BreezeNET BU-DS.11/RB-DS.11 C-5 User’s Guide
The BU-DS.11/RB-DS.11 DS.11 comes with a graphical management utility that
operates on any Windows based network ready PC. With this utility you can configure
and monitor every DS.11 on your network. You can also use the DS.11 SNMP MIB on
standard management platforms like SNMPc, and HP Openview.
Does the DS.11 offer out-of-band management?
No, the DS.11 does not offer out-of-band management, such as a serial port. The
DS.11 is managed in-band only via the DS.11 manager utility or SNMP.
Can I use the AMP250 or AMP500 on the DS.11?
No. The AMP250/500 products are not tested or certified for use with the DS.11
products.
What installation and site survey tools are available for BU-DS.11/RB-DS.11?
The DS.11 comes with a Windows based manager utility. With this utility you can
configure link parameters and monitor signal quality and RSSI (received signal
strength indication). Optimizing antenna alignment is done using the signal quality and
RSSI display. Any computer on the network can use this utility to manage the BU-
DS.11/RB-DS.11.
Is the DS.11 compatible with other DS equipment from other vendors?
Yes. However, for the outdoor bridges, interoperability can vary from vendor to
vendor, and in some cases it may not operate if the manufacturer’s implementation is
not pure 802.11. The BU-DS.11/RB-DS.11 can operate at 1 and 2Mbps with legacy
802.11 DS equipment, and at 5.5Mbps and 11Mbps with 802.11b High Rate DS
equipment.
Does the BU-DS.11/RB-DS.11 DS.11 support 802.1d spanning tree protocol?
No, the BU-DS.11/RB-DS.11 does not support spanning tree. This is because the BU-
DS.11 can also support roaming devices.
What is the normal PER (packet error rate) for the BU-DS.11/RB-DS.11?
The error rate will be about 4%-6% (transmitted fragments vs. retry count). This is
typical when operating in a non-interference environment at maximum range for bi-
directional traffic loads. If the traffic load is more uni-directional, then the PER will
be less.
What is the best value for the CW win parameter on the DS.11?
