[athaullah_nj]

Hi

i have an known below mentioned  issue in my network. we have nexus 9k is our core and we have all SVI in it.

https://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/8021x/116529-problemsolution-product-00.html

swith model : N9K-C9508

OS :  NXOS: version 7.0(3)I7(6)

Can any share the command to configure IP device tracking in nexus environment and particularly equal  nexus command for

"ip device tracking probe use-svi" ?

Thank you.

Hello,

the command does not seem to be available on the N9K platform. On the N7K it works, not sure why they removed it...

I do not believe you have that feature in Nexus as per i know, is the Duplicate IP on SVI or End device ?

Thank you for your response.

The issue is with  end point  (VM server) .it is getting APIPA ip after restart.

Most DC Environemtn the IP pre-assigned to device, but if you lookling for DHCP for the VM, you need to give more information ?

Do you have IP helper oin SVI ? is this vPC ?  - give more information about environment. any device working  ? or only this device having issue ?

[athaullah_nj]

Yes you are correct.

We have pre assigned IP in servers.we don't want DHCP for this SVI. this issue is occurring only with vm server  some time only and not all the  time we restart.

yes we have ip helper on this SVI and i removed the IP helper command from SVI now.

yes this servers are working through vPC.

Thank you.

I do not believe this is nexus side issue for now as per the explanation, this is more VM or Windows Server side. (seen some time back on Windows 2012R2 servers, the subnet changes automatically, we need to manually put back the settings.)
