ProLiant BL p-Class GbE2 Interconnect Switch Application Guide

RSTP and MSTP 66
Link type
The link type determines how the port behaves in regard to Rapid Spanning Tree. The link type corresponds to
the duplex mode of the port. A full-duplex link is point-to-point (p2p), while a half-duplex link should be
configured as shared. If you select auto as the link type, the port dynamically configures the link type.
RSTP configuration guidelines
This section provides important information about configuring Rapid Spanning Tree Groups:
• When RSTP is turned on, STP parameters apply only to STP Group 1.
• Before RSTP is turned on, STP Groups 2-32 must be disabled and cleared.
RSTP configuration example
This section provides steps to configure Rapid Spanning Tree on the HP ProLiant BL p-Class GbE2 Interconnect
Switch, using the Command-Line Interface (CLI) or the Browser-Based Interface (BBI).
Configuring Rapid Spanning Tree (CLI example)
1. Configure port and VLAN membership on the switch, as described in the “Configuring Ports and VLANs
(CLI example)” section in the “VLANs” chapter of this guide.
2. Disable and clear STP groups 2 through 32.
>> /cfg/l2/stp 2 (Select Spanning Tree Group 2)
>> Spanning Tree Group 2# clear (Clear STP Group 2 parameters)
>> Spanning Tree Group 2# off (Turn off STP Group 2)
3. Set the Spanning Tree mode to Rapid Spanning Tree.
>> /cfg/l2/mrst (Select Multiple Spanning Tree menu)
>> Multiple Spanning Tree# mode rstp (Set mode to Rapid Spanning Tree)
>> Multiple Spanning Tree# on (Turn Rapid Spanning Tree on)
4. Configure STP Group 1 parameters.
>> /cfg/l2/stp 1 (Select Spanning Tree Protocol menu)
>> Spanning Tree Group 1# add 2 (Add VLAN 2 STP group 1)
>> Spanning Tree Group 1# apply (Apply the configurations)
Configuring Rapid Spanning Tree Protocol (BBI example)
1. Configure port and VLAN membership on HP ProLiant BL p-Class GbE2 Interconnect Switch A, as described
in the “Configuring Ports and VLANs (BBI example)” section in the “VLANs” chapter of this guide.
2. Disable and clear STP groups 2 through 32.
