VLAN Transparent This feature determines how a mesh access point handles
VLAN tags for Ethernet bridged traffic.
Note Refer to the “Configuring Advanced Features”
section on page 97 for overview and additional
configuration details.
If VLAN Transparent is enabled, then VLAN tags are not
handled and packets are bridged as untagged packets.
Note No configuration of Ethernet ports is required
when VLAN transparent is enabled. The Ethernet
port passes both tagged and untagged frames
without interpreting the frames.
If VLAN Transparent is disabled, then all packets are
handled according to the VLAN configuration on the port
(trunk, access, or normal mode).
Note If the Ethernet port is set to Trunk mode, then
Ethernet VLAN tagging must be configured. Refer
to “Using the GUI to Enable Ethernet Bridging”
section on page 78.
Note For an overview of normal, access, and trunk
Ethernet port use, refer to the “Ethernet Port Notes”
section on page 99.
Note To use VLAN tagging, you must uncheck the
VLAN Transparent check box.
Note VLAN Transparent is enabled as a default to ensure
a smooth software upgrade from 4.1.192.xxM
releases to release 5.2. Release 4.1.192.xxM does
not support VLAN tagging (see Figure 44).
Default: Enabled.
Security Mode Defines the security mode for mesh access points:
Pre-Shared Key (PSK) or Extensible Authentication
Protocol (EAP).
Note EAP must be selected if external MAC filter
authorization using a RADIUS server is
configured.
Note Local EAP or PSK authentication is performed
within the controller if the External MAC Filter
Authorization parameter is disabled (check box
unchecked).
Options: PSK or EAP
Default: EAP
