HP 5820X Switch - Enabling Management VLAN Auto-Negotiation

You can press Ctrl+C anytime during the adding process to exit the cluster auto-establishment process.
However, this only stops adding new devices into the cluster, and devices already added into the cluster
are not removed.
To manually establish a cluster:

1. Enter system view.

2. Specify the management
VLAN.

Optional.
By default, VLAN 1 is the
management VLAN.
3. Enter cluster view.

Use either approach.
By default, the device is not the
management device.
CAUTION:
Handshake packets use UDP port 40000. For a cluster to be established successfully, make sure that the
port is not in use before establishing it.
Enabling management VLAN auto-negotiation
The management VLAN limits the cluster management range. If the device discovered by the
management device does not belong to the management VLAN, meaning that the cascade ports and the
ports connecting with the management device do not allow the packets from the management VLAN to
pass, and the new device cannot be added to the cluster. Through the configuration of the management
VLAN auto-negotiation function, the cascade ports and the ports directly connected to the management
device can be automatically added to the management VLAN.
NOTE:
When the management VLAN auto-negotiation is enabled, the ports connecting member devices
automatically change to hybrid ports, and permit the packets of the management VLAN to pass
through tagged.
• If a port was an access or a trunk port, after changed to a hybrid port, the port does not permit the
packets of any other VLAN except the management VLAN to pass through.
• If a port was a hybrid port, the link type change process does not affect the permitted VLANs. The
only change is that the packets of the management VLAN are permitted to pass through tagged.
Before enabling this function, check the link types of ports connecting member devices and the VLANs
whose packets are permitted to pass throu
