What command can be used to determine the amount of physical RAM installed in a Cisco ISR 4000 router running IOS-XE 16.9.x?
router
I have a number of 4400 and 4300 routers and am trying to determine how much physical RAM is installed in each. This is proving to be amazingly more complicated than I thought. This document is not clear, as it says to use "show vesion" which is clearly not right based on the output I am seeing below.

They all show the same output for "show version", which is what the document says to use to determine physical RAM. For example, the following 4451 has 16GB physical RAM, while the 4331 has 4GB physical RAM.
