Defining Your Own Rules
A user-defined rule enables you to include all devices in the mobile group or AutoTracker
that originate frames containing a specified pattern at a specified location. Each user-
VLAN
defined rule requires an Offset, a Value, and a Mask; you will be prompted for each of these
values. The Offset specifies the location of the pattern within the frame. The Value specifies
the pattern. The Mask specifies the bits that you care about within the Value pattern.
After you enter the Administrative Status for this mobile group or AutoTracker
following menu displays:
1. Enter and press
2. The following prompt displays:
Indicate whether or not you want to enable the Administrative Status for this rule. Type
to enable or to disable. If you enable the rule, the switch will use it to determine
membership of devices. If you disable the rule, then the switch will not use this rule, but
the parameters you set up will be saved. The Admin Status for a Policy is different from
the Admin Status for the mobile group or AutoTracker
specific rule. You can enable or disable the rule at a later time using the
command.
3. The following prompt displays:
Enter an value, in number of bytes, to define the location where the
pattern – is found. The offset value can be any number from 0 – 63. The first byte of the
frame's header is considered byte 1. An offset of 0 specifies that the pattern begins in
MAC
byte 1 of the frame.
As an example, enter an offset value of
, because that pattern begins in the 21st byte of the frame.

4. The following prompt displays:
Enter a , in hex, to specify the pattern itself. The value can be a maximum of eight
bytes. For example, enter

entered. The mask value is
