I have Cisco 2501, running IOS 11.2(18). I am trying to configure DHCP. When I typed "no ip dhcp conflict logging", I got the error message: Translating "conflict"...domain server (165.8.1.8) (165.8.1.1)
^
% Invalid input detected at '^' marker.
When I typed "ip dhcp pool ls", I got the error message:
Translating "pool"...domain server (165.8.1.8) (165.8.1.1)
^
% Invalid input detected at '^' marker.
Do you have any suggestions? Thanks.

Hi - you'll need to disable ip domain lookup, here's an example, the config below is on a c1600 IOS 12.1(6). This router is being used as a DHCP Server, modify the below config for your network and you should be okay to go.
ip subnet-zero
no ip finger
no ip domain-lookup
no ip dhcp conflict logging
ip dhcp excluded-address 192.x.x.x 192.x.x.x
ip dhcp pool internalnetwork
network 192.x.x.x
default-router 192.x.x.x
domain-name
dns-server
netbios-name-server
netbios-node-type h-node
lease 10
Hope this helps / Jay.

I typed "no ip-domain lookup", it accepts it. However, when I typed "no ip dhcp conflict logging", I still got the same error message.
Do you have any suggestions?
Thanks.

When you are typing "no ip dhcp conflict logging" the router is interpreting the word "conflict" as a hostname not a keyword. Same thing with "pool". By disabling domain-lookup you will won't get the same message, but you will still have a problem most likely.
With 11.2(18) code, I'm not sure that functionality is available. I would try using the trusty ? after the commands you are having trouble with try typing "no ip dhcp ?" and "no ip dhc?". This will tell you whether or not that command is actually available or not.
Hope this helps.

You are right. By typing "no ip domain-lookup", I no longer got the same message. But, I still have the problem.
By typing "no ip dhcp?" or "no ip dhc?", I got a return message: dhcp server. Does it mean it will accept dhcp?
Thanks.

IOS DHCP was released into IOS 12.0. You will need to upgrade your IOS for this functionality. The following link shows the new features introduced by 12.0 mainline and "Cisco IOS DHCP" is one of them.
http://www.cisco.com/en/US/products/sw/iosswrel/ps1830/products_feature_guide09186a008008089d.html
Scroll down to the C's and click on Cisco IOS DHCP for configuration guidelines.
Hope this helps,

Thank you for the information.
I am trying to upgrade the flash to ver. 12 (file name: c2500-8-l.120-5.T2.bin) on Cisco 2501. After typing "config-reg 0x2101" and "reload", the router came back with the prompt as
hostname(boot)>
Then, after typing "copy tftp flash", I got the following screen:
hostname(boot)#copy tftp flash
Flash: invalid chip id 0x9105
unable to configure flash for erase or write.
Flash chips recognized by system :

The hostname(boot)# indicates that your router has loaded an image from bootflash vise the standard image in the flash. issue the command
show boot
to see what you are booting with. Next check the flash to see if that image reflects
dir flash:
Next if the image is different in flash than it is from what show boot told you, issue the following command to boot from the image in flash (from the global config, config t)
boot system flash:imagename.bin
Next continue the upgrade as usual:
copy tftp flash
Let me know if you still have problems.

Do you want me to do the next step which is to type the command "boot system flash:imagename.bin"?
Thanks.

Feature navigator is a good tool to use.

It sounds like the DHCP command that you want is not available on the image you are using. To see the options available, enter "ip dhcp
?"
03-08-2004 08:56 AM
Thanks for the info.
When I typed the command ip dhcp ?, it responded with:
hostname(boot)#ip dhcp?
hostname(boot)#ip dhcp

Why are you doing this from the boot config prompt?
03-08-2004 11:06 AM
I don't know why the router booted from the boot config. I tried to upgrade the IOS.
03-08-2004 04:49 PM
The messages in your posting of Mar 3 at 7:03 are reporting problems with the flash. Did you upgrade the flash to enable the IOS upgrade? I think you have a very old 2501 and the boot rom (yours is 9.14(6) needs to be upgraded to handle the extra flash.
03-08-2004 07:18 PM
No, I did not upgrade the flash. How do I upgrade the flash? Thanks.
