<div dir="ltr">Afternoon, <div><br></div><div>I have a very strange issue. I have a FreeNAS from iX Systems that has two nic. The first is used for productions (igb0) and the second(igb1) is used for backup. Every morning between 3am to 4am, the backup network nic (igb1) traffic appears to have stop. Because no data is being transfer. If I do the following </div>
<div><br></div><div>ifconfig igb1 down</div><div>sleep 5</div><div>ifconfig igb1 up </div><div><br></div><div>Traffic starts again. </div><div><br></div><div>There a bit of details about my network </div><div><br></div>
<div>
production <a href="http://192.168.0.0/24" target="_blank">192.168.0.0/24</a> </div><div>backup <a href="http://10.1.0.0/24" target="_blank">192.168.1.0/24</a></div><div><br></div><div>Both networking use the following as the default gateway 192.168.0.254. </div>
<div><br></div><div>No Vlans. <br clear="all"><div><br></div><div>Each Network has it own switch. </div><div><br></div><div>Here is where I need help. I been working with FreeNAS, they think my problem is as follows. </div>
<div><br></div><div>1) I have a switch that is going bad. </div><div>2) That my switches might be bridged. I assume that means I have a cable between each switches. </div><div><br></div><div>There reason that they thing it's either bridge or bad. Because of the following that we are setting on the FreeNAS. </div>
<div><br></div><div>We are seeing in the logs are arp changes for lets ip 192.168.0.2 on mac address xx:xx:xx:xx:xx (which is eth0) because change to yy:yy:yy:yy:yy with is mac address 192.168.1.2 ( eth 1) </div><div><br>
</div><div>I am lost, because I am not sure how to fix it this. How can I see if my switcher are bridge. What would be the best practice. </div><div><br></div><div>If I had a bad switch, should I try updating the firmware?</div>
