Troubleshooting the BIG-IP Virtual Edition

If you have followed the setup procedures in this document, BIG-IP VE should be working correctly with the hypervisor. However, because BIG-IP VE emulates BIG-IP hardware running in a virtual environment, you might encounter some issues as you try new configurations for BIG-IP VE that are outside the scope of this setup guide or altogether not supported in BIG-IP VE with certain hypervisor environments. Use the following troubleshooting information to solve problems and learn of limitations that you might encounter with BIG-IP VE.

Virtual network interface status is wrong
The BIG-IP VE system reports the status of host-only network interfaces as UNINITIALIZED, even though the interface is functioning normally.
Auto-licensing and the default management route
If you have not defined a default route to the management port, the default interface 1.1 is used, which does not work. To prevent this from occurring, verify that you have defined a default route for the management port before attempting to activate a license.
BIG-IP licensing and User Configuration Sets
When you import a User Configuration Set (UCS) from another BIG-IP or BIG-IP VE system, the system overwrites the local license with the license contained in the UCS. To work around this issue, you can re-license the local system after importing the UCS by accessing a backup copy of the license file, located in /config/bigip.license.bak. Also, when importing a UCS, you should ensure that the host names of the two systems differ. When the host names differ, the system correctly imports only the configuration data that is common to both the originating platform and the target platform. If the host names match, the system attempts to import all of the UCS configuration data, which can cause the import process to fail.
Editing the virtual guest configuration
F5 Networks strongly recommends that you do not edit the virtual configuration of BIG-IP VE, except for the virtual network interface mappings.
SSL::sessionid iRule command
The SSL::sessionid command within an iRule returns a blank value with BIG-IP VE.
Use of SNMP OID for RMON tables
Setting the source OID for RMON alarm, event, and history tables generates an error message. This OID will be disabled in future releases.
Media speed messages in log file
When starting the BIG-IP VE system or when removing an interface from a VLAN, the system logs media-related messages to the file /var/log/ltm. You can ignore these messages.
Exiting the shell at a MOS bash prompt
When you type exit at a Maintenance Operating System (MOS) prompt, the system appears unresponsive. Use the hypervisor's reset controls, or power off and power on the BIG-IP VE virtual machine to restore functionality.
Importing a UCS from the BIG-IP Virtual Edition Trial
When you import a UCS from the BIG-IP Virtual Edition Trial, the system displays an error message. You can ignore this message.
The virtual switch clears the QoS field in 802.1q headers
A hypervisor's Layer 2 bridging device might remove quality of service (QoS) classification from packets.
