Spanning-Tree Operation
802.1s Multiple Spanning Tree Protocol (MSTP)
N o t e
6-58
Syntax: spanning-tree-protocol-version mstp
Changes the current spanning-tree protocol on the switch to
802.1s Multiple Spanning Tree. Must be followed by write mem
and reboot to activate the change. After rebooting, the switch
is ready to operate as an MSTP bridge. Note that this command
does not enable spanning-tree operation. To activate the
configured spanning-tree operation on the switch, execute
spanning-tree.
Note: When you activate spanning-tree operation or change
the spanning-tree configuration while spanning tree is
enabled, the switch must recalculate the network paths it
uses.To minimize traffic delays while this convergence occurs,
HP recommends that you not activate spanning tree operation
until you have finished configuring all devices in your
network. Refer to "Enabling an Entire MST Region at Once or
Exchanging One Region Configuration for Another" on
page 6-69.
The following commands are available only when the switch is configured for
MSTP protocol operation.
Syntax: [no] spanning-tree config-name < ascii-string >
This command resets the configuration name of the MST
region in which the switch resides. This name can include up
to 32 nonblank characters and is case-sensitive. On all
switches within a given MST region, the configuration names
must be identical. Thus, if you want more than one MSTP
switch in the same MST region, you must configure the
identical region name on all such switches. If you retain the
default configuration name on a switch, it cannot exist in the
same MST region with another switch. (Default Name: A text
string using the hexadecimal representation of the switch's
MAC address)
The no form of the command overwrites the currently
configured name with the default name.
Note: This option is available only when the switch is
configured for MSTP operation. Also, there is no defined
limit on the number of regions you can configure.
