Cisco Prime LMS 4.2 unresponsive alarms

[cwallin]

Hello LMS community, I am a bit confused about how LMS 4.2 monitors interfaces that is shutdown and hope that you can share you experince with this problem.

I have a router with a vlan interface configured with an IP but shutdown.

Even though LMS detects the interface as shutdown, it report it as a an “Unresponsive error” in Fault manager.

This is a result of LMS trying to poll that IP interface, and since it is shutdown it cant reach it.

Is this really normal behavior? Are you seeing the same thing on your installations?

Would the logical thing be for LMS to ignore polling of any interface that is shutdown?

Router output:

Vlan4059               10.130.94.38    YES NVRAM  administratively down down

Alarms in Fault Manager (as you can see LMS have detected the interface as admin status down):

Hi ,

Unresponsive

Description: Device does not respond to ICMP or SNMP requests. Probable causes are: •On a system: ICMP Ping requests and SNMP queries to the device timeout received no response. •On an SNMP Agent: Device ICMP ping requests are successful, but SNMP requests time out with no response. A system might also be reported as Unresponsive if the only link (for example, an interface) to the system goes down.

As the device is still managed in DFM though the Interface is down , you will get these alarms , however if you do want alerts for a specific interface or module then you can SUSPEND \ Resume it from:

Monitor > Fault Settings > Setup > Fault Device Details
