We have SNMP enabled on global level of the extreme switch, but not on the port level. We are planning to enable it on the port level. So want to check, when the monitoring tool will send the snmp trap (preodically) to check the condition of the ports, so that request will be send to switch and in turn switch will parse all the ports and come up with the result and dump to the montoring tool, or the monitoring tool itself goes to each port and check the status.

Nitish,

The SNMP trap for port-up-down transitions will need to be enabled on the switch. This can be done on all ports or selected ports. This will send a trap to the transceiver whether the port state changes. The command is as follows:

enable snmp traps port-up-down ports[port_list| all]


You can also perform an SNMP GET on the following OID for the port operational status (ifOperStatus):

.1.3.6.1.2.1.2.2.1.8

Collection of the ports operational status at regular intervals may be dependent on the functionality of the NMS being used. The following is an example of a FlexView configured in NetSight that will poll frequently on the port interface and operational status:

 

Let us know if this helps.

Yes It was very helpful. Thanks for that.

I just want to confirm again, NMS i am using is Solarwinfd. So its totally dependent on the solarwind to fetch the state of every snmp enabled port after a fixed interval to know the port state, its not by the switch.

Yes, that is correct. The switch will send a trap whenever the port status changes. An NMS can be configured to poll at set intervals. I believe with Solarwinds it is the Universal Device Poller feature that can poll OIDs frequently.
