Equal Cost Multi-Path (ECMP)
Equal cost multi-path (ECMP) is supported on the Dell Networking OS.
ecmp-group
Provides a mechanism to monitor trac distribution on an ECMP link bundle. A system log is generated when the standard deviation of
trac distribution on a member link exceeds a dened 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 identier number for the ECMP group. The range is from 2 to 64.
interface Enter the following keywords and slot/port to add the interface to the ECMP group:
• 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the
slot/port information.
link-bundle-monitor Enter the keywords link-bundle-monitor to enable link bundle monitoring.
