Enabling Management Vlan Auto-Negotiation - HP 5820X Switch Configuration Manual

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:
To do...
1. Enter system view.
2. Specify the management
VLAN.
3. Enter cluster view.
4. Configure the private IP
address range for member
devices.
5. Establish a
cluster.
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 through to avoid influence to your network due to link type change
of ports.
Use the command...
system-view
management-vlan vlan-id
cluster
ip-pool ip-address { mask | mask-
length }
Manually
establish a build cluster-name
cluster
Automatically
establish a auto-build [ recover ]
