Some situations require Exalt radios to act upon VLAN traffic and perform any or all of the following
functions:
• Connect specific traffic, using VLAN tagging, to different purposes, such as management traffic to
the radio’s NMS system.
• Allow only traffic with specifically assigned VLANs to pass across the link, blocking all other
VLANs or any non-VLAN traffic.
• Allow management access only through a VLAN connection, leaving the main traffic transparent.
• Allow management access without a VLAN connection, but flowing only specific VLAN traffic
across the link.
Link Symmetry
The default configuration of ExtendAir
®
(TDD) Series Direct Mount radios provides 50/50
symmetrical throughput. The Tx/Rx Throughput Ratio setting enables programming different
symmetry for applications where significantly higher throughput in one direction is anticipated such as
for video broadcast, video aggregation, or remote server/storage WANs.
Exalt does not recommend placing two links with asymmetry back-to-back in a serial configuration
due to the TDD cycle of the radios. This configuration requires that one radio transmits in an
overlapping time period while another radio is receiving. Physical antenna isolation and/or frequency
channel spacing may accommodate this configuration. Asymmetry is, however, ideal for single-hop,
multi-link hub/spoke architectures, or simply single independent links.
TDD frame sizes of 2ms and 5ms are supported. The 5ms configuration maximizes the aggregate
throughput of the radio for every situation. The 2ms configuration reduces latency to meet latency-
critical applications, especially for multi-link and TDM circuit support. The following RF BW/mode
combinations are supported for these two configurations:
• 16MHz/Mode1
• 16MHz/Mode2
• 16MHz/Mode 3
• 32MHz/Mode1
• 32MHz/Mode2
• 32MHz/Mode 3
The following Tx/Rx ratios are supported for these two configurations:
• 65/35 and 35/65
• 80/20 and 20/80
Note: If an application only requires the transparent passing of VLAN traffic, disable the VLAN
function.
Note: Asymmetry is only supported for a specific subset of system configurations that are
optimized for typical asymmetric applications.
Note: The 80/20 configuration is not supported for 32MHz/Mode3, because the capacity of
the 100BaseT interface is fully utilized at 65/35 configuration for this setting.
