vCMP guest 11.4 cannot add trunk (created on host) to VLAN

I'm wondering if anyone can assist. As I am provisioning a new pair of 5200v's and have setup the hosts following the guide.

 

  • I created my vlans, trunks, and associated the trunk to the vlans on the host.

     

  • I created my vCMP guest, associated the proper vlans to the guest in the deployment menu (bridged mgt)

     

  • I accessed the new guest and logged in and licensed all the modules and started configuration using the guided deployment wizard at startup.

     

  • Vlans are stating no interface is attached when assigning self ip's in wizard

     

  • Completed wizard and manually added the trunk to the vlan but when adding the trunk to the "tagged" box it states: 01020036:3: The requested vlan_member (/Common/ext_vlan f5-int-ext-pro_trunk) was not found.

     

  • Checked my bigip_base.conf and everything looks the same as running systems we have, but it just wont allow the association of the trunk to the vlan.

     

Other odd issue Attempting to ping my mgt gateway works on vCMP guest, but if I try to ping a different VLAN on my switch it tries to take my external interface instead of using my mgt gateway (which my vCMP host will take) and the interfaces are bridged.

 

I want to know if I have a misconfiguration on my end or if this is a bug. If anyone has some vCMP familiarity and could assist it would be greatly appreciated. ***nb: I already have a case with F5 support but wanted to resolve this as quickly as possible due to time constraints.

 

Thanks

  • do you have interfaces in the vCMP guest? something like 1 and 2 above you physical ones?
  • So interfaces show Status /Name / MAC Address / Media Speed / VLAN Count / Trunk UP 0.3 2:1:23:45:0:2 10000 4 UP 0.4 2:1:23:45:0:3 10000 4 UP 0.5 2:1:23:45:0:4 10000 4 UP 0.6 2:1:23:45:0:5 10000 4 Also my trunk's show the trunk (f5-int-ext-pro_trunk) with interfaces 2.1 and 2.2 as members (which come from the host), the available ones are 0.3, 0.4, 0.5, 0.6
  • This issue has been resolved. We found that when you create your vCMP guest a default route is created to the external vlan. Our external vlan has no access to internal network. We created the 3 private range static routes and this allowed any pings or traceroutes to go internally and resolve. It turns out the GUI Setup Wizard will state VLAN has no interface configured warning, this should really be updated to state that if this is a vCMP guest, they do not require an interface associated with VLAN's as the Host will be responsible for this. It also is not stated in the vCMP configuration guides (or if it is not very clearly) Thanks for your help!

    I think that's dependent on how you perform the configuration. if you exit the wizzard steps at the first opportunity, you get to configure all that as you want it rather than the internal/external vlan assumptions being made
