I am using the uCMDB 10.20 CP 15. I am not able to discover the topology between switch and the host.
I alraedy run the below jobs - Host Connection by SNMP job - Host Networking by SNMP job - VLANS by SNMP job - VLAN ports by SNMP job - Layer2 Topology Bridge-based by SNMP job - Layer2 Topology VLAN-based by SNMP job
I found some Layer2connection as correct that are connected to the host as i need to find
but i didn't get the host which is attched to some switches.Attached is the Screen shot which i am getting.
These host are actually the vios server of IBM and when i checked through the SNMPWALK whether the snmp is enabled or not but that was enable.
Now my question is that for finding the correct topology
1.SNMP has to be enabled to both the sides (switch and the server)
2. Which version of snmp agent is needed to discover the vios server
3. If a host is discovered by some other job then if we want to discover the topology by some other job. will it discover the topology with that job.
or there any other thing i am lacking in finding the topology.
SNMP v2c on the host side, and v3 on the switch/router side.
I opened a case with support about this, and they basically said that this has been an issue since NNMi v9.x, and the Product Manager has denied enhancement requests to fix this until this moment, which is shocking to me.
Anyways, I am in the middle of running discoveries in NNMi and uCMDB and will report back ASAP.
The key is the Layer2Connection CI, which should be discovered, if using SNMP v2c or v3.
However, given my experimentation thus far, only NNMi finds this connection, and the NNMi integration with uCMDB is currently inadequate, since it sends over all of the NNMi inventory as CI Type Node versus Switch, Router, etc.
Because of this, the uCMDB/RTSM Impact Rule for downstream suppression of events may not work.
I need to get a friend of mine on the network team to open up SNMP for a particular switch and perform discovery in uCMDB on that switch. Then, I will let you know my results.
In short, the NNMi discovery does work fine, regarding the Host <=> Switch Layer2Connection.
uCMDB results to be reported later today or tomorrow.
