DHCP req between ONIE and ONL

[Sridhar Pitchai]

Hi,

one of the customer is facing issue with DHCP IP being different between ONIE and ONL. the only difference we noticed is when on ONIE mode DHCP request has "dhcp-client-identifier" where as  ONL DHCP request does not. 

I can manually add, to address after onl comes up.

"

root@localhost:/etc/dhcp# cat /etc/dhcp/dhclient.conf | grep client-id
send dhcp-client-identifier "\001\3147\253\340\236\317";

" 

How to address it in ONL by default to set the dhcp-client-id just like ONIE ?

any suggestion. 

Thanks,

Sridhar

Sridhar, 

On your system, from ONIE, can you run the following a give me the output?

ONIE:/ # sh -x /etc/init.d/networking.sh

Sridhar, 

Are you using the deb7 or deb8 version of ONL?

Sridhar, 

In Deb8 you can use the -i option to dhclient to send the client id. I assume you've tried this and the difference in format between udhcpc's option 61 and dhclient's option 61 is still causing an issue?

Hi Jeff,

What we did is updated dhclient.conf manually. 

“

root@localhost:/etc/dhcp# cat /etc/dhcp/dhclient.conf | grep client-id

send dhcp-client-identifier "\001\3147\253\340\236\317”;

“

what we are looking for is to set the DHCP on ONL such a way that client-ID is sent out automatically just like ONIE udhcp. 

I was thinking if we can update the etc file with a higher priority init script which update this option before networking is invoked, not sure if this the best option. can you suggest how to sort this out.

Thanks,

Sridhar 

[Jeffrey Townsend]

Sridhar, 

I understand what you did. What I would like to know is does dhclient -i also solve the problem?

Let me quickly test it out and get back.

Hi Jeff,

dhclinet -i client ID format is different from ONIE as you pointed out. that did;t helped.

ONIE:

Sridhar, 

Please see the following commit. The system now populates dhclient.conf with the appropriate client-id for ma1.
