How to view DHCP lease from ISP on a 2811

I have a remote site on a 2811 IOS 12.4(15).  Interface FA 0/0 faces the ISP and is set for DHCP.  What command can I run to see all of the information given out with the IP lease from the ISP?  I need to find out what the IP address of the DNS servers are. 

All responses appricated. 

Cheers,

Frederick Sawyer

Not sure about an ios command, but if you can take a downtime and hub out or tap the line and do a packet capture on it, you'll get all the dhcp information you want.

Just a thought.

Hi,

to see traffic he can also use the RITE feature: http://www.cisco.com/en/US/docs/ios/12_4t/12_4t11/ht_rawip.html

Hi,

Try the command "show dhcp lease"

Also "show dhcp server" is useful as well.
