GVRP General Operation Note: convert it to a static VLAN or allow it to continue as a dynamic VLAN for as long as needed. You can also use GVRP to dynamically enable port membership in static VLANs configured on a switch. On the switches covered in this guide, GVRP can be enabled only if max vlans is set to no more than 256 VLANs. General Operation When GVRP is enabled on a switch, the VID for any static VLANs configured on the switch is advertised (using BPDUs-Bridge Protocol Data Units) out all ports, regardless of whether a port is up or assigned to any particular VLAN. A GVRP-aware port on another device that receives the advertisements over a link can dynamically join the advertised VLAN. A dynamic VLAN (that is, a VLAN learned through GVRP) is tagged on the port on which it was learned. Also, a GVRP-enabled port can forward an advertisement for a VLAN it learned about from other ports on the same switch (internal source), but the forwarding port will not itself join that VLAN until an advertisement for that VLAN is received through a link from another device (external source) on that specific port 3-4
