Link Layer Discovery Protocol (LLDP) stations that connect to a local area network (LAN) advertise the station capabilities to each other, allowing the discovery of physical topology information for network management. When the system enables a switch as a Fabric Attach (FA) server in the Shortest Path Bridging (SPB) network, it receives LLDP messages from the FA Client and the FA Proxy devices using the LLDP Fabric Connect Type-Length-Value (TLV). For more information, see LLDP Fabric Connect TLV.
Following are the steps to create an Intermediate-System-to-Intermediate-System (IS-IS) adjacency between Auto-sense and non-Auto-sense VOSS switches, such as VSP 8600 Series or switches running releases that do not include Auto-sense support. For feature support information, see Fabric Engine and VOSS Feature Support Matrix.
