Issue/Introduction

3 NICs during provisioning (VM Team) has configured ssg_eth0 with 11.191.xx.xx under 11.xx.xx.xx/27.  -  working fine, able to do putty

ssg_eth1 and ssg_eth2 are configured .

ssg_eth1 is working - xx.xx.xx.xx under xx.xx.xx.xx/28

ssg_eth2 is not working -xx.xx.xx.xx under xx.xx.xx.xx/28

Tried

Swap the NIC3 and NIC4 which broke the ssg_eth0 so we reverted.

Added a static route for xx.xx.xx.xx/32 which did not work.

Environment

Resolution

In the /etc/iftab, the names of the ethernets against the MAC are different to the altnames/NIC adaptor. that is why the issue occurred.

When the MACs were mapped to the correct names it was okay.
