What is the difference between the "Device Refresh Schedule" set via the
ZLM server web page and the "refresh-interval" on the ZMD client on my
managed devices?

I tried overriding the "Device Refresh Schedule" on one of my managed
devices to 5 minutes, however, the "refresh-interval" on the ZMD client is
still set to 86400 seconds.

What are the difference between these to "refresh" settings?
