The Eth-Trunk interface view is displayed.
Only static LACP Eth-Trunks can be added to an E-Trunk.
Step 3 Run:
e-trunk mode { auto | force-master | force-backup }
The working mode of the Eth-Trunk in the E-Trunk is configured.
By default, an Eth-Trunk works in automatic mode in an E-Trunk.
The e-trunk mode command is valid only for an Eth-Trunk in an E-Trunk. When the Eth-Trunk
exits from the E-Trunk, the configuration is cancelled.
When the Eth-Trunk works in automatic mode, the master/backup status of the Eth-Trunk is
determined by the E-Trunk status of the local device and the fault information of the peer Eth-
Trunk.
l If the local E-Trunk is the master, the local Eth-Trunk works in master state.
l If the local E-Trunk is the backup and the peer Eth-Trunk is faulty, the local Eth-Trunk works
When the E-Trunk works properly, changing the interval for sending packets or timeout of hello
packets make the E-Trunk alternate between the master state and the backup state. Therefore, it
is recommended that you set the working mode of a member Eth-Trunk to forcible master/backup
before changing the interval for sending packets or the timeout of hello packets. After new
configurations take effect, you can restore the working mode to automatic.
