addresses will override the modules “IP Address” and “Subnet Mask” and the Device Mode will be changed to
“VLAN Bridge.” These changes will be indicated on the Network page of the module. A Management VLAN is
created to ensure that the module will be accessible for configuration and diagnostics after setup.
If more than one interface is added to a VLAN group, a separate bridge will be created for the VLAN group. The
configured interfaces for the VLAN group will then be configured as ports on the bridge.
In Figure 68, the Management VLAN has two interfaces configured, Ethernet and Wireless, and both are set to
“Untagged.” This means the module can be accessed by either Ethernet or Wireless networks using untagged
frames.
Figure 68 VLAN Aware
NOTE Leaving the default Management VLAN is advised, as it will ensure that the module is accessible
through any interface.
VLAN Group
Enabling VLAN Aware 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 four priority radio queues VLAN tagged frames will be queued on
when transmitted via the radio.
