  Chapter 4 — MultiFRAD Software IPX is a network layer protocol usually associated with Novell Netware networks. It allows for encapsulation of four different frame types over a single physical LAN connection (provided each frame type has a unique network address): RAW (802.3), LLC (802.2), Ethernet II, and SNAP. These statistics are mostly informational but could be useful for troubleshooting.

• Page 46: Wan Statistics

  MultiFRAD User Guide SNMP is an application layer protocol that facilitates the exchange of management information between network devices. There are three key components in SNMP: the devices that are to be managed, agents, and the network management systems. The managed device is the network device, such as a router.

  Chapter 4 — MultiFRAD Software The Polling Details section lists the various management frames sent and received. For every Status Enquiry Sent, a Status Response should be received from the network. Likewise, for every Full Status Enquiry Sent, there should be one Full Status Response received. The two status enquiry types are used by the FRAD to verify that the frame relay network is operational, and to determine which DLCIs are active.
