Good morning, I am upgrading the switch model IE2000 from version 15.2(4)EA5 to 15. 2(7)E2 version Compliance according to cisco, doing this I am noticing that from the Zabbix monitoring systems when snmp query is performed on the status of the power supplies of the equipment, which in most of these devices only have connected the PSU A and PSU B is not connected / installed on the equipment, the snmp response value goes from a code 5 (notPresent) to a code 6 (notFunctioning). This didn´t happen with the previous version of IOS.
Examples of unupgraded and upgraded equipment and the snmp response it gives:
ESCAR1SWPACR0308 (10.85.236.141) version: 15.2(4)EA5 without upgrade, the status of PSU B when queried to the switch via SNMP from any Zabbix machine is as follows:
snmpget -v3 -credentialsSNMPv3 -On 10.85.236.141 1.3.6.1.4.1.1.9.9.13.1.5.1.3.3.1005
.1.3.6.1.1.4.1.9.9.13.1.5.1.1.3.1005 = INTEGER: 5 (notPresent)
ESMZX1SWPACR0401 (10.116.10.41) version: 15.2(7)E2 updated from 15.2(4)EA5, after update, we check after asking the equipment, that the state of PSU B changes value:
snmpget -v3 -credentialsSNMPv3 -On 10.116.10.41 1.3.6.1.4.1.1.9.9.13.1.5.1.1.3.1005
.1.3.6.1.1.4.1.9.9.13.1.5.1.1.3.1005 = INTEGER: 6 (notFunctioning)
The SNMP response value changes from code 5 to code 6.
Zabbix treats value 6 as a problem, since for the same device the PSU is in an error state (NOT FUNCTIONING).
