  • 1.  SNMP OID for Switch

    Posted Apr 19, 2023 09:28 AM

    Hello everyone

    I have a switch 3Com Baseline 2952 and I want to monitor Temperature by SNMP.

    I found a few OID items for Temperature, but unfortunately they didn't work.

    My Switch Specification is:

    Device Name : 3CRBSG5293

    3Com Baseline Switch 2952-SFP Plus Software Version Release 1515

    Software Version:  5.2 Release 1515

    I would be very grateful if you could help me with this.

    Hello igumeni
    Thank you for your comment.
    I test very OID but without result.
    only acceptable OID ist a string in this format:   1.3.6.1.4.1.43.45.
    I ran snmpwalk and gather all existing OID. 

     1.3.6.1.2.1.47.1.1.1.1.7.11 = "FAN1" [ASN_OCTET_STR]
     1.3.6.1.2.1.47.1.1.1.1.7.12 = "Sensor1" [ASN_OCTET_STR]
     output is a string !!!!
    and 
    1.3.6.1.4.1.43.45.1.10.2.6.1.1.1.1.12.8 = "65" [ASN_INTEGER]

    About last OID was told:

    h3cEntityExtTemperature OBJECT-TYPE
    DESCRIPTION : The temperature for the entity.

    But this number is very high and It is very different from the number displayed in the switch management portal.
