CISCO-ETHERNET-FABRIC-EXTENDER-MIB
The MIB module for configuring one or more fabric extenders to connect into a core switch. Since fabric extenders might not be manageable entities, this MIB is assumed to be instrumented on the core switch. A fabric extender may be hardwired or preconfigured with a list of uplink ports. These uplink ports are used to connect to a core switch. A fabric extender is assumed to be directly connected to its core switch. Each physical interface on the core switch is assumed to be connected to one and only one fabric extender. When an extender powers up, it runs a link local discovery protocol to find core switches. The extender puts all available self identification in its discovery report. The core switch, depending on configuration, uses the extenders identification to accept or deny an extender from connecting. A fabric extender may be connected to different core switches via different uplink ports. In that case, each core switch's instance of the MIB may refer to the same extender. Ports on core switch used to connect to extenders are known as Fabric ports. A fabric port may be a physical interface or a logical interface such as an EtherChannel. An extender may connect into a core switch via more than one fabric port. Non fabric ports on an extender are typically used to connect hosts/servers.
