Multiple VLANs and cannot access certain ones

So I am very new to F5's and am a Systems Engineer and not heavy into IT but we need it for a project and I'm tasked with figuring it out!

 

 

Anyways, here is the issue I am having, we have 3 VLAN's. 7, 10 and 20 that all correspond to 10.1.7.x, 10.1.10.x, 10.1.20.x, respectively. Now I have gotten everything on VLAN 10 to work. I have a pool of 4 machines all with 10.x IP's and a VIP of 10.x as well and it works just dandy. But if I try to even just create a VIP in the 7 VLAN with a pool of VLAN 7 machines, I have issues and cannot even ping the VIP even though it says it is Available.

 

 

VLAN 10 is setup as follows:

 

Partition: Common

 

Tag: 10

 

Interfaces

 

Untagged: 1.2

 

The rest in Available

 

 

VLAN 7 is setup the same way, except untagged is 1.1 and the rest in available.

 

 

Now I am not really not sure if this is correct, but I feel like something in the VLAN configuration is what is hindering me. Any help would be great!

 

 

Thanks

  • But if I try to even just create a VIP in the 7 VLAN with a pool of VLAN 7 machines, I have issues and cannot even ping the VIP even though it says it is Available.can you see icmp packet to vlan 7's vip when running tcpdump on bigip?

     

     

    e.g.

     

    tcpdump -nni 0.0 host x.x.x.x and icmp

     

    x.x.x.x is vlan 7's vip
  • (tmos) run /util tcpdump -nni 0.0 host 10.1.10.45 and icmp

     

    tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

     

    listening on 0.0, link-type EN10MB (Ethernet), capture size 108 bytes

     

     

    0 packets captured

     

    0 packets received by filter

     

    0 packets dropped by kernel

    Nothing happened. Not sure if I ran that correctly, but I eventually just had to do a Ctrl C to get out of there.

    0 packets dropped by kernel it seems packet does not arrive at bigip.
