DOM values
« on: September 14, 2019, 11:57:29 pm »
Every type of fiber interface have there dampening values..   Can we handle different type of SFPs with correct values

Yes, by adding the different types (as reported by switch) and thresholds to nedi.conf:

dom-alert   CCM-1241   3   -10   3   -12   default-settings

Hello,

Quick question : I would like to add the different type of SFP I have in my network.
Here is the information in my nedi.conf :

# Digital Optical Monitoring using type of transceiver to set transceiver based alert thresholds.
# Values within 3dBm generate warnings. The signal levels are stored in the transceiver's module
# entry (RX=FW,TX=SW) and set its status accordingly.
#
#      type      TX-hi   TX-lo   RX-hi   RX-lo   description (replaces module description)
;dom-alert   default      3   -10   3   -12   default-settings
dom-alert   GLC-SX-MMD    -3   -9.5   0   -17
dom-alert    GLC-LH-SMD   -3   -9.5   -3   -19
dom-alert   SFP-10G-LR   -0.5   -8.2   -0.5   -14.4
;dom-alert    1000BaseSX   -3    -9.5    0    -17

I do not understand why I have a warning ?



Thank you

Sorry, for the delay :)

If a value is within 3dbm (RX) or 1dbm (TX) of the threshold, a warning state is issued. You can adapt nedi.conf, if you want to get rid of them (or modify $wt in the CheckOptic() function in libmisc.pm).

I have cisco WS-C3850-12S-E

show interface transceiver details showing me such table:

Gi1/0/9      -7.1                    2.0       -0.0      -27.9      -30.0


But, in Devices-Status in Modules table i see such:



Could you help me, why these shown values are multiplied by 10, and becuse of these are alerted?

Cause was the wrong configuration. I just used default configuration.

It can be solved using Other-Defgen from Device-Status. Then in Modules section in Optics monitor by changing divide factor I set needed value.

Thanks for not giving up ;) Feel free to send the .def by clicking on the little mail icon in Defed...

Oh yeah! That OIDs is quiet tough thing!

By the way, where can I download finished .def's for Nedi? I interested especially for defs for some uncommon cisco devices.

I plan a new tutorial. You can find all working .defs in the distribution and some additional ones here in the forum...
