Hi.. I would like to monitor when a switch x440-48t in a stack becomes offline.. (power down) with snmp..
I was trying to use OID ( extremeStackMemberOperStatus126.96.36.199.4.1.19188.8.131.52.1.3) with my NMS.. i actually did receive a value of '1' when the switch is on correct operation mode, but when i powered off, i did not receive any value... wich was my trigger if the value changed to '2' (down)..
Name: extremeStackMemberStatusChanged OID: 184.108.40.206.4.1.19220.127.116.11.0.2 Description: The extremeStackMemberStatusChanged notification is generated when the operational status of the stack member changes
Note: You have to configure the switch and enable "Zabbix NMS" as the SNMP trap receiver. You can confirm the CLI using the article below:
I'm using SNMP polling, i want to receive an alarm if the switch shut down (in a stack).. , that's why i was using (reading) snmp variables.. wich return a value and with my NMS i can read and make an alarm based on the value on a specific variable.
Based on OID (MIB) i can use the following on this link
So i was trying to use this one:
wich returned a value of '1'... but when i power off the switch, no value returned.. so my alarm did not apply (cause the last value was still '1', i put the alarm to trigger when the value '1' changed to anything else; when i powered on the switch, i got again the value of '1'. so that did not work,
I have switches not in a stack monitored by IP address (ping reply) with no problem, but in a stack theres only one IP address for the whole stack, wich the alarm works but all of the switches must be turn off.
I'm using Zabbix as my NMS..
SNMP timeout... that would be another variable to check for..?
