Any configuration changes made locally on the switch won't be synchronized with Sophos Central. We recommend making changes from the Sophos Central control panel instead.

GVRP

GARP VLAN Registration Protocol (GVRP) is an IEEE 802.1Q-compliant protocol for automatically managing VLAN membership. GVRP uses join and leave messages to manage the switch's VLAN membership. You can manage the switch's GVRP settings on the GVRP tab.

Global settings

Click Turned on or Turned off, and click Update to turn GVRP on or off.

Port settings

You can see the following information about the switch's GVRP settings:

  • Port: Shows the port to which the GVRP settings apply.
  • Status: Shows whether GVRP is turned on or off for the specified port.
  • Restricted VLAN: Shows whether the port is in restricted VLAN mode. In this mode, the port only learns VLANs that are already configured on the switch. It ignores join messages for all other VLANs.
  • Join time: Shows the configured join time. This controls how long a switch waits before sending GVRP Join messages to advertise VLAN membership.
  • Leave time: Shows the configured GVRP Leave time. This controls how long a switch waits before sending GVRP Leave messages to deregister VLAN membership.
  • Leave-all time: Shows the configured GVRP LeaveAll time. This controls how often the switch sends GVRP LeaveAll messages to refresh VLAN registration information.

To change GVRP settings, select the ports you want to change and click Edit.

Click Apply to save your changes.
