Description
Cisco WRED MIB - Overview Cisco Weighted Random Early Detection/Drop (WRED) is a method which avoids traffic congestion on an output interface. Congestion is detected by computing the average output queue size against queue thresholds, which can be configured either per IP precedence or differentiated services code point (DSCP) based. WRED support are on the IP fast switching and IP flow switching only. It does not apply to IP process switching. The purpose of this MIB is to provide Weighted Random Early Detection/Drop packet configuration and packet filtering information. This MIB provides the WRED information about the transmit (Tx) side and receive (Rx) side of the modules, for the managed systems that support WRED on both transmit side and receive side.
