Nexus 7000 not generating log for duplicate IP Address

[vishal_nijapkar]

Hi ,
Recently I had came across 1 issue where one of the server IP  had conflicted with VIP of Nexus core switch. The blade server was physically  connected to Nexus Distribution switch which in turn connects to Nexus  core.Neither Nexus core nor distribution had generate any logs in  regards to IP conflict which ideally happens on Cisco catalyst  switches.I haven't find any document on cisco as well as on internet for  this issue . I dont know what logging need to enable on Nexus for this specific  case . There are different logging levels define for every feature like hsrp,  ip,monitor etc...We have Nexus 7k with latest release 4.2(6)  Software
BIOS: version 3.22.0
kickstart: version 4.2(6)
system: version  4.2(6)Your help is highly appreciated.
Thanks,Vishal

Hello,

Nexus react only on ip addresses that are the very same a it has configured on the routed ip interface.

For other issus within that L2 Domain, other techniques has to be used.
