Enhanced Transmission Selection Operation with
DCBx
PowerConnect M8024-k switches can act as a proxy for ETS information via
the auto configuration mechanism. ETS information received from the
configuration source is transmitted via DCBX to the other auto configuration
peers.
While M8024-k switches are not equipped with a hierarchical scheduler, they
do support the following ETS capabilities:
• Both lossy and lossless service using PFC (may be configured via DCBX).
• Sharing of unused bandwidth with lower priority traffic classes (default
behavior). Sharing of bandwidth is disabled when the minimum
bandwidth assignments sum to 100%.
• WRR or strict-priority scheduling (configured manually).
