How do I find out if a command is supported

Generic question that I'm sure would have been answered, but the old Cisco tools don't work any more.

How do I check which commands are supported on a particular hardware platform?

For instance before I buy the equipment, how can I check that a certain command is supported?

The feature search doesn't seem to go down to the command level.

typically if its an IOS device the IOS feature set defines what is available and whats not.  

 

use the feature navigator,  i wont tell you commands but will tell you features:

Hi @echan101,

 

I hope this link can help you:

No unfortunately this is not helpful.

Even if I check the configuration guides, it tells me a when a command was introduced, but it doesn't tell me which platform actually supports that command.

Any other ideas?

Unfortunately the feature navigator doesn't go down to the command level as you say. And individual commands may not be supported in the feature set.


I ended up asking the question through TAC since I had an active contract on the same platform. Their answer was that the command (ntp update-calendar) wasn't supported on ISR4000 series routers as there is no onboard hardware clock (calendar = hardware clock).

There was no way of finding this out using the documentation. The only way was to ask TAC (since trying it out on the router is not a definitive way of proving something doesn't work - i.e. there's a possibility it can only be configured in a certain mode, or it could be a bug). TAC also provides an authoritative response which is important when reporting findings to management.
