Notice that the UDP discovery packet has been sent, the State = 3 "Selecting", and the final line "Timed out selecting state". What's happening is a DHCP Server is not responding probably due to a connectivity issue. "Selecting" to me is not the correct verb for what is happening here, how about "waiting for reply", or "No Response"? The causes can be:
1) A Layer 1 connectivity problem: Incorrect speed, duplex, cabling.
2) An ACL is blocking DHCP from the ISP. To fix it ASAP you need the following in an ACL
ip access-list extended 101
permit udp any any eq bootpc
Then on your ISP facing Int
ip access-group 101 in
3) Some weirdness on your ISP side. I saw posts here talking about they had to register the hostname or client-id with specific providers. You may want to check with them.
My ISP AT&T using a NetBridge device containing a USB cell modem attached to a FastEthernet port, the weirdness is sometimes it takes 3 minutes and 30 seconds to obtain an IP, sometimes it comes back within a few seconds. So weirdness exists and is likely specific to your hardward and ISP.
Other useful commands in troubleshooting:
sho dhcp lease
release dhcp f0/1
renew dhcp f0/1
The bottom line is if debugging shows State = 3 "Selecting", and "Timed out selecting state". You are not connecting or the DHCP Server is not responding. Enjoy!
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
