The option is provided to configure each queue to one of the following attributes. The
acceptable/valid operating ranges are provided in this section in parentheses, where applicable.
• Service Rate (Kbps) (0.000 / (Tx Data Rate)) – The minimum bandwidth will be served first
among the Assured Forwarding (ASFD) classes in case of bandwidth availability once Class
Selector 7 through Class Selected 1 have been serviced.
• Drop Precedence – ASFD Class 4 through 1 Code Points (b100xx0, b011xx0, b010xx0, and
b001xx0) carry the drop precedence value (xx). In case of network congestion, a Weighted
Random Early Detection (WRED) congestion avoidance algorithm is imposed on these
queues to drop the packets randomly rather than ‘tail drop.’
• Low Drop Precedence (% full) (0 to 100) – In case of congestion, the WRED is applied after
the queue depth exceeds the configured percentage value assigned for the Drop
Precedence value b001.
• Med. Drop Precedence (% full) (0 to 99) – In case of congestion, the WRED is applied after
the queue depth exceeds the configured percentage value assigned for the Drop
Precedence value b010.
• High Drop Precedence (% full) (0 to 99) – In case of congestion, the WRED is applied after
the queue depth exceeds the configured percentage value assigned for the Drop
Precedence value b011.
