Hello,

Some equipments Nexus 5596 from a customer have reinitiated and it seems to have been provoked by an OSPF problem although I am not sure.

The logs from the equipment show:

I wanted to know if you know something about a problem with OSPF in next version:

  cisco Nexus5596 Chassis ("O2 48X10GE/Modular Supervisor")
  Intel(R) Xeon(R) CPU         with 8263880 kB of memory.
   bootflash:    2007040 kB

Kernel uptime is 0 day(s), 2 hour(s), 25 minute(s), 35 second(s)

System version: 5.1(3)N1(1a)

Thank you very much.

• OSPF logs say that your switch is fully adjacent with 180.101.250.26 and .29, this means normal operation.
• Bi-directional communication has been established between the Nexus and 180.101.250.17 and .28. They are in the middle of the OSPF neighboring process.
• Some interfaces are initializing, and Po111 and 112 have no member ports (the channel-group <111|112> command hasn't been issued on any physical interfaces).

More information about OSPF neighbor states can be found here.

Hello,

Thank you very much a_dosztal. As you have said, this is normal behaviour and anything about this log should have provoked the reset of the equipment. I have looked the status of the modules and I have seen a power supply is failed, maybe this has been the origin of the problem although this shouldn't be a problem. There are redundant power supplies.

Well, thank you very much!!!! Best regards. And thank you for being so quick answering me.
