AutoTracker Policy Types
Page 20-2
AutoTracker Policy Types
You can define a maximum of 32 AutoTracker policies of each type per Group. There is no
restriction on the number of rules you can define per AutoTracker
VLAN
, as long as the maxi-
mum number of policies for the Group is not exceeded. A port or device is included in a
mobile group or AutoTracker
VLAN
if it matches any one rule.
You can define the following types of rules:
Port Policies
. Port policies enable you to define membership on the basis of ports. Members of
the mobile group or AutoTracker
VLAN
will consist of devices connected to specific ports on
one switch or on multiple switches in the Group.
MAC Address Policies
.
MAC
address policies enable you to define membership on the basis of
devices’
MAC
addresses. This is the simplest type of rule and provides the maximum degree of
control and security. Members of the mobile group or AutoTracker
VLAN
will consist of
devices with specific
MAC
addresses. These devices may all be connected to one switch or
they may be connected to different switches in the Group. A maximum of 1024
MAC
addresses are supported per
MAC
address policy.
Protocol Policies
. Protocol policies enable you to define membership on the basis of the proto-
col that devices use to communicate. All devices that communicate with the specified proto-
col become members of the mobile group or AutoTracker
VLAN
.
You can specify membership according to the following protocols:
IP
,
IPX
, AppleTalk, or
DECN
et. In addition, you can specify membership according to Ethernet type, source and
destination
SAP
(service access protocol) header values, or
SNAP
(sub-network access proto-
col) type.
Network Address Policies
. Network address policies enable you to define membership on the
basis of network address criteria.
For example, you can specify that all
IP
users with a specific subnet mask be included in the
mobile group or AutoTracker
VLAN
. Or, you can specify that all
IPX
users in a specific
network address area using a certain encapsulation type be included.
If you define network address and port or protocol rules in the same
VLAN
, the network
address rules will take precedence over the port and protocol rules should any conflict arise.
To reverse this precedence (i.e., port and protocol rules take precedence over network
address rules) you must add the following line to the switch’s
mpx.cmd
file:
Precedence=0
User-Defined Policies
. User-defined policies enable you to define membership on the basis of a
specific pattern within a frame. All devices that originate frames containing this pattern are
assigned to the mobile group or AutoTracker
VLAN
. The pattern is specified by defining an
offset, a value, and a mask.
Port Binding Policies
. A port binding policy specifies a particular device to be included in the
mobile group or AutoTracker VLAN. There are six types of Port Binding Rules that can be
created:
• Bind IP Address to a Port and a MAC address
• Bind MAC Address to a Protocol and a Port
• Bind Port to a Protocol
• Bind IP Address to a MAC Address
• Bind IP Address to a Port
• Bind MAC Address to a Port
