Configuration Menu 117
The following table describes the commands used to configure CIST Port Configuration Menu options.
Table 117 CIST Port Configuration Menu options
Command Description
prior <0-240> Configures the CIST port priority. The port priority helps determine which bridge port
becomes the designated port. In a network topology that has multiple bridge ports
connected to a single segment, the port with the lowest port priority becomes the
designated port for the segment. The range is 0 to 240, in steps of 16 (0, 16, 32...),
and the default is 128.
cost <1-200000000> Configures the CIST port path cost. The port path cost is used to help determine the
designated port for a segment. Generally speaking, the faster the port, the lower the
path cost. The default is 20000 for Gigabit ports.
hello <1-10> Configures the CIST port Hello time. The Hello time specifies how often the root bridge
transmits a configuration bridge protocol data unit (BPDU). Any bridge that is not the
root bridge uses the root bridge Hello value. The range is 1 to 10 seconds, and the
default is 2 seconds.
link auto|p2p|shared Defines the type of link connected to the port, as follows:
auto: Configures the port to detect the link type, and automatically match its settings.
p2p: Configures the port for Point-To-Point protocol.
shared: Configures the port to connect to a shared medium (usually a hub).
The default link type is auto.
edge disable|enable Enables or disables this port as an edge port. An edge port is not connected to a
bridge, and can begin forwarding traffic as soon as the link is up. Configure server
ports as edge ports (enabled). This command is disabled by default.
on Enables CIST on the port.
off Disables CIST on the port.
cur Displays the current CIST port configuration.
Spanning Tree configuration
Command: /cfg/l2/stp
[Spanning Tree Group 1 Menu]
brg - Bridge parameter menu
port - Port parameter menu
add - Add VLAN(s) to Spanning Tree Group
remove - Remove VLAN(s) from Spanning Tree Group
clear - Remove all VLANs from Spanning Tree Group
on - Globally turn Spanning Tree ON
off - Globally turn Spanning Tree OFF
default - Default Spanning Tree and Member parameters
cur - Display current bridge parameters
HP ProLiant BL p-Class GbE2 Interconnect Switch supports the IEEE 802.1d Spanning Tree Protocol (STP) and Cisco
proprietary PVST and PVST+ protocols. STP is used to prevent loops in the network topology. You can configure up to
32 spanning tree groups on the switch. This command is turned on by default.
NOTE: When RSTP is turned on, only STP group 1 can be configured.
The following table describes the Spanning Tree Configuration Menu options.
Table 118 Spanning Tree Configuration Menu options
Command Description
brg Displays the Bridge Spanning Tree Menu.
port <port number> Displays the Spanning Tree Port Menu.
add <1-4095> Associates a VLAN with a spanning tree and requires an external VLAN ID as a
parameter.
