Bridge RSTP/PVRST Configuration
Spanning Tree bridge parameters affect the global STG operation of the switch.
STG bridge parameters include:

Bridge priority

Bridge hello time

Bridge maximum age

Forwarding delay
When configuring STG bridge parameters, the following formulas must be used:
 2 × ( forwarding delay ‐ 1) > bridge maximum age
 2 × ( bridge hello time + 1) < bridge maximum age
Table 227.
Bridge Spanning Tree Configuration Options
Command Syntax and Usage
spanning ­ tree stp
<1 ‐ 128>
bridge forward ­ delay
<4 ‐ 30>
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 discarding and learning states to the forwarding state.
The range is 4 to 30 seconds and the default is
15
seconds.
Note: This command does not apply to MSTP.
Command mode: Global configuration
no spanning ­ tree stp
<1 ‐ 128>
bridge forward ­ delay
Resets the bridge forward delay parameter to its default value of
15
seconds.
Command mode: Global configuration
spanning ­ tree stp
<1 ‐ 128>
bridge hello ­ time
<1 ‐ 10>
Configures the bridge Hello time.The Hello time specifies how often the
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.
Note: This command does not apply to MSTP.
Command mode: Global configuration
no spanning ­ tree stp
<1 ‐ 128>
bridge hello ­ time
Resets the birdge Hello time to its default value of
2
seconds.
Command mode: Global configuration
spanning ­ tree stp
<1 ‐ 128>
bridge maximum ­ age
<6 ‐ 40>
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.
Note: This command does not apply to MSTP.
