WRED configuration example
Network requirements
Apply a queue-based WRED table to interface GigabitEthernet 2/1/1.
Configuration procedure
# Enter system view
<Sysname> system-view
# Create a queue-based WRED table named queue-table1, and modify the lower and upper thresholds
and drop probability for each queue.
NOTE:
Configure the lower and upper thresholds for each queue in the WRED table depending on the interface
buffer size, which varies by interface type.
