5.2.2 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.
5.2.3 Environment monitoring
By monitoring key environment parameters of the SNR-S212i-8POE, such as temperature
and voltage, you can take measures accordingly to avoid faults.
5.2.4 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.
RMON is an extension of SNMP, but ROMN is more active and efficient for monitoring
remote devices. The administrator can quickly trace faults generated on the network, network
segments or devices.
At present, RMON implements four function groups:
Statistic group
History group
Alarm group
Event group
5.2.5 System log
The system log refers that the SNR-S212i-8POE records the system information and
debugging information in a log and sends the log to the specified destination. When the SNR-
S212i-8POE fails to work, you can check and locate the fault easily.
The system information and some scheduling output will be sent to the system log to deal
with. According to the configuration, the system will send the log to various destinations. The
destinations that receive the system log are divided into:
Console: send the log message to the local console through Console interface.
Host: send the log message to the host.
Monitor: send the log message to the monitor, such as Telnet terminal.
File: send the log message to the Flash of the device.
Buffer: send the log message to the buffer.
SNMP server: convert logs into Trap to output them to the SNMP server.
5.2.6 Optical module monitoring
The SFP optical module is an optical transceiver. SFP provides a performance monitoring
method for the SNR-S212i-8POE. By analyzing monitoring data provided by SFP, the
network administrator can predict the life of the SFP module, isolate system fault, and verify
module compatibility during on-site installation.
Each SFP provides five performance parameters:
