Second NIC for Monitoring

In a current project, it was necessary to connect the vSphere Replication appliance to a second monitoring network as the monitoring software was unable to reach into the replication network for network/firewall reasons. Configuring this is quite easy knowing what to do:

1. Edit the vSphere Replication VM and add another vmxnet3 NIC to it (Can be done while the VM is running).
2. Open a console to the vSphere Replication appliance.
3. Hit “Login” and authenticate with “root” and your password.
4. Go to /etc/sysconfig/networking and copy the ifcfg-eth0 file to ifcfg-eth1 in the same directory
5. Edit ifcfg-eth1 and change any value referring to eth0 to the corresponding value of eth1.
6. Go to /etc/sysconfig/network and create a symlink to the previously created ifcfg-eth1 file.
7. Enable eth1.

$ ln -s /etc/sysconfig/networking/ifcfg-eth1 ifcfg-eth1
$ ifup eth1

Done! This probably applied to all other VMware appliances, too, but no guarantee
