  • MFDM – multicast forwarding information base (fib) distribution module (Nexus 7000, programs mrib tables etc)
  • MRIB – Multicast Routing Information Base
  • MTS – Messaging and Transaction System
    The NX-OS message and transaction service (MTS) is a high performance interprocess communications (IPC) message broker that specializes in high availability semantics. MTS handles message routing and queuing between services on and across modules (including across supervisors). MTS facilitates the exchange of messages such as event notification, synchronization, and message persistency between system services and system components. MTS also facilitates and manages message queuing between services and, as a result, can maintain persistent messages and logged messages in queues for access even after a service restart.
  • NFS – Non-stop-forwarding (6500, freezes hardware rib/mrib/cef so frames can forward without the supervisor)
  • QOS – Quality of Service
  • RPF – Reverse path forwarding (mcast)
  • TCAM – Ternary Contant Addressable Memory (used for packet classification and address lookups)
  • URIB – Unicast Routing Information Base
  • VDC – Virtual Device Context
  • VPC – Virtual Portchannel (Nexus, type of multichassis etherchannel with knobs)
  • VRF – Virtual [private network] Routing and Forwarding
