Accessing zendmd to change iface speed on Zenoss 5

Trying to set the speed of several interfaces. They are 1 GB but are modeled at 10 mb. Remodel doesn't help.

I can't figure out how to run this script in Zenoss 5

I've ran it before in 4.2.6, but I don't know how to get to zendmd in Zen 5. I can log into my zenoss box as root.

Any help out there

Much thanks.
