 Bridge hello time
 Bridge maximum age
 Forwarding delay
 Bridge aging time

prior - Set bridge Priority [0-65535]
hello - Set bridge Hello Time [1-10 secs]
mxage - Set bridge Max Age (6-40 secs)
fwd - Set bridge Forward Delay (4-30 secs)

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 pri-
ority. The range is 0 to 65535, and the default is 32768.
RSTP/MSTP: The range is 0 to 61440, in steps of 4096 (0, 4096, 8192...), and the default
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 223).
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 223).
