Filter Aging Time
Base Stations maintain dynamic lists to identify the interface where they last spotted
a BreezeNET station (either the Ethernet interface, or BreezeNET interface A or B).
When the Base Station receives a packet addressed to a specific station, this list will
help to determine to which interface the packet should be bridged.
When mobile stations roam between multiple cells this table will be updated
automatically.
When there is no traffic from or to a specific station for a longer period of time (for
example when a station was shut down), the Filter Aging Time determines how long
the access point will ‘remember’ the location of this BreezeNET device.
Firmware
Basic operating software for BreezeNET PC Card and Base Station that is factory-
installed.
Occasionally firmware upgrades may become available when new functions or
features are developed for your BreezeNET product.
Firmware Upgrade
Upgrade for the embedded software on the hardware of your BreezeNET product.
! For BreezeNET PC Card, firmware upgrades are distributed as an executable
file of the format “wsuVVxxx.exe”, where “xxx” identifies the version of the
upgrade. This executable file is run once on the computer containing the
PC Card.
! For Base Station, firmware upgrades are distributed as a binary file of the
format “wp2_vxxx.bin”, (where “xxx” identifies the version of the firmware. To
upgrade the firmware of the Base Station, use the
Upload Software option of the
Access Point menu of your AP Manager program.
Forward Delay
A timer for the ‘Spanning Tree Algorithm’ that prevents a bridge to forward data
packets when:
• he bridge receives information that the active Spanning Tree topology must be updated (for
example when a bridge breaks down or when somebody modified the ‘Bridge Priority’ or ‘Path
Cost’ value of a particular bridge);
• the bridge registers that the protocol information exceeds the specified ‘Max. Age’ value.
Changes in the Spanning Tree topology must be communicated to all bridges in the
bridged network. The Forward Delay timer will compensate for the propagation
delays that occur in passing the protocol information, allowing all bridges to close
the old data paths, before the new data paths are activated.
Recommended value: 15 seconds
H
Hello Time
A Spanning Tree parameter that identifies the time interval between Configuration
BPDU messages as transmitted by a root bridge or a bridge that is attempting to
become the root bridge.
Recommended value: 2 seconds.
