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 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.
Configuration guidelines
When the management VLAN auto-negotiation is enabled, the ports connecting member switches change as follows:
If a port was an access port, after changing to a hybrid port, the port does not permit the packets of any other VLAN to pass through except the management VLAN, which passes as tagged.
If a port was a trunk or a hybrid port, the link type change process does not affect the port type and the permitted VLANs. The only change is permit the packets of the management VLAN to pass through tagged only for a hybrid port.
Before enabling this function, check the link types of ports connecting member switches and the VLANs whose packets are permitted to pass through to avoid influence to your network due to link type change of ports.
