NimbostratusMultiple 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
Danny

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 
Danny_Ellis_115(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

Nothing happened. Not sure if I ran that correctly, but I eventually just had to do a Ctrl C to get out of there.- nitass0 packets captured

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