Note The syntax of the configuration commands and their
‘no’ forms are often different; the
‘no’ forms usually only takes as many parameters as is necessary to unambiguously identify
the entity to reset/remove
and the remainder of input is ignored.
This is usually convenient but may give surprising results in certain cases. For example, an
OAM MEP instances can configure Continuity Check using ‘
mep num cc priority
...’ and
reset it with ‘
no mep num cc
’. However, since MEPs are removed using the command ‘
no
mep num
’ it is possible to unintentionally remove an existing MEP by entering ‘
no mep 10
ccc
’ – the extra ‘c’ means that the last word isn’t recognized as ‘cc’, leading to a match of the
MEP removal command instead of the desired reset-CC command.
5. Managing Users
The following describes local user management on the device. RADIUS and user
management is beyond the scope of this document.
It is possible to create several user accounts on a system. Each user account has a set of
configurable attributes:
 User name
 Password
 Privilege level
All attributes are configured with the same command, username .
username username privilege level password { unencrypted | encrypted } password
username username privilege level password none no
username username
The command password none is used when no password is desired. The security
implications of using this should be considered carefully. Likewise, no username deletes the
given user account.
Example 9. Adding, Modifying and Deleting Users
The following example adds two user accounts at different privilege levels, inspects
configuration, and deletes one account again using ‘no username’.
