All traffic entering switch 1 from the backbone
port, port 3-1, is checked against switch 1’s poli-
cies for VLAN membership in the Group(s) being
trunked. In this example only Group 1 is being
trunked, so traffic is checked against the VLAN
policies defined for Group 1’s VLANs. If you want
devices from switch 2 included in switch 1’s
VLAN

s, you must define policies on switch 1 that

will so include them. In this example, an IPX pol-

icy was defined for VLAN 2 and

a n I P p o l i c y w a s

defined for VLAN 3.

Group 1

Slot 2 Port 1

All traffic entering switch 2
from the backbone port, port 3-1, is
checked against switch 2’s policies for VLAN
membership in the Group(s) being trunked. In
this example only Group 1 is being trunked, so
traffic is checked against the VLAN policies
defined for Group 1’s VLANs. If you want devices
from switch 1 included in switch 2’s VLANs, you
must define policies on switch 2 that will so
include them. In this example, an IPX policy was
defined for VLAN 2 and an IP policy was defined
for VLAN 3.

An Example of

VLAN Assignment Using Logical Policies and

Current Port Policy Functionality (

reg_port_rule = 0)

VLAN 3

Port rule: 3-1

Protocol rule: IP

(assigns devices C & D)

(assigns no devices)

VLAN 2

Port rule: 3-1

Protocol rule: IPX

(assigns devices A & B)

(assigns no devices)

VLAN 3

Port rule: 3-1

Protocol rule: IP

(assigns devices C & D)

(assigns no devices)

VLAN 2

Port rule: 3-1

Protocol rule: IPX

(assigns devices A & B)

(assigns no devices)

Slot 2 Port 2

Because the back-
bone port, port 3-
1, is assigned to
VLAN

s 2 and 3 in

switch 1 via a port
policy, traffic can
flow out of these
VLAN

s onto the

backbone.
