when i configure the DHCP with specific MAC address…

Peace 4 all,

When i configure DHCP whith specific MAC address every thing works fine with me till i connect my labtob through the switch it didnt assign the IP address !
Note that i checked my local area connection and i obtained the IP address automatically but still not working !

Switch#show ip dhcp binding
IP address Client-ID/ Lease expiration Type
Hardware address
10.103.0.1 0011.25b2.8a28 Infinite Manual

the IP address was assign here, but when i connect my Labtob for test there is no connectivity!
