Hello, thanks for your patience here. The instructions for how to change the default username was mistakenly left out of the product documentation, it's been added to an upcoming release. The rest of the information below came from the VOSS User Guide.
The “no password access-level <word>” command can be used to disable access levels other than the RWA.
Block CLI access to Layer 1:
Switch:1>enable
Switch:1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch:1(config)#no password access-level l1
Removing a created user is captured in the “Creating Multiple CLI Users” subsection of the VOSS User Guide:
Delete a user:
Switch:1>enable
Switch:1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch:1(config)#no username smith
The specified username will be deleted! Contiune (y/n) ? Y
Switch:1(config)#show cli username smith
Username does not exit
Change the default username:
Switch:1>enable
Switch:1#config t
Enter configuration commands, one per line. End with CNTL/Z.
Switch:1(config)#username EXUser ?
level Which access level
Switch:1(config)#username EXUser level ?
l1 Change Layer 1 read write enable password
l2 Change Layer 2 read write enable password
l3 Change Layer 3 read write enable password
ro Change read only enable password
rw Change read write enable password
rwa Change read write all enable password
Switch:1(config)#username EXUser level ro
Do you want to change username for the default RO user ? (y/n) ? y
Enter the old password : **
Enter the New password : *****
Re-enter the New password : *****
Hope that helps!
