D.M.I Dynamic Management Interface

DMI Dynamic Management Interface

The D.M.I (Diagnostic Monitoring Interface) has been developed for monitoring the S.F.P  (Short Form Pluggable ) in Fibre ports. Typically used on Ethernet Switches and Routers DMI allows network managers to monitor the fibre and be forewarned of impending problems, in particular the following parameters are monitored

  1. Temperature
  2. Voltage
  3. Current
  4. Transmitting power
  5. Receiving power

If the real time values, of the respective ports reach the threshold of the connected transceiver, the system will shut down the device or send an e-mail or SNMP Trap to the network manager or network engineer.

Temperature

High Warning– Set a threshold temperature to send a warning  e-mail or shut the port down if the temperature reaches this level.
High Alarm – Set a threshold temperature to send an alarm or  e-mail or shut the port down if the temperature reaches this level.

Status

Status – current temperature of the fibre port
Low warning – Set a threshold temperature to send a warning  e-mail or shut the port down if the temperature drop to this level.
Low Alarm – Set a threshold temperature to send an alarm or  e-mail or shut the port down if the temperature drops to this level.

Voltage

High Warning– Set a threshold voltage to send a warning e-mail or shut the port down if the voltage reaches this level.
High Alarm – Set a threshold voltage to send an alarm or  e-mail or shut the port down if the voltage reaches this level.
Status – current voltage of the fibre port
Low warning – Set a threshold voltage to send a warning  e-mail or shut the port down if the voltage drops to this level.
Low Alarm – Set a threshold voltage to send an alarm e-mail or shut the port down if the voltage drops to this level.

Current

High Warning– Set a threshold current to send a warning e-mail or shut the port down if the current reaches this level.
High Alarm – Set a threshold current to send an alarm or  e-mail or shut the port down if the current reaches this level.
Status – current consumption of the fibre port
Low warning – Set a threshold voltage to send a warning  e-mail or shut the port down if the  current drops to this level.
Low Alarm – Set a threshold voltage to send an alarm e-mail or shut the port down if the current drops to this level.

TX Power

High Warning– Set a threshold Tx Power to send a warning e-mail or shut the port down if the Transmit power of the SFP reaches this level.  May indicate a failing SFP or possible too high voltage to the switch)
High Alarm – Set a threshold Tx Power to send an alarm or e-mail or shut the port down if the Transmit power of the SFP reaches this level. (May indicate a failing SFP or possible too high voltage to the switch)
Status – current transmit power of the fibre port
Low warning – Set a threshold Tx Power to send a warning e-mail or shut the port down if the Transmit power of the SFP reached this level. (May indicate a failing SFP or possible voltage drop to the switch)
Low Alarm – Set a threshold Transmit power to send an alarm e-mail or shut the port down if the Transmit power drops to this level. (May indicate a failing SFP or possible voltage drop to the switch)

RX Power

High Warning– Set a threshold Rx power to send a warning e-mail or shut the port down if the Receive power of the SFP reaches this level.  May indicate the other end of the link is sending at too high a level.
High Alarm – Set a threshold Rx power to send an alarm or  e-mail or shut the port down if the Receive  power of the SFP reaches this level. May indicate the other end of the link is sending at too high a level.
Status – current Receive power of the fibre port
Low warning – Set a threshold voltage to send a warning e-mail or shut the port down if the Receive power of the SFP reached this level. (May indicate failing fibre, poor splice joins, a failing SFP at the remote end of the fibre)
Low Alarm – Set a threshold Transmit power to send an alarm e-mail or shut the port down if the Transmit power drops to this level.  (May indicate failing fibre, poor splice joins, a failing SFP at the remote end of the fibre)
