[ Need Help T_T ] finding OIDs for Delay RTT, RX Optical Power and Tx Optical Power

Need help from anyone who knows about the following.

I’m trying to find 3 OIDs for Extreme Networks switches X460 and X670.

I have found other OIDs with the names below, but none of them worked:

1. Delay RTT

- other OID: 1.3.6.1.4.1.15007.1.3.1.3.7.1.3

- name: mefSoamDmThresholdMaxFrameDelayRoundTripThreshold

2. RX Optical Power

- other OID: 1.3.6.1.4.1.1588.3.1.8.1.1.1.6

- name: bcsiOptMonLaneRxPowerStatus

3. Tx Optical Power

- other OID: 1.3.6.1.4.1.1588.3.1.8.1.1.1.3

- name: bcsiOptMonLaneTxPowerStatus

* more information

For CPU Utilization and Memory Utilization, the switches work with the following OIDs:

- 1.3.6.1.4.1.1916.1.32.1.2.0

- 1.3.6.1.4.1.1916.1.32.2.2

Thanks in advance.

It's a mess really. The only one that worked for me is the standardized .1.3.6.1.2.1.99, a.k.a. entitySensorValueGroup in ENTITY-SENSOR-MIB. Extreme's own ENTERASYS-ENTITY-SENSOR-MIB-EXT-MIB::etsysEntitySfpSensorTxDdm etc. works for some things but finding which interface is which is a nightmare.

entitySensorValueGroup splits the values for each interface so interface 52 in a 5420 has indexes 847-850 for different values. This goes against all other MIX practices where you have an interface index attached to a certain value. Here is some output from a 5420:

ENTITY-SENSOR-MIB::entPhySensorType.847 = INTEGER: voltsDC(4)
ENTITY-SENSOR-MIB::entPhySensorType.848 = INTEGER: amperes(5)
ENTITY-SENSOR-MIB::entPhySensorType.849 = INTEGER: watts(6)
ENTITY-SENSOR-MIB::entPhySensorType.850 = INTEGER: watts(6)

ENTITY-SENSOR-MIB::entPhySensorScale.847 = INTEGER: units(9)
ENTITY-SENSOR-MIB::entPhySensorScale.848 = INTEGER: milli(8)
ENTITY-SENSOR-MIB::entPhySensorScale.849 = INTEGER: micro(7)
ENTITY-SENSOR-MIB::entPhySensorScale.850 = INTEGER: micro(7)

ENTITY-SENSOR-MIB::entPhySensorValue.847 = INTEGER: 3
ENTITY-SENSOR-MIB::entPhySensorValue.848 = INTEGER: 23
ENTITY-SENSOR-MIB::entPhySensorValue.849 = INTEGER: 720
ENTITY-SENSOR-MIB::entPhySensorValue.850 = INTEGER: 518

As the values are in µW, you need to calculate the dBm value if that's what you're after. Above, 518 µW => 10*(log 0.518) = -2,85 dBm (which corresponds to what the switch reports).
