Security
For example, to give a user access to modules and ports, event management,
layer 2 switching, and routing, you would enter a hexadecimal value of
08888000 (0000 1000 1000 1000 1000 0000 0000 0000 binary).
* Note: Only bits 12, 16, 20, 24, and 28 are used in the CAT access
mask. Set all other bits to 0. If you inadvertently set other bits
in the mask, the switch ignores them . The remaining bits in the
mask are reserved for future use.
If you enter a mask of all zeros (00000000), the user can view general
system information but cannot configure any settings.
CAT Read-Only
Mask The CAT read-only mask specifies the read-only access ible features for a
custom access type.
The mask is a 32-bit hexadecimal value. To specify read-only access for a
particular feature, you set the appropriate bit. Each feature is assi gned to the
same bit as the access mask. See Table 4 -2.
The corresponding bit in the CAT access mask must also be set. If the
access mask bit is set, but the same bit in the read-only mask is set to 0, th e
user has read-write access to the pa rt icular feature.
For example, to give a user read-write access to modules and ports and
event management, and read-only access to layer 2 switching and routing,
you would enter the following values:
■CAT access mask—08888000 hexadecimal (0000 1000 1000 1000
1000 0000 0000 0000 binary).
■CAT read-only mask—08800000 hexadecimal (0000 1000 1000
0000 0000 0000 0000 0000 binary).
* Note: Only bits 12, 16, 20, 24, and 28 are used in the read-onl y mas k.
Set all other bits to 0. If you inadvertently set other bits in the
mask, the switch ignores them. The remaining bits in the mask
are reserved for future use.
