Cisco Cisco ASR 5000 Technical Manual

include pre−configured default values.

Major: This trigger level defines the major threshold values for different triggers. The values of this
trigger level should be greater than the minor threshold and less than the critical. The default value is
zero.

•

Minor: This trigger level defines the minor threshold values for different triggers. The values of this
trigger should be least among all three thresholds. The default value is zero.

•

The three threshold values can be defined for all of the parameters/triggers that are mentioned in the previous
section. Here is the CLI syntax that is used in order to define the thresholds for the different parameters:

congestion−control threshold license−utilization { critical <percent> | major

<percent>t | minor <percent> }

congestion−control threshold max−sessions−per−service−utilization { critical

<percent> | major <percent> | minor <percent> }

congestion−control threshold message−queue−utilization { critical <percent> |

major <percent> | minor <percent> }

congestion−control threshold message−queue−wait−time { critical <time> |

major <time> | minor <time> }

congestion−control threshold port−rx−utilization { critical <percent> | major

<percent> | minor <percent> }

congestion−control threshold port−specific { <slot/port> [ tx−utilization {

critical <percent> | major <percent> | minor <percent> ] [ rx−utilization {

critical <percent> | major <percent> | minor <percent> } | all { critical

<percent> | major <percent> | minor <percent> } }

congestion−control threshold port−tx−utilization { critical <percent> | major

<percent> | minor <percent> }

congestion−control threshold service−control−cpu−utilization { critical

<percent> | major <percent> | minor <percent >}

congestion−control threshold system−cpu−utilization { critical <percent> |

major <percent> | minor <percent> }

congestion−control threshold system−memory−utilization { critical <percent> |

major <percent> | minor <percent> }

congestion−control threshold tolerance { critical <percent> | major

<percent> | minor <percent> }

Note: The critical threshold values for the different parameters (except the license−utilization) use default
values that are the same as those that are described in the previous section. The license−utilization parameter
has a default value for the critical profile as 80%.
