4.1.4.5 RMON
RMON (Remote Network Monitoring) is for statistics and alarm function. It is applied for remote
monitoring and management in network. Statistics is the function that the managed device can
periodically or continuously record the flow information of the network segment which the port
connects to, for example, the packet quantity received by the network segment in a period of
time. Alarm function is that the managed device can monitor the value of the specific MIB
variable, and when the value reaches the alarm threshold (for example, the port rate reached
the specific value, or the ratio of broadcasting packet reaches the specific value), it can
automatically record the log, and send Trap packet to the management device.
Statistics
The statistics group regulates that the system continuously records the different types of flow
information from the port (only supports Ethernet port currently) and stores the statistics result
in the Ethernet statistical table (etherStatsTable), and the management can check the result
conveniently. The statistics information contains the quantity of network conflicts, quantity of
CRC verification error message, quantity of data packet too small or too large, quantity of
broadcasting packet or multicasting packet, the received byte count, and the quantity of
received packet.
After creating the statistics table in the specific port, the statistics table records the packet
quantity from the current port. The statistics result is the continuously accumulated value.
Step 1 Select Advanced > Configuration > Security > RMON.
The Statistics interface is displayed. See Figure 4-36.
Step 2 Click Add New Entry.
A new record is added. See Figure 4-37.
Description
Select the view type from the drop-down list to set whether the
object decided by OID of MIB subtree and subtree mask is
included in the view type.
Input the OID of MIB subtree root node (for example, 1.4.5.3.1), or
the name (for example, system).
OID of MIB subtree indicates the node position in the MIB tree, and
it can only identify one object in the MIB library.
