Two Cisco 2960X on FlexStack and need SNMP monitoring

Dear All,

Our company has installed two Cisco 2960X switches. They are linked up and configured with a FlexStack cable for Resiliency and only One IP Address is assigned to the FlexStack Group. We would like to use SNMP monitoring application (i.e. Whatsup Gold) or other SNMP monitoring tools to monitoring the Up/Down status of the two "individual physical switches". Our objective is that the SNMP monitoring apps will send alert if Any one of the 2960x switch is down (e.g. Hardware failure that cause one switch malfunction).

Is anyone know whether it is possible and kindly give me some direction.

Thank you so much for your advice in advance.

Regards
Patrick

Yes, the 2960 does support SNMP. You'll need to set a read-only and read-write SNMP string on the switch like this:

config t
snmp-server community myreadwritestring RW
snmp-server community myreadonlystring RO
end
wr mem

(replace myreadwritestring & myreadonlystring with difficult to guess strings of text)

Then configure the SNMP monitoring tool with the two SNMP strings and then scan the IP used by the switch.

Thank you for your advice. As we are using Two Cisco 2960x using FlexStack to linked together and assigned only one IP address to the combined switch.

I would like to know if only one of the Switch is down (Hardware failure or Switch off), Is SNMP still able to identify this kind of incident with one member down ?

Appreciate you advice in advance.

Monitoring tools usually do not understand that a switch stack is more than one switch. If the stack master fails, the monitoring software will only be able to communicate with the other stack member if the switch has its own network connection.
