The Cisco Nexus 5000 and 6000 Series switch does not support all numeric usernames, even if those
usernames were created in TACACS+ or RADIUS. If an all numeric username exists on an AAA server
and is entered during login, the switch rejects the login request.
Usernames must begin with an alphanumeric character and can contain only these special characters: ( +
= . _ \ -). The # and ! symbols are not supported. If the username contains characters that are not allowed,
the specified user is unable to log in. Effective from Cisco NX-OS release 7.3(0)N1(1), usernames starting
with _(underscore) are supported.
