VLANs According to IEEE 802.1Q with SLES9

Knowledgebase

Concern

You want to set up a VLAN in SUSE LINUX Enterprise Server 9 (SLES9) according to the standard IEEE 802.1Q.

Procedure

Create a configuration file for each VLAN:

 /etc/sysconfig/network/ifcfg-vlan?

Replace the question mark with the VLAN's number in increasing order, e.g. ifcfg-vlan1. Using ifcfg-vlan2 is not possible unless ifcfg-vlan1 has been previously configured. Insert the following options in the configuration file:

 ETHERDEVICE=eth0
 IPADDR=192.168.0.1
 NETMASK=255.255.255.0
 NETWORK=192.168.0.0
 BROADCAST=192.168.0.255
 STARTMODE=onboot

Adjust these options according to your needs. The option ETHERDEVICE must contain the Ethernet device used by the VLAN. Its value can be entered both in human-readable (eth0, eth1 etc.) and machine-readable form (e.g. eth-id-00:30:6e:4c:20:9c). Finally, execute rcnetwork restart. Your VLAN should now be available.

For additional information refer to the vconfig man pages and the section "Virtual LANs (802.1q)" in ifup man pages.
