Equal Cost Multi-Path (ECMP)
Equal cost multi-path (ECMP) supports multiple "best paths" in next-hop packet forwarding to a
destination device.
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 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet then the slot/port/subport
information.
• For a 40-Gigabit Ethernet interface, enter the keyword
fortyGigE then the slot/port/subport information.
• For a 25-Gigabit Ethernet interface, enter the keyword
twentyFiveGigE then the slot/port/subport
information.
• For a 50-Gigabit Ethernet interface, enter the keyword
fiftyGigE then the slot/port/subport information.
• For a 100-Gigabit Ethernet interface, enter the keyword
hundredGigE then the slot/port information.
• For a LAG interface, enter the keywords port-channel
then the slot/port information.
