FIGURE 132 – GVRP options
As the above table indicates a port that has a tagged or untagged static VLAN has the option to
both generate advertisements and dynamically join other VLANs.
The unknown VLAN parameters are configured on a per interface basis using the
CLI. The tagged, untagged, Auto, and Forbid options are configured in the VLAN
context. Since dynamic VLANs operate as tagged VLANs, and it is possible that a
tagged port on one device may not communicate with an untagged port on another
device, GarrettCom Inc. recommends that you use Tagged VLANs for the static
VLANs.
A dynamic VLAN continues to exist on a port for as long as the port continues to receive
advertisements 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 switch
The time-to-live for dynamic VLANs is 10 seconds. That is, if a port has not received an
advertisement for an existing dynamic VLAN during the last 10 seconds, the port removes itself
from that dynamic VLAN.
