Switch Infrastructure Diagnostics
Avid ISIS supports system level diagnostics for every Avid ISIS switch from one location. The diagnostics organize
results and provide a report of problems with the switch.
The Switch Diagnostics test does not fix diagnosed problems; instead, it looks for problems and provides clues as to
the root cause. In many cases, the diagnostics can point to what the problem might be, where the problem is located,
or how to address the problem. However, diagnostics cannot always determine the cause of the problem, and the test
only reports relevant data for further analysis.
The diagnostic tests are organized into separate groupings. Each group investigates the switch in different ways to
look for possible problems. If you are unsure if you have a problem or where a problem is, select all the test groups
to get a more complete picture of the system's health. Each test exists in only one group. The following sections
describe how the tests are arranged within the groups.
Stacking
The Stacking test group looks for symptoms of a problem with switch stack health. Run this group of tests if you
think a switch is not properly stacked, or if you are having trouble with traffic flow on a particular switch.
Stack MAC Addresses
This is a report of MAC addresses for all Layer 2 visible switches in the stack from the reporting switch’s
perspective.
When the number of switches reported here is less than the number of switches reported by the Stack Serial
Numbers Test, there could be problems reaching a switch that is supposed to be part of the stack. Sometimes this
information can be verified by a failure in the Ping Stack Test. Or, if there is an extra switch listed in Stack Mac
Addresses, it could mean that a switch is visible that is not yet part of the stack and may need to be added.
State Machine
When switches connect to each other to form a stack, they go through a state machine process. If the two switches
have successfully completed their state machine process, they both reconcile to state STACKED. Switch
Diagnostics will report any switches that have not reconciled to this state.
n
If Diagnostics is run immediately after connecting two switches together, then those switches might still be going
through the normal state machine process and might not yet be reconciled. So, if Diagnostics is reporting an error in
the State Machine Test, and the two switches were just connected, try waiting about 5 minutes and run Diagnostics
again.
