processing strict priority traffic is skewed to be the bandwidth of the
individual TCG divided by the sum of the weights of all WDRR
configured TCGs.
The administrator may configure other parameters to work in conjunction
with the received DCBX configuration, e.g. min-bandwidth per CoS queue
and minimum or maximum bandwidth per TCG.
PC8024 Operation with DCBx
PowerConnect 8024 and 8024F 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 8024 and 8024F 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).
