Hello Everyone,
Well i am encountering a problem where i am unable to connect through the the internet from my ACCESS layer switches which are connected to a DISTRIBUTION switch i.e Cisco 3550 , Where as all other distribution & Access layer switches connected to them are working properly on my network. Everything is running perfectly on this 3550 switch and i am able to ping the google public DNS 8.8.8.8.8 from this DISTRIBUTION and further ACCESS layer switches connected to this DISTRIBUTION shows proper connectivity as trunk ports shows green light and continuous blinking but active ports on the access layer shows AMBER and users are not been able to browse the INTERNET. Please Help me in this regard and any help would be greatly appreciated.

Hi so all other access switches can reach the internet yes just 1 effected that's linked to the 3550 ?
Can you post the logs from the access switch effected along with its show int trunk and show run if its layer 2
Can this effected switch reach other switches in the lan without issues?
Have you the same gateway set as the other access switches ?
Are these user ports DHCP are they getting an address and DNS information ?

Hi Muhammad,
An amber color indicates that the port is blocked because some error condition has been detected. These are some (though not all) reasons for a port to be indicated as amber:
