Managing ECMP Group Paths
To avoid path degeneration, congure the maximum number of paths for an ECMP route that the L3 CAM can hold. When you do not
congure the maximum number of routes, the CAM can hold a maximum ECMP per route.
To congure the maximum number of paths, use the following command.
NOTE: For the new settings to take eect, save the new ECMP settings to the startup-cong (write-mem) then reload the
system.
• Congure the maximum number of paths per ECMP group.
CONFIGURATION mode.
ip ecmp-group maximum-paths {2-64}
• Enable ECMP group path management.
CONFIGURATION mode.
ip ecmp-group path-fallback
Example of the ip ecmp-group maximum-paths Command
Dell(conf)#ip ecmp-group maximum-paths 3
User configuration has been changed. Save the configuration and reload to take effect
Dell(conf)#
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 link-bundle (as
opposed to a single link within the bundle) exceeds 60%.
1 Create a user-dened 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
3 Enable 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.
