This section describes how to verify and troubleshoot issues withthe IP address and the default gateway of a VM.
To verify the IP address and default gateway on a VM:
Log in to the VM in question.
Run the following command:
ip a
Example of system response:

If Ethernet does not have an IP address, run the following command:
dhclient eth1
If Ethernet has an IP address with the
/32
mask:- Restart the VM.
- Verify ifmap-server.
If the interface is down, run the following command:
ifcongfig eth1 up
Display the default gateway:
route -n
