some c6320 nodes might have link issue

[Miao Yu]

I've been using small-lan profile. I've noticed some nodes in c6320 tend to have link issue when connecting with private ip (I'm still able to ssh onto those nodes)

Example: create a 2-node small-lan experiment, then run linktest

(attaching uuid in case you want to look at logs)

An experiment with clnode131 and clnode105 failed linktest  (uuid=fd17075a-8e15-11ed-b318-e4434b2381fc)

Another experiment with clnode107 and clnode 102 failed linktest (uuid=7e064f4e-8e3e-11ed-b318-e4434b2381fc)

Hi. The best way for us to help you out with this problem is to
send us the URL of the status page while the experiment is running
so we can take a look.

Thanks
