Hmm... on your DHCP server, try setting the "default router" IP for each pool to be the VLAN ID on the switch.

scope 172.16.0.0 /24
router 172.16.0.1

scope 10.20.8.0 /22
router 10.20.8.1

I think the DHCP replies aren't going back where they should. I've never done this without a router doing all the DHCP, but it does work and i've done it many times. Your config looks spot on for the switch.

Hi

Instructions
telnet to the IP address of the Cisco switch
Enter the telnet access password for the Cisco swict when requested, and then the "Enter" key.
Type "enable" at the command prompt, and then the "Enter" key.
Enter the Privileged Exec password when requested at the command prompt, and then the "Enter" key. Then enter "configuration terminal" at the command prompt, and then the "Enter" key.
Type "interface fastethernet0/1," replacing the "fastethernet0/1" with the name of an interface in which you wish to enable PoE, and then the "Enter" key. Then, while in interface configuration mode, type "power inline auto" and then the "Enter" key. Repeat this step for each interface in which PoE is required.
Type "end" at the command prompt and then the "Enter" key, copy running-config
Below is some commands to run, I don't have any power on the interface but this will show you if this is working...

Run this command to see the interface is up.....

You can only reset password this way:
1.
Attach a terminal or PC with terminal emulation (for example, Hyper Terminal) to the console port of the switch.
Use the following terminal settings:
  • Bits per second (baud): 9600
  • Data bits: 8
  • Parity: None
  • Stop bits: 1
  • Flow Control: Xon/Xoff
2.Unplug the power cable.
3. Hold down the mode button located on the left side of the front panel, while you reconnect the power cable to the switch
4. Release the Mode button when the SYST LED blinks amber and then turns solid green. When you release the Mode button, the SYST LED blinks green.
5. switch: flash_init
6. switch: load_helper
7. switch: dir flash:
8. switch: rename flash:config.text flash:config.old
Rename config.text to config.old. In that file the password is stored.
9. switch: boot
10. Enter "n" at the prompt to abort the initial configuration dialog
11. Type en to enable
12. Switch#rename flash:config.old flash:config.text
13. Switch#copy flash:config.text system:running-config
14. Overwrite the current passwords:
conf term
enable secret <new pass>
enable password <new pass>
line vty 0 15
password <new pass>
login
line con 0
password <new pass>

15. write memory
16. copy run start
