Hi,
We have cisco Nexus9000 C93180YC-EX
Version : NXOS: version 9.3(7)
We have 15 FEXes connected to it, and around 300 servers connected to it total.
All of the boards are working with DHCP, and booting the OS from PXE.
We are working in a QA and few other test's environment, which means that dozen of servers are rebooting few times in a day. sometimes it's few servers in the same time.
We've noticed that in the last 2 months, when the servers rebooting, few of the servers [randomly] are not getting a link, and only after additional reboot, the link gets up, and it's getting DHCP and booting from PXE.
We now noticed that the CPU is very high during the large reboots scales.
Can it be that we are getting the Nexus into state that it just can't work properly in this workloads ?
Do you have any way to check it ? some commands etc. ?
Thanks in advance
