Figure 17.3: FRNT can run over aggregated links
Additional information on running RSTP over a link aggregate:
❼ Failover performance: RSTP failover performance may be degraded when
running RSTP over a link aggregate as opposed to using regular links.
❼ Forwarding/Blocking state: An aggregate is forwarding data packets only
if both RSTP and the link aggregate itself determine that it should be in
forwarding state.
❼ RSTP link cost: The RSTP link cost can be configured manually. If ”auto” is
used for cost calculation, WeOS determines the aggregate link cost based
the aggregated bandwidth of the member ports (higher aggregated capacity
gives lower RSTP cost).
❼ Link Up/Down: An aggregate is up if at least one of its member ports are
considered up. An aggregate is down if all its member ports are down.
