DHCP works fine on our 7206 running 12.1(11) with essentially the same config a
s yours. Try sh ip dhcp server stat and sh ip dhcp bind to see if the 7206 is d
oing anything with DHCP. Maybe it is something specific to the client?

Greetings,
I am on a client site and need help resolving an issue with DHCP. The
problem is that the 7206 receives a DHCPDISCOVER from the client, and then
does nothing. There are no connectivity issues; when the PC is hardcoded
with an IP address in the range offered by the server, it has full network
connectivity.
The 7206 is running 12.2(7) IP only software; image c7200-is-mz.122-7 and
the configs are as follows:
Production network info masked by X's, etc.
********************************************
7206:
service dhcp
!
no ip dhcp conflict logging (this used instead of defining a database)
ip dhcp excluded-address x.x.x.x x.x.x.x
!
ip dhcp pool dhcp_pool
network x.x.x.x x.x.x.x
default-router x.x.x.x
domain-name unlisted
dns-server x.x.x.x
!
interface FastEthernet0/0.5
encapsulation dot1Q 5
ip address x.x.x.x x.x.x.x
no cdp enable
!
******************************************
Catalyst switch:
#module 3 : 48-port 10/100BaseTx Ethernet
set vlan 2 3/1-47
set vlan 5 3/48
set trunk 3/48 off dot1q 1-1005
set spantree portfast 3/48 enable
*****************************************
Client attached to port 3/48.
The exact same configuration on a 3600 series router running the same IOS
works perfectly. I tried 2 different 7206 routers with identical configs
and received the same result:
*Mar 26 17:23:24.751: DHCPD: DHCPDISCOVER received from client
0100.10a4.b72f.28
on interface FastEthernet0/0.5.

*Mar 26 17:29:35.851: DHCPD: DHCPDISCOVER received from client
0100.10a4.b72f.28
on interface FastEthernet0/0.5.
*Mar 26 17:29:43.855: DHCPD: DHCPDISCOVER received from client
0100.10a4.b72f.28
on interface FastEthernet0/0.5.
*Mar 26 17:29:59.859: DHCPD: DHCPDISCOVER received from client
0100.10a4.b72f.28
on interface FastEthernet0/0.5.
Could there be a problem with the 7206 platform running a DHCP Service? CCO
was not any help, nor were there any caveats listed under the IOS release.
My apologies for the length, and thanks in advance for any advice.
