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?

WAKE(8) BSD System Manager's Manual WAKE(8)
NAME
wake -- send Wake on LAN frames to hosts on a local Ethernet network
SYNOPSIS
wake [interface] lladdr [lladdr ...]
DESCRIPTION
The wake program is used to send Wake on LAN (WoL) frames over a local Ethernet network to one or more hosts using their link layer (hard-
ware) addresses. WoL functionality is generally enabled in a machine's BIOS and can be used to power on machines from a remote system with-
out having physical access to them.
interface is an Ethernet interface of the local machine and is used to send the Wake on LAN frames over it. If there is only one Ethernet
device available that is up and running, then the interface argument can be omitted. lladdr is the link layer address of the remote machine.
This can be specified as the actual hardware address (six hexadecimal numbers separated by colons) or as a hostname entry in /etc/ethers.
wake accepts multiple lladdr addresses. Link layer addresses can be determined and set using ifconfig(8).
FILES
/etc/ethers Ethernet host name data base.
SEE ALSO
ethers(5), ifconfig(8)
