The configuration and verification commands for the iSCSI feature are available when iSCSI is enabled on the switch. When you disable iSCSI, all associated configurations are automatically discarded. To use the CLI to enable iSCSI on a C-Series switch: 1. Enter configuration mode: switch # config terminal 2. Enable iSCSI on the switch: switch (config) # iscsi enable switch (config) # exit Enabling the iSCSI interface You must enable the iSCSI interface before traffic can flow on the GbE interface. To enable an iSCSI interface: 1. Create and enable the GbE interface: switch # config terminal switch (config) # interface gigabitethernet 2/1 switch (config-if) # no shutdown 2. Create and enable the iSCSI interface: switch (config-if) # exit switch (config) # interface iscsi 2/1 switch (config-if) # no shutdown Configuring the Gigabit Ethernet interface iSCSI uses TCP/IP for network connectivity. On each iSCSI-enabled C-Series switch, GbE interfaces provide connectivity. NOTE: GbE ports on any C-Series switch with the IP Storage Services Modules (IPS-4, IPS-8), Multi-protocol Services Module (14/2), or C-Series 9216i switch, should reside in a different Ethernet broadcast domain from the management Ethernet port. HP strongly recommends that you use separate standalone network hubs or switches, or separate VLANs, to configure the broadcast domains. To configure the IP interface for subsequent use by iSCSI Initiators: 1. Enter switch configuration mode: switch # config terminal 2. Enter interface configuration mode on the GbE interface: switch (config) # interface gigabitethernet 2/1 3. Enter the IP address (20.20.20.1) and subnet mask (255.255.255.0) for the GbE interface: switch (config-if) # ip address 20.20.20.1 255.255.255.0 4. Enable the interface: switch (config-if) # no shutdown switch (config-if) # exit switch (config) # exit 5. Complete steps 1 through 4 for both C-Series GbE ports. 32

1.
Create and enable the GbE interface:

switch (config-if) #

guring the Gigabit Ethernet interface
iSCSI uses TCP/IP for network connectivity. On each iSCSI-enabled C-Series switch, GbE interfaces
provide connectivity.
NOTE:
GbE ports on any C-Series switch with the IP Storage Services Modules (IPS-4, IPS-8), Multi–protocol
Services Module (14/2), or C-Series 9216i switch, should reside in a different Ethernet broadcast
domain from the management Ethernet port. HP strongly recommends that you use separate standalone
network hubs or switches, or separate VLANs, to con
fi
gure the broadcast domains.
To con
fi
gure the IP interface for subsequent use by iSCSI Initiators:
1.
Enter switch con
fi
guration mode:
switch #
con
fi
g terminal
2.
Enter interface con
fi
guration mode on the GbE interface:
switch (config) #
interface gigabitethernet 2/1
3.
Enter the IP address (20.20.20.1) and subnet mask (255.255.255.0) for the GbE interface:
switch (config-if) #
ip address 20.20.20.1 255.255.255.0
4.
Enable the interface:
switch (config-if) #
no shutdown
switch (config-if) #
exit
switch (config) #
exit
5.
Complete steps 1 through 4 for both C-Series GbE ports.
