finds nexus 7010 for each vlan that it is in

[ Edited ]

hey

 

we have some cisco nexus 7010 that is being discover for each ip segment that is in our auto discovering(I can see all inter face on each of them but only one ip segment) we are using some vrf lite but 10.201.73.3, 10.201.84.3 and 10.201.80.3 is in the same vrf so I don't think that is the issue for this behavior

I have also tried to delete them and they just pop up like this again

 

is there some issues that nnm can't snmp correctly to a nexus 7010?

nexus 7000 issue vrf.png

nnmdiscotech.ovpl -summary

Management IP address=10.6.29.12 has 0 duplicate nodes.

Re: finds nexus 7010 for each vlan we auto discover

Is your 7010  logically partitioned into vswitches ?

Have a nice day :)

Re: finds nexus 7010 for each vlan we auto discover

Nexus 7xxx  Virtual Device Context (VDC) is not fully supported in NNMi. Virtual devices (VDCs) configured with separate Management IP and SNMP access are discovered and managed as independent Nodes in NNMi. However, VDCs that share a common Management IP but separate SNMP Content (v1/v2 community or v3context) cannot be managed in NNMi. Further, the association of VDCs to the hosting (physical) Nexus switch is not depicted in NNMi.
Older NX-OS versions have limited SNMP MIB support that impairs associated NNMi support. NX-OS 5.0(2) or later required for proper discovery of Layer 2 connectivity. Nexus 5000 NX-OS 5.0(3)N2(1) required for proper Link Aggregation support involving Nexus FEX modules. See http://sg-pro-ovweb.austin.hp.com/nnm/NNM9.20/devicematrix.htm   In case NNMi is discovering a new instance of the same node each day (duplicated nodes) when all the interfaces of the node are excluded from discovery, then install patch 3.


Hope this helps.

Re: finds nexus 7010 for each vlan we auto discover

Might be the version of NX-OS you're running,  its still pretty primative , but getting better.  4.X was a hot mess.

 

 

We've got about 150  7010's runing this version and dont have any issues mapping.

Re: finds nexus 7010 for each vlan we auto discover

might be that we has some snmp issue with the nexus 5000 were the snmp service crash on them so if the nexus 7000 have som snmp issues it will not be that big of a suprise, the sad thing is that they are in pretty most 24 hours use

 

thx for info i hope it helps:)

Re: finds nexus 7010 for each vlan we auto discover

Nexus 5020's are even worse than the 7010's.   The software is late beta quality at best.

Have a nice day :)
