The password for encrypting packets is configured.
CAUTION
If simple is selected, the password is saved in the configuration file in plain text. In this case,
users at a lower level can easily obtain the password by viewing the configuration file. This
brings security risks. Therefore, it is recommended that you select cipher to save the password
in cipher text.

2.6.9 (Optional) Setting the Timeout of Hello Packets
If the backup device in an E-Trunk does not receive any hello packet from the peer device within
the timeout interval, it becomes the master device. The timeout interval here refers to the timeout
interval contained in the hello packets sent by the peer device rather than that set on the local
device.
Context
Do as follows on the member devices of the E-Trunk.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
e-trunk e-trunk-id
The E-Trunk view is displayed.
Step 3 Run:
timer hello hello-times
The interval for sending Hello packets is set.
By default, the value of hello-times is 10. Since the unit is 100 ms, the interval for sending hello
packets is 1s.
Step 4 Run:
timer hold-on-failure multiplier multiplier
The time multiplier for detecting Hello packets is set.
The peer device checks the timeout interval contained in the received packet to check whether
the local device times out. If the peer device is the backup and does not receive hello packets
from the local device within the timeout interval, the peer device becomes the master.
Timeout interval = Interval for sending hello packets x Time multiplier. It is recommended that
you set the time multiplier to at least 3.
