Configuring the Minimum Thresholds for Maintaining an Active Bundle
The bundle manager uses two configurable minimum thresholds to determine whether a bundle can be brought
up or remain up, or is down, based on the state of its member links.
• Minimum active number of links
• Minimum active bandwidth available
Whenever the state of a member changes, the bundle manager determines whether the number of active
members or available bandwidth is less than the minimum. If so, then the bundle is placed, or remains, in
DOWN state. Once the number of active links or available bandwidth reaches one of the minimum thresholds,
then the bundle returns to the UP state.
To configure minimum bundle thresholds, complete these steps:
SUMMARY STEPS
1. configure
2. interface Bundle-Ether bundle-id
