config file and makes it
a permanent part of the switch’s VLAN configuration.
■ Within the same broadcast domain, a dynamic VLAN can pass through a
device that is not GVRP-aware. This is because a hub or a switch that is
not GVRP-ware will flood the GVRP (multicast) advertisement packets
out all ports.
■ GVRP assigns dynamic VLANs as Tagged VLANs. To configure the VLAN
as Untagged, you must first convert it to a static VLAN.
