wEb-bASED bROwSER MANAGEMENT
frame transfer. In a network of RSTP bridges, the time spent in this state is usually
quite short. RSTP bridges operating in STP compatibility mode will spend 6 to 40
seconds in this state.
After learning, the bridge will place the port in the forwarding state. The port both
learns addresses and participates in frame transfer while in this state.
From here, you can congure the RSTP.
System Priority: Options range from “0” to “61440.” Default: 32768. This setting
provides a way to control the topology of the STP-connected network. The desired
root and designated bridges can be congured for a particular topology. The
bridge with the lowest priority will become root. In the event of a failure of the
root bridge, the bridge with the next-lowest priority will then become root.
Designated bridges that (for redundancy purposes) service a common LAN also
use priority to determine which bridge is active. In this way, careful selection of
System Priorities can establish the path of trafc ows in normal and abnormal
conditions.
Hello Time: Enter a value from 1 to 10. Default: 2. This is the time between
conguration messages issued by the root bridge. Shorter hello times result in
faster detection of topology changes at the expense of moderate increases in
STP trafc.
Max Age: Enter a value from 6 to 40. Default: 20. This is the time for which a
conguration message remains valid after being issued by the root bridge.
Congure this parameter with care when many tiers of bridges exist or when
slow speed links (such as those used in WANs) are part of the network.
Forward Delay: Enter a value from 4 to 30. Default: 15. This is the amount of time
a bridge spends learning MAC addresses on a rising port before beginning to
forward trafc. Lower values allow the port to reach the forwarding state more
quickly, but at the expense of ooding unlearned addresses to all ports.
Force Version: Either “Normal” (default) or “Compatible.” Select the version of
