Release Y.11.15 Enhancements

Release Y.11.15 includes the following enhancements. (Not a public release.)

■ Enhancement (PR_0000018479) — Longer usernames and passwords are now allowed,

and some special characters may be used.

Username and Password Size Increase

For security reasons, it is desirable to allow the configuration of longer usernames and passwords

than is currently allowed on the switch. The limits on length will be extended to 64 characters for

the following authentication methods:

■ Front-end—WEB User Interface, SSH, and Telnet

■ Back-end—RADIUS, TACACS+, and Local

General Rules for Usernames and Passwords

Usernames and passwords are case-sensitive. ASCII characters in the range of 33-126 are valid,

including:

■ A through Z uppercase characters

■ a through z lower case characters

■ 0 through 9 numeric characters

■ Special characters ‘ ~ ! @ # $ % ^ & * ( ) - _ = + [ ] { } \ | ; : ‘ “ , < > / ? (see Restrictions, below)

The SPACE character is allowed to form a username or password pass-phrase. The username must

be in quotes, for example “The little brown fox”. A space is not allowed as part of a username

without the quotes. A password that includes a space or spaces should not have quotes.

Restrictions for the Setmib Command

Usernames and passwords can be set using the CLI command setmib. They cannot be set using SNMP.

■ Quotes are permitted for enclosing other characters, for example, a username or password

of abcd can be enclosed in quotes “abcd” without the quotes becoming part of the username

or password itself. Quotes can also be inserted between other characters of a username or

password, for example, ab”cd. A pair of quotes enclosing characters followed by any

additional characters is invalid, for example, “abc”d.

■ Spaces are allowed in usernames and passwords. The username or password must be

enclosed in quotes, for example, “one two three”. A blank space or spaces between quotes

is allowed, for example, “ ”.
