The S5700-LI can use the GARP VLAN Registration Protocol (GVRP) to implement dynamic distribution,
registration, and propagation of VLAN attributes. GVRP reduces manual configuration workload and
ensures correct configuration. Additionally, the S5700-LI supports MUX VLAN, which involves a principal
VLAN and multiple subordinate VLANs. Subordinate VLANs are classified into group VLANs and separate
VLANs. Ports in the principal VLAN can communicate with ports in subordinate VLANs. Ports in a
subordinate group VLAN can communicate with each other, whereas ports in a subordinate separate
VLAN can communicate only with ports in the principal VLAN. The S5700-LI also supports VLAN Central
Management Protocol (VCMP) andVLAN-Based Spanning Tree (VBST) protocol.
