Autocad: how to duplicate a layer

This must be so simple, but it is driving me crazy.  I have a layer "Solution 1".  I want to create another layer "Solution 2" that starts out as a duplicate of "Solution 1".  IOW, I want to create a layer copy.  What is the quickest way to do this?  Thanks for any replies!

First copy the elements to another file (WBLOCK) or make a copy of the whole file with Windows Explorer.

Open the copy and use layer manager to rename the layer to the new name.

Then, insert copy file back into the original file (at the original coordinates or others) and explode it.

There are other ways but these are simple.  Alot depends on how much interference you have from other layers and nested blocks.  The above method will change the layer name of the top level element NOT anything that is nested inside.

like dhsindy said there are alot of ways to do what you want. if you have version 2000 + this is one way:
create your "solution 2" layer
use qselect to get everything on solution 1 selected.
use the copy command and use 0,0,0 for the base point, if you want everything in the same spot.
use the _pselect command at the prompt type p then enter, that will select everything you had selected previous.
then open the properties dialog and change the layer to the solution 2.

just another way to do it.
