I am having a hard time understanding this redox equation.
Hg_{2}Cl_{2} > Hg_{2}^{2+} + 2Cl^{}
What are the oxidation numbers for all the elements in this equation?

Hg2Cl2 > Hg22+ + 2Cl
+1 ,1> 2+ , 1
sorry, I am not sure if it's right

I am having a hard time understanding this redox equation.
There is no redox reaction here, this is simple dissociation. Both Hg in Hg2(2+) can be trated as +1.

But here http://www.qivx.com/ispt/elements/ptw_080.php it says it is a redox equation. Also, I took the equation from a chemistry problem in which you have to identify dismutations among a number of given equations, and this was one them. The solution to the problem says this is not a dismutation but I don't understand how it is a redox equation either.

But this link shows this reaction:
Hg2Cl2 + 2e => 2Hg + 2Cl
