SD Series Technical Manual
MDS 05-4846A01, Rev. H
When the Wireless or Ethernet port (AP or Remote) is configured as an
Access Port, the radio tags incoming traffic with a VLAN ID, and strips
the tag before sending out traffic. This traffic is known as the Data
VLAN. Additionally, a
second
VLAN is assigned for other traffic that
is terminated at the radio, such as Web, Telnet, DLINK over TCP, TFTP
reprogramming, etc. This traffic is known as the Management VLAN.
Traffic directed to the terminal server or IP payload service should be
sent via the Data VLAN.
When the Ethernet port of a Remote is configured as a VLAN trunk, the
radio expects all incoming Ethernet frames to be tagged, and passes
through all outgoing frames as received from the wireless link with the
unchanged VLAN tag.
•
Mode
—Defines the Ethernet port as
Trunk
,
Access
, or
Disable
(an
untagged port). The default setting is
Disable
.
The mode should be
the last parameter changed when configuring the VLAN fea-
ture, since any Telnet or web connections will be lost after it
is changed.
Also, configure the appropriate IP and IP2 settings
before changing this parameter.
•
Data ID
—Defines the VLAN ID assigned to the AP’s LAN traffic
to be delivered to an Access Port, and the terminal server service,
or the IP payload service. The ID is used for filtering and tagging
purposes. Any valid ID from 1 to 4095 may be entered. The
Default Data VLAN ID is
2
.
•
Mgmt ID
—Defines the VLAN ID assigned to the AP’s LAN traffic
that is to be delivered to the radio. Note that traffic for the termi-
nal server and IP payload service is expected in the data VLAN.
This ID is used for filtering and tagging purposes. Any valid ID
from 1 to 4095 may be entered. The Default Mgmt VLAN ID is
1
.
•
Gateway IF
—Defines the VLAN that contains the default gateway
in the radio. Available selections are
Mgmt
and
Data
. The default
setting is
Mgmt
.
NOTE:
The
VLAN Mode
parameter must be consistent at both the AP
and Remote radios in order for data to flow correctly. Failure
to do so may result in data not being transported correctly even
when the radios are able to communicate over-the-air via an
RF link.
