Can you tell me how to see the syslog?In message under etc/log, I did find logs during the disconnection occurred but thats is related to some customized application crash that is no way related to the network fluctuation.
In switch, we found that the particular port dedicated for LAN A and LAN B (LAN A + LAN B = bond 0), got up and down for 10 seconds during this period.This has happened thrice.
But there are other ports that are connected to different devices other than the LAN A and B for Linux server, shows no interruption.And here I am apprehending that the fluctuation occur in the bond 0.
But I am not clear in one thing?
Bond0 fluctuation will happen if physical Ethernet ports fluctuates or bond0 fluctuation results in fluctuation in LAN A and B shown in Switch.
We do not have more information from switch.
Can you bit give some example of commands for "netstat" or "tcpdump" utility to dump the netwrok activity log if any?
