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 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 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 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 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 

 file:

. 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.

. 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
