Configuring XServe LOM using ipmitool

I recently attempted to configure the LOM on 3 Xserve systems.

On 2 I used the Server Monitor and was able to get things to work. On the third I decided to use the ipmitool to set the addresses but I can't seem to get it to work. Unfortunately, after this attempt, the Server Monitor also does not seem to get things working anymore.

Here are the ipmitool commands that I used:

ipmitool lan set 1 ipaddr <ipaddress>
ipmitool lan set 1 netmask <netmask>
ipmitool lan set 1 defgw ipaddr <gateway>
ipmitool lan set 1 access on

Check the settings using
ipmitool lan print 1

Get the admin userid.
ipmitool user list 1

Set the password
ipmitool user set password <userid> '<password>'
ipmitool user enable <userid>

When I try to connect to the LOM from another system the remote controller does not respond

ipmitool -v -v -v -H strmac18-c -a -U admin chassis power status
Password:
...
No response from remote controller
Get Auth Capabilities command failed

Can someone please let me know if I am missing something in the configuration?

Thanks a lot in advance for the help.
