ecmp-group
Provides a mechanism to monitor traffic distribution on an ECMP link bundle. A system log is generated when the standard deviation of
traffic distribution on a member link exceeds a defined threshold.
Syntax
ecmp-group {ecmp-group-id interface interface | link-bundle-monitor}
To remove the selected interface, use the ecmp-group no interface command.
To disable link bundle monitoring, use the ecmp-group no link-bundle-monitor command.
Parameters
ecmp-group ID Enter the identifier number for the ECMP group. The range is from 2 to 64.
interface Enter the following keywords and the interface information to add the interface to the
ECMP group:
• For a 1-GigabitEthernet interface, enter the keyword GigabitEthernet then the
slot/port information.
• For a 1-GigabitEthernet interface, enter the keyword GigabitEthernet then the
slot/port information.
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then
the slot/port information.
• For a LAG interface, enter the keywords port-channel then the slot/port
information.
