This question is in regards to mac-address sticky.
I thought the purpose of the sticky command was to be used when you have a device plugged into the port to capture the mac-address so you don't have to manually enter the mac-address? If it is, then I am doing something wrong.

Sticky keeps the mac address in the running config, and if a wr mem is performed, it will be there when there is a reboot. As HH said, is there a mac address in the running config? _________________ kidvelvet www.kidvelvet.net
Yes, your problem is the most important. Just like everybody else's.

No. I didn't put a mac address in, I was just doing a lab with two laptops and noticed when I connected them I had to always manually configure the mac-address. _________________ FJohnson

first tried it with the sim, but no part of the commands would work. Then tried it with my live rack, everything worked except for the sticky, where I had to input the mac-address manually.
basically if I had 12 workstations plugged in it would be hard to run to each machine and input each mac-address. _________________ FJohnson

May I ask why 2? what I have read was that if you have the machines plugged in and then you put in the sticky command it captures that specific mac-address and stores it so no other device can connect. _________________ FJohnson

It worked. Ok so I had the devices unplugged then I set the maximum to 2 and input the other commands. I then plugged in two separate devices and did the "show run" and saw the mac-address in the config. I then swapped the devices to test it and sure enough it worked.
So I guess that is the answer to my question. You have to have the devices unplugged before you do the commands. _________________ FJohnson
