During installation and configuration of the SUSE Linux Enterprise Server OS, you reach a point where you must enter the logical and physical names (MAC addresses) of the network interfaces.
This section explains how to launch a user shell during the SUSE Linux OS configuration to obtain the logical and physical network interface names that you need to continue with the configuration.
Before You Begin
Find and record the MAC addresses of all the physical ports from their labels.
The message Loading Linux Kernel appears followed by the SUSE splash screen, and then the Choose a Keyboard Map screen appears.
The user shell launches, and the Rescue Login prompt appears.
The Rescue prompt appears.
# ifconfig -a
The output of the Linux SUSE named and physical named network interfaces appear. Each interface found will list output similar to the following example:
eth0 Link encap:Ethernet HWaddr 00:14:4F:8D:52:BE inet addr:10.182.92.196 Bcast:10.182.93.255 Mask:255.255.254.0 inet6 addr: fe80::214:4fff:fe8d:52be/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:14463420 errors:0 dropped:0 overruns:0 frame:0 TX packets:1061441 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1282809896 (1.1 GiB) TX bytes:118848836 (113.3 MiB) Interrupt:54 Base address:0xc000 eth1 Link encap:Ethernet HWaddr 00:14:4F:8D:52:BF BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:21 Base address:0x2000 eth2 Link encap:Ethernet HWaddr 00:14:4F:8D:52:C0 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:44 Base address:0x6000 eth3 Link encap:Ethernet HWaddr 00:14:4F:8D:52:C1 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:47 Base address:0xa000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:44421 errors:0 dropped:0 overruns:0 frame:0 TX packets:44421 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:4976408 (4.7 MiB) TX bytes:4976408 (4.7 MiB)
The eth0 entry in the first column is the logical name of the Ethernet interface assigned by the operating system. The lo entry in the first column is the loopback interface.
The HWaddr 00:14:4F:8D:52:BE entry in second column (first row) is the physical MAC address of the network port.
If you have multiple network interfaces and the output of interfaces scrolls off the top of the screen, you can display the output per interface.
# ifconfig eth#
where eth# is the interface number.
You will need to refer to this record when configuring the network interfaces during the Linux SUSE OS installation.
