802.1w Rapid Spanning Tree Protocol (RSTP) 802.1d Spanning Tree Protocol (STP)

 

Configuring Rapid Reconfiguration Spanning Tree (RSTP)

 

 

N o t e

Executing the spanning-treecommand 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 14, 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.

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:

HPswitch (config)# span max 30 hello 3k
