VPC (also known as MLAG) enables a LAG to be created across two independent switches, so that some member ports of a VPC can reside on one switch and the other members of a VPC can reside on another switch. The partner device on the remote side can be a VPC-unaware unit. To the unaware unit, the VPC appears to be a single LAG connected to a single switch.
In the MLAG pair, the primary handles the LACP state machine for the MLAG member ports and STP state machine for the MLAG interface. The administrator must view the port-channel details of the MLAG member ports and Spanning Tree details of the MLAG interface on the primary.
Note: This feature is only supported by the LANCOM XS-6128QF.
