Creating an ECMP Group Bundle Within each ECMP group, you can specify an interface. If you enable monitoring for the ECMP group, the utilization calculation is performed when the average utilization of the linkbundle (as opposed to a single link within the bundle) exceeds 60%. 1 Create a user-defined ECMP group bundle. CONFIGURATION mode ecmp-group ecmp-group-id The range is from 1 to 64. 2 Add interfaces to the ECMP group bundle. CONFIGURATION ECMP-GROUP mode interface interface interface tengigabitethernet 0/0 interface port-channel 100 3 Enable the monitoring for the bundle. CONFIGURATION ECMP-GROUP mode link-bundle-monitor enable Modifying the ECMP Group Threshold You can customize the threshold percentage for monitoring ECMP group bundles. To customize the ECMP group bundle threshold and to view the changes, use the following commands. • Modify the threshold for monitoring ECMP group bundles. CONFIGURATION mode link-bundle-distribution trigger-threshold {percent} The range is from 1 to 90%. The default is 60%. • Display details for an ECMP group bundle. EXEC mode show link-bundle-distribution ecmp-group ecmp-group-id The range is from 1 to 64. Viewing an ECMP Group NOTE: An ecmp-group index is generated automatically for each unique ecmp-group when you configure multipath routes to the same network. The system can generate a maximum of 512 unique ecmp-groups. The ecmp-group indices are generated in even numbers (0, 2, 4, 6... 1022) and are for information only. You can configure ecmp-group with id 2 for link bundle monitoring. This ecmp-group is different from the ecmp-group index 2 that is created by configuring routes and is automatically generated. These two ecmp-groups are not related in any way.
