Configurations - HP Cluster Platform Express v2010 Overview

C Configuring a VLAN for the Administrative Network for
c3000 BladeSystem Configurations
If a c3000-based configuration is connected to an external network, both the
Administrative/Console network and the external network are connected to the same switch.
Although IP addressing and subnetting may be used to separate these networks, the default
settings of the HP GbE2C Ethernet switch will transmit broadcast traffic between the
Administrative/Console network and the external network.
To control this and to allow separate management policies to be applied to the
Administrative/Console network from the external network, it is possible to create a VLAN for
the Administrative/Console network. The VLAN must have as its members the internal ports of
the HP GbE2C Ethernet switch that are connected to NIC1 of the servers (ports 1-8 on the switch)
and the switches management interface. By default, all ports are members of VLAN1.
Enter the following HP GbE2C Ethernet switch CLI commands to create a second VLAN. Name
VLAN 2 "AdminNet" and add the switch ports to it. The CLI prompts (of the form >> level) are
as follows:
>> /cfg/l2/vlan 2
>> VLAN 2 Name AdminNet
>> VLAN 2 add 1
>> VLAN 2 add 2
>> VLAN 2 add 3
>> VLAN 2 add 4
>> VLAN 2 add 5
>> VLAN 2 add 6
>> VLAN 2 add 7
>> VLAN 2 add 8
>> VLAN 2 ena
Assuming that the switch ssh or telnet management interface address has been assigned to IP
interface "if 1", add that to the VLAN with the following commands:
>> VLAN 2 /cfg/l3/if 1
>> IP Interface 1 # vlan 2
Return to the top menu (enter "/" at the current CLI prompt), apply, and save the configuration,
as follows:
>> apply
>> save
