Default

64 packets on most platforms

Description

This command allows you to override the default queue size for a class. In WFQ (Weighted Fair Queuing), a queue is created for every class that is defined. If a queue is filled, tail-drop is used for further incoming packets unless WRED is configured (Weighted Random Early Detection). The default of 64 applies on all platforms except those with Versatile Interface Processors (VIPs), where the default is a calculation of bandwidth and buffer memory available.
