28.1.5. Specifying the Network Settings
boot:prompt as follows:
- The system's IP address.
- The system's netmask.
- The IP address of the network gateway.
- The IP address of the DNS server.
- The network device to use with these settings.
- The name you wish to assign to the network device, followed by the device's MAC address.
- The virtual LAN ID number (802.1q tag) for the specified network device.
- The delay after which the network will be considered active. If you use this option, the system will wait after bringing up network interfaces until either the gateway is successfully pinged, or until the amount of seconds specified in this parameter passes. This is useful for some NICs which may report that a link is available before it actually is, causing any operations which require network access (such as Kickstart file downloads) to fail. Maximum value of this parameter is 30 as defined by NetworkManager; specifying a value higher than 30 will cause the option to be ignored.
eth0. The interface is named
primary, and the system will wait for 5 seconds or until it can successfully ping the gateway before continuing:
linux ip=192.168.1.10 netmask=255.255.255.0 gateway=192.168.1.1 dns=192.168.1.3 ksdevice=eth0 ifname=primary:01:23:45:67:89:ab nicdelay=5
