15600 Cluster r80.20

[Ds]

Hi ,

we have 15600 cluster we see switch-over that is not related to any interface down or up suddenly  

There is a strange phenomenon that we see in the cluster log 

the log from the active unit :

Jan 2 11:18:03 2020 XXX-15600-INB-FW-01 kernel: FW-1: stopping debug messages for the next 57 seconds
Jan 2 11:19:00 2020 XXX-15600-INB-FW-01 kernel: FW-1: lost 1554 debug messages
Jan 2 11:19:00 2020 XXX-15600-INB-FW-01 kernel: [fw4_0];fw_xlate_cliside_server failed
Jan 2 11:19:03 2020 XXX-15600-INB-FW-01 last message repeated 98 times

the log from the standby unit : 

Jan 2 16:18:52 2020 XXX-15600-INB-FW-02 kernel: ixgbe 0000:87:00.0: eth1-01: Fake Tx hang detected with timeout of 20 seconds

Jan 2 16:18:57 2020 XXX-15600-INB-FW-02 kernel: ixgbe 0000:87:00.0: eth1-01: -1 Spoofed packets detected

It happens all the time non-stop

thanks

Hello Ds,

sounds like a problem for TAC, please open a support case.

“fw_xlate_cliside_server failed“ means something goes wrong with NAT.

„Fake Tx hang detected“ saw this years ago with IP appliances and 10GBE interfaces, but problem is solved since R77.30 Jumbo_xxx.
