The tagged, untagged, Auto, and Forbid options are configured in the VLANcontext. Since dynamic VLANs operate as tagged VLANs, and it is possible that atagged port on one device may not communicate with an untagged port on anotherdevice, GarrettCom Inc. recommends that you use Tagged VLANs for the staticVLANs.A dynamic VLAN continues to exist on a port for as long as the port continues to receiveadvertisements of that VLAN from another device connected to that port or until you:• Convert the VLAN to a static VLAN• Reconfigure the port to Block or Disable• Disable GVRP• Reboot the switchThe time-to-live for dynamic VLANs is 10 seconds. That is, if a port has not received anadvertisement for an existing dynamic VLAN during the last 10 seconds, the port removes itselffrom that dynamic VLAN.Configuring GVRPThe commands used for configuring GVRP are235
