Hello,
This may be a very basic question but I am brand new to Cisco IOS. I have been tasked with figuring out how to release and renew all dhcp addresses on our Cisco 2921 router. I have so far found out how to do them one at a time using:
Router# release dhcp ethernet 3/1
Router# renew dhcp Ethernet 3/1
Would rebooting the router release and renew all of the dhcp addresses? If not, is there a command I could use to release and renew all of them at the same time?
Thank you.

Try this from priviladge mode
router#clear ip dhcp binding *

Hi,
You are a DHCP client on multiple interfaces ? if so doing a shut/no shut on the range of interfaces would achieve what you want and you could automate it with an EEM script.
