What are the precautions for delivering dynamic VLANs

19

Dynamic VLANs are delivered in the following ways:
1. VLAN IDs
2. VLAN names
To deliver dynamic VLANs based on VLAN names, configure the description that specifies the VLAN name in the VLAN view.

Do S series switches support dynamic VLAN delivery through the RADIUS server
Dynamic VLAN delivery through the RADIUS server is to deliver VLAN attributes through the RADIUS server to dynamically authorize online users. For S series switches (except the S1700), the S2700SI and S2710SI running V100R006 do not support this function. However, other switch models running V100R006 and all switch models running versions later than V100R006 support this function.

GVRP mechanism on S series switch
The Generic Attribute Registration Protocol (GARP) provides a mechanism to propagate attributes so that a protocol entity can register and deregister attributes. The GARP VLAN Registration Protocol (GVRP) is used to register and deregister VLAN attributes. A manually configured VLAN is a static VLAN, and a VLAN created through GVRP is a dynamic VLAN. VLAN registration: adds a port to a VLAN. When a port receives a VLAN attribute declaration, it registers the VLAN specified in the declaration. VLAN deregistration: removes a port from a VLAN. When a port receives a VLAN attribute declaration, it deregisters the VLAN specified in the declaration.
