Setting up the VLAN interfaces (as root): # modprobe 8021q. You may skip the line above if your kernel was compiled with 802.1q and not as module. In Red Hat Enterprise Linux 7, the 8021q module is loaded by default. If necessary, you can make sure that the module is loaded by issuing the following command as root: ~]# modprobe --first-time 8021q modprobe: ERROR: could not insert '8021q': Module already in kernel. Linux has the ability to use an Ethernet interface as an 802.1Q trunk port, allowing it to concurrently send and receive traffic on multiple VLANs. This is provided by the 8021q kernel module, which can be configured non-persistently using the ip link command: An 802.1Q VLAN tagging interface can be created on top of bridge, bond, and team interfaces, however there are some things to note: In the case of VLANs over bonds, it is important that the bond has slaves and that they are “ up ” before opening the VLAN interface.

Some switches have the ability to assign multiple VLANs to a single network port. With this feature, you can assign multiple VLANs to a single server. 2010-01-21 2005-10-13 1. Check that the module is loaded by running the command: # lsmod | grep 8021q. 2.

###1. linux 虚拟网络接口. 在linux的网络设备驱动框架里面，使用一个net_device来代表一个网络设备接口，因此，一个物理网卡对应着一个net_device结构.

Single-tagged 802.1Q VLANs can be configured using the vconfig command, but this does not support 802.1ad. tc-vlan(8) — Linux manual page. The vlan action allows to perform 802.1Q en- or decapsulation on a packet, reflected by the operation modes POP, Instant Configuration.

Mac OS Supports IEEE 802.1Q VLAN tagging. • Supports 16k Jumbo frames. Systemkrav. • Linux Kernel 3.12 or above. • Windows 7/7-64/8.1/8.1-64/10/10-64. • PC with Stödjer IEEE 802.1Q Virtual LAN (VLAN).

802.1q provides for an additional 4-bytes of information added to the L2 frame, 12 bits of which indicate the VLAN is. Thus one may have 4K VLANs. When you want to configure a VLAN in Linux, assuming your kernel supports it (2.6+ do) you need to make sure 802.1q support is available. ISL came first, and was a cisco proprietary protocol that they built into their switches while the dot1Q standard was still in development.
