This was missed in testing the GPO and RENCI racks administrative access.

Having administrative access to the head node allows user to login to the management and dataplane switches, but does not allows "enable" access (Turn on privileged commands):

lnevers@uh-hn ~]$ id
uid=2107(lnevers) gid=2000(nonrenci) groups=2000(nonrenci),2501(uhadmins),9510(bbnadmins)

[lnevers@uh-hn ~]$ ssh lnevers@uh-8264.uh.xo
Enter radius password: 

IBM Networking Operating System RackSwitch G8264.

uh-8264.uh.xo>ena

Enable access using (oper) credentials restricted to admin accounts only.
uh-8264.uh.xo>exit

...

[lnevers@uh-hn ~]$ ssh lnevers@uh-8052.uh.xo
Enter radius password: 

IBM Networking Operating System RackSwitch G8052.

uh-8052.uh.xo>ena

Enable access using (oper) credentials restricted to admin accounts only.

Finding TCP traffic results are inconsistent for site to site connection set up by the ExoSM stitching between the GPO and Houston rack.

The following TCP performance was found from GPO EG to Houston EG (repeatable):

   1 TCP client = 20.4 Mbits/sec 
  5 TCP clients = 3.02 Mbits/sec
 10 TCP clients = 2.98 Mbits/sec

Why does throughput drop from 20 Mbits/sec as more client are added?

These are the results for the same requests in the opposite direction from Houston EG to GPO EG:

   1 TCP client = 7.95 Mbits/sec
  5 TCP clients = 8.81 Mbits/sec
 10 TCP clients = 8.66 Mbits/sec

Why such low throughput for an ExoSM VLAN?

The results above are inconsistent compared to other sites.

From GPO EG to UFL EG:                         
   1 TCP client = 27.5 Mbits/sec
  5 TCP clients = 139 Mbits/sec
 10 TCP clients = 278 Mbits/sec

From UFL EG to GPO EG:
   1 TCP client = 27.5 Mbits/sec
  5 TCP clients = 129 Mbits/sec
 10 TCP clients = 201 Mbits/sec

This issue was first reported on Dec 6, 2013. Writing ticket to track to resolution.

I just checked to verify the state of this issue and to capture output for this ticket and found that there is now a different failure:
