CHAPTER 11: VLAN REGISTRATION OVER GARP VLAN REGISTRATION OVER GARP
MULTILINK ML3000 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
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.
Example 11-1: Converting a dynamic VLAN to a static VLAN
ML3000# gvrp
ML3000(gvrp)## show-vlan
=================================================
VLAN ID | NAME | VLAN | STATUS
=================================================
1 | Default VLAN | Static | Active
2 | Blue | Static | Active
10 | dyn10 | Dynamic | Active
ML3000(gvrp)## static vlan=10
ML3000(gvrp)## show-vlan
=================================================
VLAN ID | NAME | VLAN | STATUS
=================================================
1 | Default VLAN | Static | Active
2 | Blue | Static | Active
