Configuring Spanning Tree Protocol (STP) and Advanced STP Features
NOTE: If the device has only one port-based VLAN (the default VLAN), then the device is already running a
single instance of STP. In this case, you do not need to enable SSTP. You need to enable SSTP only if the device
contains more than one port-based VLAN and you want all the ports to be in the same STP broadcast domain.
USING THE CLI
To configure the HP device to run a single spanning tree, enter the following command at the global CONFIG
level.
HP9300(config)# spanning-tree single
NOTE: If the device has only one port-based VLAN, the CLI command for enabling SSTP is not listed in the CLI.
The command is listed only if you have configured a port-based VLAN.
To change a global STP parameter, enter a command such as the following at the global CONFIG level:
HP9300(config) spanning-tree single priority 2
This command changes the STP priority for all ports to 2.
To change an STP parameter for a specific port, enter commands such as the following:
HP9300(config) spanning-tree single ethernet 1/1 priority 10
The commands shown above override the global setting for STP priority and set the priority to 10 for port 1/1.
Here is the syntax for the global STP parameters.
Syntax: [no] spanning-tree single [forward-delay <value>]
[hello-time <value>] | [maximum-age <time>] | [priority <value>]
Here is the syntax for the STP port parameters.
Syntax: [no] spanning-tree single [ethernet <portnum> path-cost <value> | priority <value>]
NOTE: Both commands listed above are entered at the global CONFIG level.
USING THE WEB MANAGEMENT INTERFACE
1. Log on to the device using a valid user name and password for read-write access.
2. Click the Single checkbox next to Spanning Tree to place a checkmark in the box.
3. Make sure Enable, not Disable, is selected next to Spanning Tree.
4. Click Apply to apply the change to the device's running-config.
5. Select the Save link at the bottom of the panel. Select Yes when prompted to save the configuration change
to the startup-config file on the device's flash memory.
Displaying SSTP information
To verify that SSTP is in effect, enter the following commands at any level of the CLI:
HP9300(config)# show span
Syntax: show span [vlan <vlan-id>] | [pvst-mode] | [<num>] |
[detail [vlan <vlan-id> [ ethernet <portnum> ] | <num>]]
The vlan <vlan-id> parameter displays STP information for the specified port-based VLAN.
The pvst-mode parameter displays STP information for the device's Per VLAN Spanning Tree (PVST+)
compatibility configuration. See "PVST/PVST+ Compatibility" on page 8-75.
The <num> parameter displays only the entries after the number you specify. For example, on a device with three
port-based VLANs, if you enter 1, then information for the second and third VLANs is displayed, but information for
the first VLAN is not displayed. Information is displayed according to VLAN number, in ascending order. The
entry number is not the same as the VLAN number. For example, if you have port-based VLANs 1, 10, and 2024,
