Hi Everyone,
I would greatly appreciate your help, the log in a cisco Nexus9000 C9336C-FX2 Chassis is showing high temperature in three ports Ethernet1/34, Ethernet1/35, Ethernet1/36:

NXOS: version 9.3(9)
these ports part of vPC Peer Link KeepAlive (1/34) and vPC Peer-Link L2 (1/35, 1/36)
the warning of high temperature is only in the main switch , in the other side I don't have the problems.
I've read some cisco articles and speaks about the bug version (5.2(1)N1(4)), but is not my case,

how can I know what is the main problem?
