Simulate re-cabling

[Nishanth Shyamkumar]

I am trying to change my L2 connection between the hosts on my slice.

Initially, I had 2 L2 STS links
h1 <—> h3 <—> h2

I then deleted the 2 links and created a new L2STS directly connecting hosts h1 and h2
h1 <—> h2

The new L2 object was created but it’s status is showing as ‘None’, instead of ‘Active’.

ID	Name	Layer	Type	Site	Subnet	Gateway	State	Error
None	net_h1_h2	L2	L2STS	None	net_h1_h2.subnet	net_h1_h2.gateway	None

How do I activate this link ? I think I should use slice.submit() , however I do not want to rebuild the nodes and other components on the slice, only the network connection. Would slice.submit() be the right command to rebuild only the network link , or is there some other issue that’s causing the state ‘None’ ?

Nishanth,

Yeah, I think you just need to call slice.submit() after you make the changes.  When you make changes like in fablib, it is just building the request. In order to commit the changes, you need to submit the modified request.

Hi Paul,

Do you know if the slice.submit() would rebuild all the VMs and network components or will it correctly update only the L2 link information? I don’t want to lose the files and environment setup on my VMs due to a slice rebuild.

It will not. It will do a diff between the existing topology and the one you want and make the necessary changes. In some cases it may reboot the existing VMs.
