Devices that Generate a Secondary Traffic Type
Source devices sometimes generate more than one traffic type; for example, a device could
generate
IP
traffic primarily but also generate a secondary stream of AppleTalk. When a
device generates secondary traffic that does not match any existing
VLAN
policy, that traffic is
grouped into the primary
VLAN
of which the device is a member.
To continue the example, if a device generates both
IP
and AppleTalk, and both an
IP
VLAN
and an AppleTalk
VLAN
exist, that device is made a member of both
VLAN
s and no problem
occurs. If, however, an AppleTalk
VLAN
does not exist, all traffic from that device is grouped
into the existing
VLAN
of which the device is a member – in this example, the
IP
VLAN
. This
can cause communication problems, as explained below.
For this reason, it is advisable to
create
VLAN
s that accommodate all known network traffic.

In this example Device A is
assigned to default
VLAN
#1
because it does not match any
existing
VLAN
policy.
Devices B and C are assigned to
VLAN
2 because they generate
IP
traffic. The secondary AppleTalk
traffic Device C generates is also
grouped into
VLAN
2, since the
AppleTalk traffic does not match
any existing
VLAN
policy.
The result is that Devices A and
C are unable to communicate.
Creation of an AppleTalk proto-
col
VLAN
solves this problem.
If
a n A p p l e T a l k
V L A N
e x i s t s ,
Device A will be assigned to it
and removed from Default
VLAN
#1. Device C will be assigned to
both the
IP
VLAN
and the Apple-
Talk
VLAN
. Devices A and C can
then communicate.
