CISCO-WRED-MIB

1997-07-18

Cisco WRED MIB - Overview Cisco Weighted Random Early Detection/Drop is a method which avoids traffic congestion on an output interface. Congestion is detected by computing the average output queue size against preset thresholds. WRED support are on the IP fast switching and IP flow switching only. It does not apply to IP process switching. This MIB incorporates objects from the Cisco WRED line interfaces. Its purpose is to provide Weighted Random Early Detection/Drop packet configuration and packet filtering information. WRED are configured/enabled through the CLI command. Defaults configuration values are assigned and values can be modified through additional CLI commands.

Table details

cwredConfigGlobTable

1.3.6.1.4.1.9.9.83.1.1.1

Index: ifIndex

A table of WRED global configuration variables.

from IF-MIB

ifIndex

InterfaceIndexA unique value, greater than zero, for each interface or interface sub-layer in the managed system. It is recommended that values are assigned contiguously starting from 1. The value for each interface sub-layer must remain constant at least from one re-initialization of the entity's network management system to the next re-initialization. (1..2147483647) · Integer32 · hint d

A unique value, greater than zero, for each interface. It is recommended that values are assigned contiguously starting from 1. The value for each interface sub-layer must remain constant at least from one re-initialization of the entity's network management system to the next re- initialization.

cwredConfigGlobQueueWeight

1.3.6.1.4.1.9.9.83.1.1.1.1.1

Integer32

The decay factor for the queue average calculation. Numbers are 2's exponent up to 16. The smaller the number, the faster it decays.

cwredConfigPrecedTable

1.3.6.1.4.1.9.9.83.1.1.2

Index: ifIndex · cwredConfigPrecedPrecedence

A table of WRED configuration values with respect to the IP precedence of packets.
