Defining and Configuring AutoTracker Policies

For example, if you enter FFEF as the value and FFFF as the mask:
Hex Binary
Value= FFEF = 1111 1111 1110 1111
Mask= FFFF = 1111 1111 1111 1111
When a bit in the mask is set to 1, the corresponding bit of the value must be literal.
When a bit in the mask is set to 0, the corresponding bit in the value is ignored and can
be either a 0 or a 1. In the example above, since the mask is
FFFF , all bits in the value
must be literal and the actual pattern searched for is the binary value 1111 1111 1110
1111. Only devices that originate frames containing this binary value beginning at the 21st
byte will be included in the mobile group or AutoTracker
VLAN .
As a second example, if you enter FFEF as the pattern and FFF7 as the mask:
Hex Binary
Value= FFEF = 1111 1111 1110 1111
Mask= FFF7 = 1111 1111 1111 0111
In this example, bits 0–2 and bits 4–15 of the value must be literal, since the correspond-
ing bits in the mask are 1s. However, since bit 3 of the mask is a 0, bit 3 of the value can
be either a 0 or a 1. Therefore, in this example, two actual binary patterns are searched
for:
1111 1111 1110 1111 or 1111 1111 1110 0111
Devices originating frames containing either one of these binary values beginning at the
21st byte of the frame will be included in the mobile group or AutoTracker
VLAN .
6. The following prompt displays:
Configure more rules for this vlan (y/n):
You can set up multiple rules for the same mobile group or AutoTracker VLAN . Enter a Y
here if you want to set up more rules in addition to the Network Address rule specified
here. If you enter
Y , you will be prompted for the next rule that you want to set up on
this mobile group or AutoTracker VLAN . Follow the directions in the appropriate section
to configure that rule.
If you enter N , you will receive a message, similar to the one below, indicating that the
VLAN was set up.
VLAN 1:2 created successfully
You are done setting up rules for this mobile group or AutoTracker VLAN.
