Configure an Ethernet interface as a vlan trunk (Debian)

Vlan -devices are virtual Ethernet devices which represents the virtual lans on the physical lan.Error: trying to add vlan #1 to IF -:eth0:- error: Package not installed siocsifaddr: No such device eth0.1: error while getting interface flags: No such device siocsifnetmask: No such device eth0.1: error while getting interface flags: No such device Failed to bring up eth0.1.I suggest the following textbooks: A note about your LAN hardware.

# deviceeth0.5 bootprotonone onbootyes ipaddr. The kernel module should load automatically when you invoke ifup. Type the following commands # ip link set dev eth0.5 down # ip link delete eth0.5 How do I make above vlan configuration permanent on a Debian or Ubuntu based system? Device "eth0" does not exist. Use the ifconfig command to check that the interface exists. For more information, see interfaces(5). If a node from. Vlan works by tagging each frame.e.

Now open file using a text editor such as vi, type: # vi Find deviceeth0 line and replace with: deviceeth0.5 Also, append the following line: vlan yes Make sure you assign correct IP address using dhcp or static. To be able to use vlans you will need a switch that support the ieee 802.1q standard on an Ethernet network. Setting up 802.1q vlan tagging by loading 8021q Linux kernel driver First, make sure that the Linux kernel driver (module) called 8021q is loaded: # lsmod grep 8021q If the module is not loaded, load it with the following modprobe command: # modprobe 8021q Method. Suppose that a host requires access to two vlans, both carried by a trunk connected to physical interface eth0. Indicates that the vlan package (which provides the vconfig command) has not been installed. Only add gateway to /etc/sysconfig/network file. You are looking for one called 8021q (with no dot between 802 and 1q lsmod grep 8021q If the module is not listed then the most likely explanation is that it could not be found. d /sys/class/net/iface/brif/port ; then if -x /etc/network/if-pre-up. D/network restart OR # service network restart note: If you need a second vlan.e. To add vlan ID 5 with following command for eth0 interface : # vconfig add eth0 5 The vconfig add command creates a vlan -device on eth0 which result into eth0.5 interface. I will describe here in a form of a short note the shoe horn essay how to create. The vconfig command was not found. The simplest way to check whether /proc has been mounted is to list the content of that directory. An Ethernet header extension that enlarges the header from 14 to 18 bytes. To configure an Ethernet interface as an ieee 802.1Q vlan trunk on a Debian-based distribution. Eth0 does not exist, unable to create vlan1 run-parts: /etc/network/if-pre-up. First install the vlan package if it is not already present: apt-get install vlan, this provides the command vconfig, which you will not need to invoke directly, but which is needed by ifup and ifdown when using vlans. Vlan with VID 700 to IF -:eth0:- Set IP address ( netmask in this example sudo ifconfig eth0.700 /24 Created interface is named as eth0.700 : sudo ifconfig -a eth0 Link encap:Ethernet HWaddr 84:8f:69:b0:fa:0a UP broadcast multicast MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0. Several vlans can co-exist on a single physical switch, which are configured via. Lines beginning with are ignored. # The loopback network interface auto lo iface lo inet loopback # The primary network interface #allow-hotplug eth0 #iface eth0 inet dhcp auto eth0 iface eth0 inet static address netmask gateway auto vlan119 iface vlan119 inet static vlan -raw-device eth0 address netmask auto vlan101 iface. 64 bytes from : icmp_req1 ttl64 time1.28 ms - ping statistics - 1 packets transmitted, 1 received, 0 packet loss, time 0ms rtt min/avg/max/mdev.282/1.282/1.282/0.000 ms To remove vlan 700 from the eth0 interface execute command: sudo vconfig rem eth0.700 Removed vlan -:eth0.700:- Permanent solution. # # This file contains the names of kernel modules that should be loaded # at boot time, writing paper for exam one per line. Provided you are running a normal stock kernel you can correct this by loading the appropriate modules package, for example: apt-get install linux-image-2.6.26-2-486 If it is a normal installation then a possible explanation is that you are running a different kernel from the one that. Specific to, debian-based distributions, tested on, debian (Etch, Lenny, Squeeze). Maybe you are missing the vlan package, that have the binaries required to configure the interfaces. # The loopback network interface auto lo iface lo inet loopback # The primary network interface allow-hotplug eth0 iface eth0 inet dhcp To create vlan 700 on the eth0 interface at the boot time just add similar configuration: # add vlan 700 on eth0.
