SNMP discovery

[hemanth029]

we want to create discovery schedule setup in DEV system that ONLY uses SNMP. This is possible in service now by setting the capabilities (of the schedule or MID server, I can't recall which). This we would run against the   IP space, block by block and see if we find any additional Cisco devices to add to the discovery schedule in production.

So need your help how to do achieve this. if yes then please let me steps which i need to follow.

Hi Hemanth,

Yes, You can achieve it by creating Discovery Behaviour for SNMP only. To Create a Discovery behavior

Still having no luck with this. What we want to do is:

• Run SNMP-only discovery on the entire IP space to find routers and printers
• Run all but SNMP discovery on specific ranges where we expect to find servers

There is something I am missing from these instructions because all probes are still running.

If I create a discovery schedule using a specific MID server and then a behaviour for SNMP only, I would expect only SNMP probes to run. What am I missing?

• Behavior:
  • Name: SNMP only
  • Application: global
  • Functionality
    • Phase 1
    • Functionality Definition: SNMP only
    • MID Servers: SNMP_MID
    • Application: Global
    • Match criteria: All
      • Criteria mid_server equals SNMP_MID
• Schedule
  • Behavior: SNMP only
  • MID Server: SNMP_MID

? What am I missing?

To confirm, your schedule 'Mid Server Selection Method' is 'Use Behavior', correct?

If you don't want to use behaviors, you can configure port probes and have SNMP with a higher priority than SSH. If the CI is a router\switch then WMI scan will be ignored and SNMP will kick in.
