The user has the option of configuring each queue to one of the following attributes (the
acceptable ranges are shown in brackets):
Column Description
Service Rate [ -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 Preferences 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) [0–100] – 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) [0–99] – 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)) [0–99] – In case of congestion, the WRED
is applied after the queue depth exceeds the configured percentage value
assigned for the Drop Precedence value b011.
