Licensing Requirements and Limitations for VPLS

Other network elements are not required.

VPLS is a basic feature of a switch and is not under license control.

Only the following switch models support VPLS:

S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731S-H, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730S-H, and S6730-H

For details about software mappings, visit Hardware Query Tool and search for the desired product model.

Do not add the PW to VLAN 1. If the PW is added to VLAN 1, the AC joins VLAN 1 in untagged mode and VLAN tags of packets are removed.
If an interface is used as a VPLS AC-side interface and a multicast inbound interface at the same time, multicast data cannot be forwarded normally on this interface. (S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-HI, S6730-H, S6730S-H, S6730-S, and S6730S-S do not have this restriction.)
After receiving Layer 2 protocol packets such as STP, VBST, SMLK, LDT/LBDT, LACP, 3AH, 1AG, Y.1731, HGMP, LLDP, DLDP, GVRP, HVRP, DAD, LNP, VCMP, and BFD packets from an AC interface, a PE device determines whether it needs to process the packets. If not (for example, Layer 2 protocols are disabled), the PE device transparently transmits the Layer 2 protocol packets through the VPLS.
When the L2VPN function is configured on a switch and the AC-side outbound interface is configured as an Eth-Trunk interface, only the S5720-HI, S5730-HI, S5731-H, S5732-H, S5731S-H, S6720-HI, S6730S-H, and S6730-H running V2R13C00 and later versions support IP address-based load balancing.
If the PW-side routing interface is a Layer 3 interface switched by the undo portswitch command, the AC-side interface cannot be a Layer 3 routing interface or its sub-interface belonging to a Layer 3 interface; otherwise, traffic fails to be forwarded. This rule applies to S5710-EI, S5720-EI, S6720-EI, and S6720S-EI.
