A WRED table contains global WRED parameters. The router supports only queue-based tables for WRED tables. Packets are dropped based on the queue when congestion occurs. A queue-based WRED table can only be applied to Layer 2 ports, and only queue-based WRED tables can be applied to Layer 2 ports.
A WRED table can be applied to multiple interfaces. For a WRED table already applied to an interface, you can modify the values of the WRED table, but you cannot remove the WRED table.
