GARP VLAN Registration Protocol (GVRP) Statistics on ESW2-350G Series Managed Switches

Objective

The GARP VLAN Registration Protocol (GVRP) maintains and sends VLAN information on switches. A packet of GARP may contain several messages and further attributes such as classifications of these messages. The VLAN ID is given in the GARP packet using which the VLAN is recorded and also the port or LAG from which it can be accessed. An attribute internally has length event and a value. The sent and received frames of the GVRP from a port or LAG are displayed in the GVRP page. These Statistics are displayed when GVRP is enabled globally and on a port or LAG. GVRP must be enabled before you are able to view the statistics. To enable GVRP refer to the article Generic VLAN Registration Protocol (GVRP) Settings Configuration on ESW2-350G Switches.

This article explains the statistics of the GVRP in ESW2 350G Series Managed Switches.

Applicable Devices

• ESW2-350G-52
• ESW2-350G-52DC

Software Version

• 1.2.9.44

GVRP Statistics

Step 1. Log in to the web configuration utility and choose Status and Statistics > GVRP. The GVRP page opens:

Step 2. At Interface click the appropriate radio button and choose the respective Port or LAG from the drop-down list for which GVRP statistics are to be displayed. The interface options available are:

• Port — Select the radio button of Port and choose a port from the listed 1 to 52 ports for which the statistics are to be displayed.

• LAG — Select the radio button LAG and choose from the list, the LAG for which the statistics are to be displayed. To define a member or candidate port on a LAG refer to the article Link Aggregation Management on ESW2-350G Switches.

Step 3. At Refresh rate click the desired time period for every refresh of the GVRP statistics.

Note: The Received and Transmitted Statistics displays the following fields:

• Join Empty — The attributes which are not registered on the device and are sent to be declared.

• Empty — The number of empty packets that can take the Join in and Join empty packets.

• Leave Empty — Displays GVRP leave empty packets that are received and transmitted.

• Join In — Displays the number of GVRP join in packets sent where the attribute has been declared.

• Leave In — Displays GVRP leave in packets sent to remove attributes registered on the device.

• Leave All — Displays GVRP Leave All packets received and transmitted.

The GVRP Error Statistics area which determine the GVRP error counters are mentioned further in the statistics. The attributes mentioned are as follows:

• Invalid Protocol ID — Total packets with ID errors.

• Invalid Attribute Type ID — Total packets with message errors.

• Invalid Attribute Value — Total packets with attribute value that is the VLAN ID error

• Invalid Attribute Length — Total packets with Attribute length errors.

• Invalid Events —.Total event error packets.
