Virtual IONs sending the IP address instead of the hostname in the HOSTNAME field of syslog messages.

• An ION device that has controller port will send the controller IP address. 
• Example: Virtual ION - ION 7108v has a controller port and will send the IP address. 
• Physical ION devices that do not have a controller port always sends the hostname instead of the IP address.
• Example:. Physical ION devices 1200-S, 3200 and 9200 have not controller ports and will send the hostname.
• Refer to the logs below:
• Virtual IONS show the IP address in the sylog message HOSTNAME field. For example we see the IP address 10.100.102.1 in the HOSTNAME field.

• For the physical IONS we see that the syslog message has the device hostname in the HOSTNAME field. In the example below we see the hostname 9200-ION-1.

• Virtual ION 7108v
