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
VLAN
s. 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
VLAN
s. If you want devices
from switch 1 included in switch 2’s VLAN s, 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)

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.
