LTM VE interfaces have no IP address

I've installed the lab license on the F5 VE appliance (created in ESXi 5.5 and Workstation 9) and can run the setup utility to assign a management IP address and assign Int/Ext vlans and interfaces. When I go to the command line and run an ifconfig, the interfaces have no IP assigned and I can't get any Int/Ext traffic flow. Am I doing something wrong or is it not setup correctly?

    Hello lboogie25,

     

    Assuming the hypervisor environment is configured properly (vSwitches and interfaces), you can configure the BIG-IPs VLANs, interfaces and IPs using tmsh commands.

     

    (Change the IPs for your environment)

     

    [root@localhost:Active:Standalone] config tmsh

     

    root@(localhost)(cfg-sync Standalone)(Active)(/Common)(tmos)

     

    (tmos)create net vlan internal interfaces add { 1.1 }

     

    (tmos)create net vlan external interfaces add { 1.2 }

     

    (tmos)create net self 10.10.20.6/24 allow-service all vlan internal

     

    (tmos)create net self 10.10.10.10/24 allow-service all vlan external

     

    (tmos)save sys config

     

    (tmos)quit

     

    Then from the CLI, you should be able to see the vlans ‘internal’ and ‘external’ with assigned IPs and associated to the interfaces.

     

    [root@localhost:Active:Standalone] config ifconfig | egrep 'Ethernet|inet'

     

    eth1 Link encap:Ethernet HWaddr 00:0C:29:72:3B:99 inet6 addr: fe80::20c:29ff:fe72:3b99/64 Scope:Link

     

    internal Link encap:Ethernet HWaddr 00:0C:29:72:3B:99 inet addr:10.10.10.10 Bcast:10.10.10.255 Mask:255.255.255.0

     

    eth2 Link encap:Ethernet HWaddr 00:0C:29:72:3B:A3 inet6 addr: fe80::20c:29ff:fe72:3ba3/64 Scope:Link

     

    external Link encap:Ethernet HWaddr 00:0C:29:72:3B:A3 inet addr:10.10.20.10 Bcast:10.10.20.255 Mask:255.255.255.0

     

    You can also check the configuration files to make sure things are correct. In the example above ‘allow-service all’ was set for the self IPs, search the configuration file /config/bigip_base.conf for 'net interface' and 'net self'
