Switch/Router health

If one wants to check the health of a switch or routers just to see that everything is ok with it, what should someone check.

here is my list

Show system

Show proc cpu/mem

show env all/power

show log

What else can someone check?

Thanks

Re: Switch/Router health

When a switch component exhibits symptoms of possible hardware failure, additional diagnostics tests should be performed to confirm the issue is hardware related and rule out other causes of the symptoms.

Some tests disrupt network activity, so it is important to verify that the test you run does not affect your current network traffic.

Runtime diagnostic checks can be run on demand or scheduled to run at a specific time. They can run continually in the background. When a module or supervisor exhibits failure symptoms or an error message is received, the test can usually be performed on demand.
