GVRP stands for GARP (Generic Attribute Registration Protocol) VLAN Registration Protocol. It's a Layer 2 network protocol, for automatic configuration of switches in a VLAN network.
Each VLAN switch is configured with the VLANs it is part of. GVRP will spread this information and configure the needed VLANs.
So to add a switch to a VLAN, only 1 switch needs to be reconfigured. This is not the case within a standard VLAN, where all switches might need reconfiguration.
XXX - add a brief description of GVRP history
XXX - Add example traffic here (as plain text or Wireshark screenshot).
The GVRP dissector is (fully functional, partially functional, not existing, … whatever the current state is). Also add info of additional Wireshark features where appropriate, like special statistics of this protocol.
There are no GVRP specific preference settings.
XXX - Add a simple example capture file to the SampleCaptures page and link from here. Keep it short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically.
A complete list of GVRP display filter fields can be found in the display filter reference
Show only the GVRP based traffic:
You cannot directly filter GVRP protocols while capturing. However, GVRP packets are sent to the MAC address 01:80:C2:00:00:21, so you can filter on that.
Capture GVRP traffic:
ether dst 01:80:c2:00:00:21
XXX - filter on the LLC DSAP used for STP? Or just do "stp and"?
