Cisco 5508 port 6 directly connected to ASA5515x Inside sub-int, same subnet, do not see eachother

[Steve Coady]

Hello

Can someone explain to me how a gig switchport on a Cisco 5508 controller is different than an Gi0/0 interface on an ASA5515x?

Both interfaces are on same vlan.

Both interfaces show up/up

    Cables have been swapped.

    Ports have been changed.

    Arp table does not see subnet.

I have had TAC check into this and the suggestions they advise are things I have already implemented with no change.

Please review and advise.
