V400 Virtual Port Extender

Bridge port extenders (BPEs) are devices that do not fully process packets, nor make forwarding or filtering decisions. Instead, they simply receive packets from extended ports and forward packets toward the upstream controlling bridge (an ExtremeXOS-based switch) for L2/L3 processing. This scheme, based on the IEEE 802.1BR specification, is known as extended edge switching.

The V400 Virtual Port Extender offers the following features:
  • 24 or 48 10/100/1000 Base-T ports that provide 10 Gbps copper connectivity.
  • Two or four 1000/10G Base-X SFP+ ports that provide 10 Gbps high-density fiber connectivity.
  • Serial console port.
  • Front panel USB port.
  • PoE+ power on some models.
  • Fixed internal power-supply and fan modules.

All models include either two or four SFP+ ports on the faceplate of each base unit, which can be provisioned either as uplink or cascade ports. This gives administrators the option to create redundant links or downstream cascade ports to other V400 units. The SFP+ ports are the only ones that can be used as uplink ports in a cascading configuration.

The V400 Virtual Port Extender requires that ExtremeXOS (EXOS) version 22.5 (or later) be installed on the switch to which it is attached. For more information about configuring EXOS for use with this equipment, see the ExtremeXOS 22.6 User Guide.
