Mapping of Server's network interface to switch port in related CI's in UCMDB

Hi experts,

We have

1) UCMDB 10.22 with UD agent,
2) OMi 10.10
3) NNMi 10.01.
4) OML 9.x
5) Sitescope 11.31

UCMDB is integrated with OMi (CMS-RTSM), UCMDB is also integrated with NNMi, OML & Sitescope are integrated with OMi for events.

we have one application hosted on some servers and network switch in our enviroment , switch and all server are discovered by UD agents, and also being monitored by NNMi & OML respectively

we want to have view/model where every server’s network card to switch port connectivity is automatically identified and visible as part of topology. This topology will help in event correlation for example when network port or network switch becomes faulty due to which server & application is unavailable multiple events will be fired here TBEC will map switch/port as cause events and application down as symptom event.

Logic is when all CI’s (switch/server) are present in UCMDB it should be able to build topology view automatically, as it knows which port is physically connected to which switch based on this it should be also reflected in related CI’s and topology.

Problem we are facing here is UCMDB is not able to do reconciliation of server switch port with network switch port and build topology. can expert guide how to solve this issue?

Re: Mapping of Server's network interface to switch port in related CI's in UCMDB

Sounds like you are looking for the data link layer, the Layer 2 connection
Obtain an SNMP community string with the appropriate permissions (check the guides) and a discovery credential for your servers with the appropriate permissions. Fully discover both switch and servers first then run the Layer 2 discovery as stated in the guides.

What you should get get out of Layer 2 discovery is a Layer 2 CI with membership relationships to 2 Interfaces with one Interface with a composition relationship to a server and the other Interface with a composition relationship to a switch.

You can make this easier to consume in reports by using a compound relationship with using the steps I discussed above.

Re: Mapping of Server's network interface to switch port in related CI's in UCMDB

thanks ray

appriciate your suggestion 

we are aware this can be achived by enabling SNMP discovery on both (server side & switch side) . its even possible when we add servers & switches in NNMi with snmp monitoring enabled (it gives end to end layer 2 topology).

challange is security team objected enabling snmp on servers,  we already have UD and OM agents/ for inventory and monitoring.  i'm exploring if we can utilise capability of these server agents (spacially UD agent) to help UCMDB reconcile and build layer 2 end to end topology without enabling SNMP on servers.

best regards

Did anyone accomplish this? We're having the same issue where people are requesting Layer 2 info but are unwilling to enable SNMP.  Can the UD agent and/or nnmi integration not provide this info?

Re: Mapping of Server's network interface to switch port in related CI's in UCMDB

Hi Rey,

 

We have already discovered the switches using host connection by snmp and servers are using by host connection by shell and run the layer 2 discovery still we are not able to discover the layer 2 connection between server and switches. I came through some document and found CDP-LLDP should be enable on both sides of the wire so how we can enable the CDP-LLDP on server side. Did you discover the layer 2 connection details in your envrionment.? How you enable the CDP-LLDP on server side? Please suggedst.

Regards

Rohit
