Hello everyone,

I wonder if anyone have had a similar issue as the one I have been experiencing, I have create a Trunk port with dual link for redundancy and added as Po66 by example.
then created a sub interface with the IP 172.1.1.1/24 VLAN 66 zone: inside
But I m unable to ping the device attach to the inteface although is set as: 172.1.1.2/24 over VLAN 66
My enviroment topology links:
FRP - Spine Switch -> Leaf switch -> device (status: drop)
as reference I am connected as work station -> Leaf Switch ->  Spine Switch -> Management servers -> VM -> Virtual FMC (status: OK)
I did tried packet tracer with a concerning result:

VLAN66(vrfid:0)

Yes random IP

Later when you config any ACP use IP from ACP to check it.

Here as you mention there is no any ACP use any IP

But always remember in packet tracer dont use IP of any interface of FW

sorry the link is up but no traffic flowing

How you run packet tracer?

What is IP you use abd what is IP of interface 

MHM

I have seclected the applicance then
Protocol: TCP
Source Type: ipv4 172.1.1.1
source port: http
inline tag: Empty

Eggress interface: VLAN66
VLAN: (grayout)
Destination type: ipv4 172.1.1.2
Destination port: http

Allow the simulated packet to trans... etc 

If you use interface IP in packet tracer then you will get this result 

Try do packet tracer again and dont use IP of any FPR interface 

MHM

Thank you MHM,

But what you mean? the only options are IPv4 and 6 as FQND? jusy use a random IP?
