Look like NIC bonding is needed?<br />
<br />
If not wrong, both nic1 &amp;&nbsp;2 have to be blank. After that, create a bond0 for both nic1 &amp;&nbsp;2. Then create ifcfg-bond0.100 &amp;&nbsp;ifcfg-bond0.102, for the respective VLANs. is that correct?

This is using SuSE Enterprise Linux 12 SP4. There are 2 NIC available on this server. These 2 NICs are connected to separate distribution switch, accordingly for the high availability. If NIC1 connection is down, so long as NIC2 connection is up, both NICs are working.<br />
<br />
On the 2 distribution switches, both these NIC ports are configure as a trunk as below,<br />
<br />
&nbsp; &nbsp; switchport mode trunk<br />
&nbsp; &nbsp; switchport trunk allowed vlan 100,102<br />
&nbsp; &nbsp; switchport trunk native vlan 1<br />
<br />
Vlan 100 is public segment, and 102 is backup segment. On the SuSE linux server, NIC1 is configured with IP for public, and NIC2 for backup. How should we configure the NIC1 and NIC2 in order to support this trunk ports from 2 distribution switches?<br />

Thanks in advance
