Spanning-Tree Operation 
Configuring Rapid Reconfiguration Spanning Tree (RSTP) 
Note   Executing the spanning-tree command alone enables spanning tree. Executing 
the command with one or more of the whole-switch RSTP parameters shown 
in the table on the previous page, or with any of the per-port RSTP parameters 
shown in the table on page 18, does not enable spanning tree. It only configures 
the spanning tree parameters, regardless of whether spanning tree is actually 
running (enabled) on the switch. 
Using this facility, you can completely configure spanning tree the way you 
want and then enable it. This method minimizes the impact on the network 
operation. 
Syntax:   Abbreviations: 
spanning-tree 
span 
protocol-version <rstp | stp> 
prot <rstp | stp> 
force-version <rstp-operation | stp-compatible> 
forc <rstp | stp> 
priority <0 - 15> 
pri <0 - 15> 
maximum-age <6 - 40 seconds> 
max <6 - 40> 
hello-time <1- 10 seconds> 
hello <1 - 10> 
forward-delay <4 - 30 seconds> 
forw <4 - 30> 
Defaults: See the table on the previous page. 
Multiple parameters can be included on the same command line. For example, 
to configure a maximum-age of 30 seconds and a hello-time of 3 seconds, you 
would issue the following command: 
ProCurve (config)# span max 30 hello 3
