SNMP Statistics
The SNMP Statistics dialog box provides statistical information on Simple Network Management
Protocol (SNMP).
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. The agent is the network management software module residing in the
managed device. The network management system runs the SNMP application that controls the
managed devices and monitors their status. Four primary operations (Set, Get, Get Next, and Trap)
are performed using SNMP and monitored for display on this screen of statistics.
You can use these statistics as a troubleshooting aid should you have a problem communicating with
the MultiFRAD from your SNMP manager.
WAN Statistics
The WAN Port Statistics dialog box provides statistical information regarding the MultiFRAD’s
Composite Link port, including the number of packets transmitted/received, and to transmit, and the
number of bytes transmitted/received.
This dialog box monitors the traffic on the MultiFRAD’s composite link (WAN) port. The Statistics that
fall into the “Others” category relate to the physical layer between the MultiFRAD and the link device;
i.e., the CSU/DSU. These statistics can be helpful in troubleshooting suspected problems in the
physical layer; e.g., the WAN port itself, the link device (CSU/DSU), and any associated cabling.
