■ POS interfaces do not support WRED configuration.
■ In the above table, when the exponent for calculating average queue length
and other parameters for the WRED table are configured, the outgoing ports
of 3C17526, 3C17532, and 3C17538 modules support four queues, that is,
the queue-value argument is in the range of 0 to 3; this argument is in the
range of 0 to 7 for the other modules.
Displaying and
Maintaining WRED
Follow these steps to display and maintain WRED:
