How do I list user accounts on a Cisco SAN Switch with commands?

All:

I created a new user with the following commands:

     switch# config terminal

     switch(config)# username fedona password sox2004ch@mps role network-admin

And now I want to list the existing accounts to see if it was created. 

I can't find the command to do that.  Can anybody tell me what the command is, please?
