 DHCP: No allocation possible
C2611XM, Cisco 2611, DHCP Lease Renewal, DHCP server, IOS commands, Networking, Networking in 2010
Hey, I'm having issues with a c2611XM acquiring an ip address via DHCP
I've tried different IOS Versions,
different DHCP Server software on multiple operating systems,
fresh configs,
different MAC address,
client-identifiers
-This current setup is
Client:  C2611XM
Server: C2611XM (GNS3 Emulated)
Both configs are fresh except
ip dhcp pool test
   network 10.0.0.0 255.255.255.0
on server and
int fa0/0
   ip address dhcp
on client
I've tried Linux dhcp, ISP cable DHCP, Tftpd DHCP,  Netgear router
DHCP and a few other servers with all same client output
I'm starting to think this is some hardware issue
heres debugs for client and server

I was having exactly the same problem, what I find out is that I have the same vlan under the switchport access, and switchport voice commands. I reconfigure the switchport access with another vlan and problem solved.
