7.2.2 Traceroute

Traceroute is used to discover the real route taking by the packet to transmit to the destination.
Although the Ping feature can test the connectivity, it cannot record all network devices on
the route limited by the IP head. Traceroute can be used to test routing information from the
source host to the destination host.

7.2.3 Enviromental monitoring

Environmental monitoring is to monitor key parameters of the device, including, temperature
and voltage, etc. When those parameters are abnormal, you can take corresponding
measurements to prevent failures.

7.2.4 RMON management

Remote Network Monitoring (RMON) is a standard developed by the Internet Engineering
Task Force (IETF). RMON is used to monitor network data through different Agents and
NMS, and it mainly realizes statistical and alarm reporting functions. RMON is an extension
of SNMP. However, compared with SNMP, ROMN is more active and efficient for
monitoring remote devices. The administrator can quickly trace faults generated on the
network, network segment, or device.
At present, RMON implements four function groups: statistic group, historical group, alarm
group, and event group.

7.2.5 System log

System log refers that the device records the system information and debugging information
in a log and sends the log to the specified destination. When the device fails, you can check
and locate the fault easily.
The system information and some debugging output will be sent to the system log to process.
According to the configuration, the system will send the log to various destinations. The
destinations that receive the system log are divided into:






7.2.6 Watchdog

Through configuring the watchdog feature, you can prevent the system program from dead
circulation caused by uncertain faults so as to improve the stability of system.

7.2.7 Port mirroring

Port mirroring refers to mirroring some packets of a specified source interface to the
destination interface, i.e. the monitor port, without affecting forwarding of normal packets.
You can monitor packets sending and receiving on one interface by this function and analyze
the relevant network status or fault conditions.
Host: send the log message to the host.
Monitor: send the log information to the monitor, such as Telnet terminal.
File: send the log information to the Flash of the device.
Buffer: send the log information to the buffer.
SNMP server: transfer the log information into Trap and send it to the SNMP server.
