SNR S2940-8G-v2 Switch Configuration Guide
DDM Configuration
• Ensure that SNMP configuration is valid, or else the warning event cannot inform the network
management system.
• Because only some boards and box switches support SFP with DDM or XFP with DDM,
ensure the used board and switch support the corresponding function.
• When using show transceiver command or show transceiver detail command, it cost much
time due to the switch will check all ports, so it is recommended to query the monitoring
information of the transceiver on the specified port.
• Ensure the threshold defined by the user is valid. When any threshold is error, the transceiver
will give an alarm according to the default setting automatically.
