Is the device a CDP neighbor with other devices in your connected topology?

It needs to be for topology to know to show the devices as connected. You cannot override what the discovery process determines the connections to be.

  Hi         

Yes CDP Neighbor , but shown lonly without connection to neighbor

  Thanks

When looking at the devices from one another and using "show cdp neighbor detail" do they each show a management IP address that matches how they are known to LMS?

Hi Marvin

2)what is ur recomendation in this regard

3)how LMS works with SNMP

Hi Marvin

most of them are different from where they known from LMS

thanks

Can you ensure that cdp run is enabled on all devices? Also on the uplink interfaces ensure that cdp enable is "enabled"

Also run a DCR verification and see if you get any errors.

Hi

How to run DCR Verifications?

thanks

Ibrahim,

Please refer to page 8 of the LMS 4.1 (not just) for Dummies document, excerpted here:

Validate the device credentials

1. Go to Inventory > Job Browsers > Device Credentials Verification

2. Click Create

3. Check the “All Devices” box

4. Check the “SNMP Read Community String” and “SNMP Read Write Community String” boxes or the SNMPv3 box.

5. Check the “Telnet/SSH” and “Telnet/SSH Enable Mode User Name and Password” boxes.

6. Uncheck the “Report type” box.

7. Enter a Job Description and submit.

8. Refresh the page until the job finishes.

9. Click on the job id.

10. All the devices should be listed as “Successful Devices”.

This procedure is also covered in the product documentation here.

Thanks Marvin
