DHCP MAC binding issue

[Mahmoud Marie]

Hello 

I created DHCP on Cisco C9200 switch and it working fine but when I tried to configure MAC binding the Interface become "Unknown" as below snapshot, why it not assigned to VLAN as the Automatic?

The configuration that I used for MAC binding:

ip dhcp pool Printer
host 10.11.11.14 255.255.255.0
client-identifier 0178.6024.2904.a9

Appreciate your help

Thanks

Can you post-show the version of the device, also is the user connected and get the IP address correct?

I am thinking because there is no expiry time on that, ?

post complete config of DHCP config.
