We have 8.1.2 Windows Master and 3.1.2 5240 Appliance. Appliance with L config. Until this time we were using eth1(1g). We plug FC(eth7 10g) etherhet card and assing IP on it.
eth1 192.168.1.73/24 GW:192.168.1.254
eth7 12126.96.36.199/24 without gateway.
When we unplug eth1 physically all communication lost except IPMI. Then we find out Linux does not support same IP block.
So tried add gateway to eth7 and unconfigure eth1. When we done this Appliance acted weird. Didn't take any commands. So we undone everything.
What is the recommended method to change backup nic to another nic?
There is no bonding in our config.
