Bridge Port Extender General Limitations

  • In the Extended Edge Switching architecture, Layer-2, Layer-3, multicast, and filtering operations take place on the controlling bridge. The controlling bridge switch and attached BPEs constitute a single, extended switch system. Therefore, the Extended Edge Switching system assumes the scale and limits from the specific controlling bridge model (for example, Summit X670-G2) in use. For applicable limits, see the Limits tables in the ExtremeXOS Release Notes.

  • Certain ExtremeXOS features are not supported or have limitations. For information, see ExtremeXOS Feature Compatibility with V400 Virtual Port Extenders.
  • A maximum of 48 attached BPEs is supported.
  • A maximum of 4 levels (tiers) of cascaded BPEs is supported.
  • A maximum of 4 upstream ports (in a LAG) per BPE is supported for V400-48 models. A maximum of 2 upstream ports (in a LAG) per BPE is supported for V400-24 models.
  • Stacking cannot be enabled with VPEX enabled.
