Chapter 4 Configuring Radio Settings
Configuring the Radio Distance Setting
Configuring the Radio Distance Setting
Use the distance command to specify the distance from a root bridge to its clients (non-root bridges
and/or workgroup bridges). The distance setting adjusts the time out values to account for the time
required for radio signals for radio signals to travel from a root bridge to its clients (non-root bridges
and/or workgroup bridges). If more than one non-root bridge (or workgroup bridge) communicates with
the root bridge, enter the distance from the root bridge to the non-root bridge (or work-group bridge) that
is farthest away. Enter a value from 0 to 99 km for a 2.4-GHz WMIC or 0 to 3 km for a 4.9-GHz WMIC.
You do not need to adjust this setting on non-root bridges.
In installation mode, the default distance setting is 99 km. In other modes, the default distance setting is
0km.
Beginning in privileged EXEC mode, follow these steps to configure the distance setting:
Use the no form of the distance command to set the default distance.
Enabling and Disabling Reliable Multicast to Workgroup
Bridges
The Reliable multicast messages from the access point to workgroup bridges setting limits reliable
delivery of multicast messages to approximately 20 Cisco Workgroup Bridges that are associated to the
access point. The default setting, disabled, reduces the reliability of multicast delivery to allow more
workgroup bridges to associate to the access point.
Access points and bridges normally treat workgroup bridges not as client devices but as infrastructure
devices, like access points or bridges. Treating a workgroup bridge as an infrastructure device means that
the access point reliably delivers multicast packets, including Address Resolution Protocol (ARP)
packets, to the workgroup bridge.
The performance cost of reliable multicast delivery—duplication of each multicast packet sent to each
workgroup bridge—limits the number of infrastructure devices, including workgroup bridges, that can
associate to the access point. To increase beyond 20 the number of workgroup bridges that can maintain
Step 3
concatenation bytes (Optional) Bytes specifies a maximum size for concatenation
packets in bytes. Enter a value from 1600 to 4000.
