Hi Milind,

i dont know about the max limitation of the username but 5 username is not an issue.

you can configure the usename with this command.

>enable

#

# config terminal

# usename ***** password ***

or for encry

username ***** secret 0 to 5 *******

0-5 is level type any one.

keep using same command for all users

no delet them say no and command.

no username ****** password *****
