NOTE

Note the following:
• The default Read mode for the Secure XML SNMP and Insecure XML SNMP
management channels must be identical to their read permission.
• Read permission Exclude is allowed only for Secure XML SNMP and
Insecure XML SNMP management channels; Exclude is not allowed for
regular secure and insecure channels.
• Exclude sensitive data in secure and Insecure XML-SNMP management
channels means that the sensitive data is presented as a 0 (meaning null
string or numeric 0). If the user wants to view sensitive data, the rule must
be changed to plaintext.
• By default, an SNMPv3 user with privacy and XML-over-secure channels
permissions is considered to be a level-15 user.
• SNMP users on Insecure XML and SNMP (SNMPv1,v2, and v3 with no
privacy) channel are considered as All users.
• SNMP community names are not used as user names to match SSD rules.
• Access by a specific SNMPv3 user can be controlled by configuring an
SSD rule with a user name matching the SNMPv3 user name.
• There must always be at least one rule with read permission: Plaintext Only
or Both, because only users with those permissions are able to access the
SSD pages.
• Changes in the default read mode and read permissions of a rule will
become effective, and will be applied to the affected user(s) and channel of
all active management sessions immediately, excluding the session making
the changes even if the rule is applicable. When a rule is changed (add,
delete, edit), a system will update all the affected CLI/GUI sessions.
When the SSD rule applied upon the session login is changed from
NOTE
within that session, the user must log out and back in to see the change.
When doing a file transfer initiated by an XML or SNMP command, the
NOTE
underlying protocol used is TFTP. Therefore, the SSD rule for insecure
channel will apply.
SSD Rules and User Authentication
SSD grants SSD permission only to authenticated and authorized users and
according to the SSD rules. A device depends on its user authentication process
to authenticate and authorize management access. To protect a device and its
data including sensitive data and SSD configurations from unauthorized access, it
