NOTE Leaving the default Management VLAN is advised, as it will ensure that the module is accessible
through any interface.
VLAN Group
Enabling VLAN on the module will require one or more configurable VLAN groups. A maximum of up to 10 VLAN
groups can be supported. Each VLAN group will contain the following configurable parameters and associated
functionality.
Name
A textual description of the VLAN group, consisting of a maximum of 32 ASCII
characters. This parameter is descriptive only and serves no functional purpose.
VLAN ID
A valid 12-bit IEEE802.1Q VID, with a range of 1–4095. The VLAN ID will be added
to all outgoing VLAN tagged frames for this VLAN group. All incoming VLAN tagged
frames for the VLAN group must have this VLAN ID.
VLAN Priority
An IEEE802.1Q-compatible, 3-bit Priority Code Point, with a range of 0–7, where
seven is the highest priority, one is the lowest, and zero is the default, which is a
mid-range “best-effort” value. The VLAN priority will be added to all outgoing VLAN
tagged frames for this VLAN group. Furthermore, the VLAN priority will be used to
determine which of 4 priority radio queues VLAN tagged frames will be queued on
when transmitted via the radio.
Management IP
The management IP is the address of the module if only one VLAN group is
configured. Access to the module’s internal Web based configuration and IP-based
functions (such as serial gateway, Modbus server) is provided via this management
IP address and subnet mask.
NOTE If only one VLAN group is configured, it must have a management IP
and netmask. If further VLAN groups are configured (groups 2–9), they
only need a Management IP and subnet if access to the modules IP-based
functions (such as Modbus or webpages) is required.
Management
Netmask
The IP network mask of the Management IP (see above).
Bridge STP
Turns on Spanning Tree Protocol (STP) for the bridge. STP prevents network loops
that can cause broadcast storms.
Bridge Priority
The STP priority number for the bridge. This value should be set in context with other
devices that are connected on the same network.
Interface Membership
Each VLAN group has a configurable interface membership list. The membership list will allow up to twelve possible
interfaces to be added. The following configurable parameters will apply to each entry.
Interface
Select an interface from the drop down list to be used for the VLAN group. Available
interfaces are, Ethernet, Wireless, or one of the 10 WDS Repeater connections that
correspond to configured entries on the Repeaters page.
Type
Specifies whether the interface is to support VLAN tagged or untagged frames. When
untagged is specified, all incoming frames on the interface must be untagged, and
all outgoing frames will be sent untagged. When tagged is specified, all incoming
frames must have a VLAN tag with VLAN ID matching the configured VLAN ID for the
VLAN group, and all outgoing frames on this interface will have a VLAN tag added
with the configured VLAN ID and priority for that VLAN group.
