 Bridge hello time
 Bridge maximum age
 Forwarding delay

Command Syntax and Usage
prior <new bridge priority (0-65535)>
Configures the bridge priority. The bridge priority parameter controls which bridge on the
network is the STG root bridge. To make this switch the root bridge, configure the bridge
priority lower than all other switches and bridges on your network. The lower the value, the
higher the bridge priority. The default value is 32768.
hello <new bridge hello time (1-10 secs)>
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.
This command does not apply to MSTP (see CIST on page 224).
mxage <new bridge max age (6-40 secs)>
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 re
configures the STG network. The range is 6 to 40 seconds, and the default is 20 seconds.
This command does not apply to MSTP (see CIST on page 224).
