MULTILINK ML2400 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL 11–5
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, GE Multilin
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
