    5656 1. In `Dashboard` click on the `Aggregates` button, this will display all known aggregates.
    5757
    58  2. Narrow down the list by typing "clemson" in the upper-right `Search` field, which will show only Clemson aggregates. As you can see from the Nodes and Slivers counts, the InstaGENI rack has the most activity and most likely the source of the issue.  So will we focus on clemson-ig:
     58 2. Narrow down the list by typing "chicago" in the upper-right `Search` field, which will show only Chicago aggregates. As you can see from the Nodes and Slivers counts, the InstaGENI rack has the most activity and most likely the source of the issue.  So will we focus on uchicago-ig:

    6262 3. We will use GENI reporting to find the VLAN that is the source of most traffic.  Select `GENI Reporting`-> `Reports`.
    63  4. On the resulting page select the "Report Type" `VLAN Network Throughput [By Aggregate] from the pull-down and in the "Report Target" type start typing "clemson", the field will automatically list all aggregate names that match, select "clemson-ig".
     63 4. On the resulting page select the "Report Type" `VLAN Network Throughput [By Aggregate] from the pull-down and in the "Report Target" type start typing "chicago", the field will automatically list all aggregate names that match, select "uchicago-ig".
    6464
    65  5. In the `Reports List` results section, choose the  report named "VLAN Network Throughput for Aggregate [clemson-ig]". The report will show VLAN usage for the aggregate form highest to lowest. Pick the highest usage VLAN ID. In this procedure we will choose VLAN 1234)
     65 5. In the `Reports List` results section, choose the Report Type named "VLAN Network Throughput [By Aggregate]", select the Report Target `uchicago-ig`, and the Report Range "Today".  The resulting report "VLAN Network Throughput for Aggregate [uchicago-ig]"  will show VLAN usage for the aggregate form highest to lowest for each VM Server Host interface in use. Following are the VLAN statistics report for one of the VM Servers:
    6666
    67  6. Go to `Dashboard` and click on the `Aggregates` button, this shows list of all known VLANs. Narrow down the list by typing "1234" in the upper-right `Search` field.  Results will now include AL2S and Clemson monitored VLANs.

    6868
    69  6. Select "instageni.clemson.edu_interface_pc3:eth2:1234" and you will get data metrics for the VLAN 1234 at Clemson IG.
     69 6. We are going to pick the highest usage VLAN ID on the VM Server PC2 using VLAN 3076):
    7070
    71  7. Go back to the list of VLAN Metric available and this time choose the AL2S entry "sdn-sw.atla.net.internet2.edu:eth5/2:1234"  to view statistics reported from the AL2S switch in Atlanta where Clemson is connected to AL2S Network.
