VLANs

To ensure the required operation in any possible application scenario and provide full compatibility with legacy (VLAN-unaware) devices RuggedSwitchTM can be configured to work in a VLAN-unaware mode.

In that mode:

•Frames ingressing a VLAN-unaware switch are not associated with any VLAN

•Frames egressing a VLAN-unaware switch are sent out unmodified, i.e. in the same untagged, 802.1Q-tagged or priority-tagged format as they were received

6.1.9GVRP (Generic VLAN Registration Protocol)

GVRP is an industry-standard protocol designed to propagate VLAN information from device to device. With GVRP, edge switches may be manually configured with all the desired VLANs, and switches on the network learn those VLANs dynamically. An end node, which is GVRP aware, can be plugged into any switch and be connected to that end node's desired VLAN.

When a switch sends GVRP BPDUs out of all GVRP enabled ports, GVRP BPDUs advertise all the VLANs known to that switch (configured manually or learned dynamically through GVRP) to the rest of the network.

When a GVRP enabled switch receives a GVRP BPDU advertising a set of VLANs, the receiving port becomes a member of those advertised VLANs and the switch begins advertising those VLANs out all the GVRP enabled ports (other than the port on which the VLANs were learned).

To improve network security using VLANs, GVRP enabled ports may be configured to prohibit learning any new dynamic VLANs but at the same time allowed to advertise the VLANs configured on the switch.
