Description
Configures the bridge priority. The bridge
priority parameter controls which bridge on the
network is the STP root bridge.
To make this GbE2 Interconnect Switch the root
bridge, configure the bridge priority lower than
all other GbE2 Interconnect Switches and
bridges on your network. The lower the value,
the higher the bridge priority. The range is 0 to
65535, and the default is 32768.
Configures the bridge hello time. The hello time
specifies how often the root bridge transmits a
configuration bridge protocol data unit (BPDU).
Any bridge that is not the root bridge uses the
root bridge hello value. The range is 1 to 10
seconds, and the default is 2 seconds.
Configures the bridge maximum age. The
maximum age parameter specifies the
maximum time the bridge waits without
receiving a configuration bridge protocol data
unit before it reconfigures the STP network.
The range is 6 to 40 seconds, and the default is
20 seconds.
Configures the bridge forward delay parameter.
The forward delay parameter specifies the
amount of time that a bridge port has to wait
before it changes from the listening state to the
learning state and from the learning state to the
forwarding state. The range is 4 to 30 seconds,
and the default is 15 seconds.
Configures the Forwarding Database aging
time. The aging time specifies the amount of
time the bridge waits without receiving a packet
from a station before removing the station from
the forwarding database. The range is 1 to
65535 seconds, and the default is 300 seconds.
To disable aging, set this parameter to zero (0).
Displays the current bridge STP parameters.
