Switch stacking is a technology and technique where two or more switches are physically connected and configured to act as a single unit. Switch stacking can be used with EtherChannel to provide redundancy for the Metasys BAS Aggregation switches, allowing communication within the Metasys BACnet/IP Network to continue in the event of the failure of one of the Metasys BAS Aggregation switches. A similar configuration between the Metasys BAS Aggregation switches and the firewall/gateway or the IT network could also be configured to allow communication between the Metasys BACnet/IP network and the outside network to continue in the case of a Metasys BAS Aggregation switch failure.
