    Topology question ...

    kvm@regionsjaelland.dk

      Hi All

      I have now played arround with the new topology function, and is the following true:

      • It is only nodes that are found by Network sonar, that will be scaned for topology information ??
      • Nodes that have been in NPM for many years and not discovered by network sonar, has to be deleted and the found by network sonar, for then to be scaned for the topology information ??

      I hope not that it is true ... I have 450+ switches in NPM .... not found by network sonar.

      best regs

          they only need to be accessible via snmp basically...

          you can then enter each of those IPs to the network discovery...

          to make it simple, there is a video tutorial where if you follow it step by step it will work!

            You don't need to delete and re-add them via sonar.  Just take the existing list of items you are managing and create a new sonar profile and choose bulk upload and copy and paste that list into there and run the discovery.  Then just choose one of the devices to re-import and it will update the topology for those.

                Brandon,

                I  have followed the Sonar steps up to the point of import.  I've created and pasted the list of all our Cisco devices currently monitored by NPM into a Network Sonar discovery job and run the initial discovery.  I've saved the discovery results at this point and am ready to re-import almost 1000 nodes.  I would like to get clarification on "Then just choose one of the devices to re-import and it will update the topology for those.".   Okay, now I choose a particular node from the discovered list to re-import.  Will only the topology data for the ONE device be imported or will topology data for ALL devices/interfaces be imported?

                Also, do we have to import all Interface Types?  For example, on switches/MLSs, with NPM we only monitor the ethernet uplink and server ports, not the access ports.  In our network, there will be thousands (35000+) of ethernet interfaces found during the sonar discovery.  The discovery process does not provide the granularity to be able to drill into each device and select the specific ethernet interfaces to import (it would be great to have the ability to do this).  Do we have to import all ethernet interfaces to gain the topology data then turn around and manually delete all the undesired interfaces?
