Static IPv4 parameters can not be set when the IPv4 configuration method is set to DHCP.	`ifconfig -c` config_method where config_method is `dhcp` `static` `dthens` This command can only be run by users who have one or more of the following command authorities: Supervisor I/O module configuration See Commands and user authority for additional information.	I/O module: switch[x] where x is the I/O-bay number.
Set starting IP address for I/O module (IPv4)	Sets the IPv4 IP addresses for the specified I/O module. Note Static IPv4 parameters can not be set when the IPv4 configuration method is set to DHCP.	`ifconfig -i` ip_address where ip_address is the IP address of the specified I/O module in dotted decimal IP address format. This command can only be run by users who have one or more of the following command authorities: Supervisor I/O module configuration See Commands and user authority for additional information.	I/O module: switch[x] where x is the I/O-bay number.
Set starting IP address for I/O module (IPv6)	Sets the IPv6 static IP address for the specified I/O module.	`ifconfig -i6` ip_address where ip_address is the static IP address for the specified I/O module in IPv6 format. This command can only be run by users who have one or more of the following command authorities: Supervisor I/O module configuration See Commands and user authority for additional information.	I/O module: switch[x] where x is the I/O-bay number.

I/O module: switch[x] where x is the I/O-bay number.
Keep new IP address configuration for I/O-module after reset	Retains a new IP address configuration after the specified I/O module is reset. Note Make sure a valid New Static IP Configuration is entered for this I/O module so that when the module's manufacturing defaults are restored, or when a reset is initiated by a source other than the CMM, the New Static IP Configuration will be configured. In these cases CMM communication with the I/O module will be preserved.	`ifconfig -pip enabled` This command can only be run by users who have one or more of the following command authorities: Supervisor I/O module administration I/O module configuration See Commands and user authority for additional information.	I/O module: switch[x] where x is the I/O-bay number.

Note The manufacturing default IP configuration will become active when the I/O module is reset to manufacturing defaults by either the CMM or the I/O module. If an I/O module reset is initiated by a source other than the CMM, then the previous IP configuration will be in affect. In both of these cases the CMM will lose IP communications with the I/O module.	`ifconfig -pip disabled` This command can only be run by users who have one or more of the following command authorities: Supervisor I/O module administration I/O module configuration See Commands and user authority for additional information.	I/O module: switch[x] where x is the I/O-bay number.

Example:

To set the CMM IPv4 static IP address for Ethernet channel 0 to 192.168.70.133, while the Lenovo Flex System chassis is set as the persistent command environment, at the system> prompt, type

ifconfig -eth0 -i 192.168.70.133 -c static -T mm[p]

The following example shows the information that is returned from this command:

system> ifconfig -eth0 -i 192.168.70.133 -c static -T mm[p]
<span className="ph">Changes to -c, -i, -s, -g, and -f will become active after the next reset of the 
CMM, or by using the -apply flag.</span>
system>

To display the configuration for CMM Ethernet channel 0, after the above change has been applied, while the Lenovo Flex System chassis is set as the persistent command environment, at the system> prompt, type

ifconfig -eth0 -T mm[p]

The following example shows the information that is returned from this command:

system> ifconfig -eth0 -T mm[p]
