What is sysDescr?
This is a text string (up to 255 characters) that describes the device's hardware, operating system, and software versions. A network engineer uses this to quickly identify what type of device is being monitored and verify that it is the expected version. For example, you might see 'Cisco IOS Software, C2960X Software, Version 15.2(4)E5, RELEASE SOFTWARE' to confirm you are monitoring the right switch.
