* The Read mode of a session can be temporarily changed in the SSD 
Properties page if the new read mode does not violate the read permission.
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.
NOTE When the SSD rule applied upon the session login is changed from 
within that session, the user must log out and back in to see the change.
