ASA 5512X and Aruba Switch 1930 L2

[Manojy]

Dear Team,

We recently introduced the IPPhone Grandstream to our organization. I created a physical interface on the ASA5512x with an IP address for the phones. The data and voice are on different physical interfaces on ASA, with data on Interface ge0/1 and voice on ge0/2. There are no sub interfaces or VLANs inside ASA. The data is on 192.168.0.0 and the IPPhone is on 192.168.70.0. Both data and voice are accessible both ways.The data and voice are connected on the same Aruba Instant 1930. I created VLAN ID 2 for voice on the Aruba switch 1930. I would like to know if I create a trunk port on Aruba switch port 46 , which is directly connected to the physical interface of ASA Ge0/2 is it workable will aruba consider it as Trunk. Can you please help and assist me with this?

Thankyou

Yes, you are right. However, I have different switches and need to apply a trunk between Aruba switch and five Linksys switches. All switches are L2.

So the ASA has two interfaces directly connected to the aruba switch that has two access ports upstream to the ASA in vlan 1 and vlan 2,

Then downstream from the Aruba, you need to have trunks interconnects to the various other L2 switches allowing vlan1/2 to traverse these trunks and have vlan 2 created on these other switches.....Thats it be tbh you should have reachability to either host in either subnet via the ASA as long that is the ASA as already stated by @MHM Cisco World  has same-security-traffic permit inter-interface" applied to allow traffic communication to traverse between the same level interfaces.
