port to automatically determine the fastest settings the device the port is connected to can handle, and
then to use those settings. The other options are 100M/Full, 100M/Half, 10M/Full, and 10M/Half.
There is no automatic adjustment of port settings with any option other than Auto.

Port Locking

A given port's (or a range of port's) dynamic MAC address learning can be locked such that the current
source MAC addresses entered into the MAC address forwarding table can not be changed once the
port lock is enabled. The port can be locked by toggling the Lock field to Enabled, highlighting APPLY

Highlight APPLY and press Enter to make the changes current.
