Parameters
recover: Recovers all member devices.
Description
Use the auto-build command to start an automatic cluster building process.
You can execute this command on a management device or on a switch to be configured as a
management device.
When you execute this command on a candidate device, you are prompted to enter a cluster name to
build a cluster. The candidate device will automatically become the management device of the cluster.
Then, the management device will collect candidate devices and add them to the cluster automatically.
When you execute this command on a management device, the system directly collects candidate
devices ant automatically adds them to the cluster.
The recover keyword is used to recover a cluster. After you execute the auto-build recover command,
the system looks for the down members in the member list and add them to the cluster again.
Note that, the collection of candidate/member devices are based on NTDP. Therefore, you must first
enable NTDP. In addition, you can use the ntdp hop command in system view to change the collection
range.
When the system automatically adds a device to the cluster, if the user password configured for the
device is different from that of the management device, the device cannot be added to the cluster.
After a cluster is built automatically, ACL 3998 and ACL 3999 will automatically generate a rule
respectively to prohibit packets whose source and destination addresses are private IP addresses
of the cluster from being sent to or received from the public network. The two ACL rules will be
automatically applied to all ports of the cluster members.
After a cluster is built automatically, ACL 3998 and ACL 3999 can neither be configured/modified
nor removed.
