Step 2
Enter the following command:
boot networkconfig { dhcp | { { dhcp-static-fallback | static } ip address spio24
ip_address24 [ spio25 ip_address25 ] netmask subnet_mask [ gateway gw_ip_address
] } }
ip_address24 [ spio25 ip_address25 ] netmask subnet_mask [ gateway gw_ip_address
] } }
For complete information about the above command, see the Global Configuration Mode Commands chapter of the
Command Line Interface Reference.
Command Line Interface Reference.
The following command configures the boot network to communicate using DHCP, with a static-fallback IP address for
SPIO in slot 24 of 192.168.206.101 and a Class C netmask.
SPIO in slot 24 of 192.168.206.101 and a Class C netmask.
boot networkconfig dhcp-static-fallback ip address spio24 192.168.206.101 netmask
255.255.255.0
255.255.255.0
The next example uses static IP addresses for SPIOs in both slots 24 and 25, which can access the external network
server through a gateway whose IP address is 135.212.10.2.
server through a gateway whose IP address is 135.212.10.2.
boot networkconfig static ip address spio24 192.168.206.101 spio25
192.168.206.102 netmask 255.255.255.0 gateway 135.212.10.2
192.168.206.102 netmask 255.255.255.0 gateway 135.212.10.2
Step 3
Save the configuration as described in the Verifying and Saving Your Configuration chapter.
Configuring Boot Network Delay Time
An optional delay period, in seconds, can be configured for systems booting from a network. The purpose of this
parameter is to allow time for external devices, such as switches, that use the Spanning Tree Protocol (STP) to
determine the network route to a specified IP address.
parameter is to allow time for external devices, such as switches, that use the Spanning Tree Protocol (STP) to
determine the network route to a specified IP address.
To configure a boot network delay, enter the following command from the Global Configuration mode prompt.
boot delay time
Where time is an integer from 1 to 300 seconds before attempting to contact the external network server. If your
network uses STP, a typical delay time of 30 seconds should suffice.
network uses STP, a typical delay time of 30 seconds should suffice.
Important:
Save your configuration as described in the Verifying and Saving Your Configuration chapter.
Configuring a Boot Nameserver
To enter the hostname of the network server that hosts the operating system software image, first configure the IP
address of the Domain Name Service (DNS) server, referred to as a name server, that can resolve the host name for the
machine.
address of the Domain Name Service (DNS) server, referred to as a name server, that can resolve the host name for the
machine.
To configure a boot nameserver address, enter the following command from the Global Configuration mode prompt.
boot nameserver ip_address
Where ip_address is the IP address of the DNS server entered in IPv4 dotted-decimal notation.
