I am facing authentication issue on ISE but meanwhile, I have noticed one more issue and I guess because of that, I have an authentication issue on ISE. I have Cisco Catalyst 3850 switch when I hit the sh mac-address-table command, it shows me same mac address twice.
Mac Address Table
-------------------------------------------
Vlan Mac Address Type Ports
---- ----------- -------- -----
377 2c44.fd2f.9471 DYNAMIC Gix/x/x
377 707c.6901.277a DYNAMIC Gix/x/x
256 707c.6901.277a STATIC Gix/x/x
Could someone have any idea on this? Why it is showing me the same mac address twice on the interface as a static and dynamic. It is a common phone and pc arrangement on the switch port.
