Adding/editing device interface descriptions

Good morning!

This is likely very simple, but I can't seem to find the answer - perhaps my Google-fu is weak today......

I have a number of network devices I monitor through Zenoss Core. They have a label and, if configured, an IP address. However, there is not a helpful description for these interfaces.

Can I add or edit this field for the interfaces on a device If so, where is the starting point for this

Thanks to all in advance!
