adding a new interface, selfIP and VIP

I've been trying to follow instructions and setup a new interface, selfip and VIP (on the selfip network) and i cant get it to work...

my attempt looks like this:

i've been following:

https://techdocs.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/tmos-routing-administration-11-6-0/2.html

https://support.f5.com/csp/article/K12149

I had the new NIC added to the BigIP VirtualMachine, then i ran

rm –f /var/db/mcpdb*

touch /service/mcpd/forceload

then restarted the box

then ran

f5-swap-eth -w

cat /etc/ethmap

the cat command showed an additional MAC address which i assume was the one that was added (hard to verify)

then i tried to map in a new interface like this:

net self /Common/SomeSelfIp {

  address x.x.x.x/24

  traffic-group /Common/traffic-group-local-only

  vlan /Common/SomeVLAN

}

net vlan /Common/SomeVLAN {

  interfaces {

    1.9 { }

  }

  tag xxx

}

however from another machcine on the x.x.x.x/24 network i cant ping this interface..

is there something else i need to do to get it come up?
