Port-security mac-address vs. mac-address sticky?

Hey all,

I understand that with port-security the sticky command allows the switch to
dynamically learn MAC addresses and save them to the running config as
"switchport port-security mac-address sticky 0000.000c.0001" as an example.
What I was curious though is in all the books and CBTs I have seen, the
author/instructor always manually enters MAC addresses using the sticky
command, not just "switchport port-security mac-address 0000.000c.0001."

If you are manually configuring the MAC addresses for port-security, is
there any difference between:
switchport port-security mac-address 0000.000c.0001 and
switchport port-security mac-address sticky 0000.000c.0001?

In my testing I do not seem to see any difference, so I am curious if anyone
knows of a difference, or are they the same if you are manually configuring
the MAC addresses?

Thanks,

Eric
