The Berkeley Software Distribution UNIX operating systems (e.g., NetBSD, OpenBSD, and FreeBSD) continue active development of ifconfig and extension of its functionality to cover the configuration of wireless networking interfaces, VLAN trunking, controlling hardware features such as TSO or hardware checksumming or setting up bridge and tunnel ...
This is known as inter-VLAN routing. On layer-3 switches it is accomplished by the creation of layer-3 interfaces (SVIs). Inter VLAN routing, in other words routing between VLANs, can be achieved using SVIs. [1] SVI or VLAN interface, is a virtual routed interface that connects a VLAN on the device to the Layer 3 router engine on the same device.
With a VLAN Management Policy Server (VMPS), an administrator can assign switch ports to VLANs dynamically based on information such as the source MAC address of the device connected to the port or the username used to log onto that device. As a device enters the network, the switch queries a database for the VLAN membership of the port that ...
SPBV supports a VLAN using a VLAN Identifier (VID) per node to identify the shortest path tree (SPT) associated with that node. SPBM supports a VLAN by using one or more Backbone MAC addresses to identify each node and its associated SPT, and it can support multiple forwarding topologies for load sharing across equal cost trees using a single B ...
A Private VLAN divides a VLAN (Primary) into sub-VLANs (Secondary) while keeping existing IP subnet and layer 3 configuration. A regular VLAN is a single broadcast domain, while private VLAN partitions one broadcast domain into multiple smaller broadcast subdomains. Primary VLAN: Simply the original VLAN. This type of VLAN is used to forward ...
Simply do not put any hosts on VLAN 1 (the default VLAN). i.e., assign an access VLAN other than VLAN 1 to every access port Switch (config-if)# switchport access vlan 2; Change the native VLAN on all trunk ports to an unused VLAN ID. Switch (config-if)# switchport trunk native vlan 999; Explicit tagging of the native VLAN on all trunk ports.
IEEE 802.1Q, often referred to as Dot1q, is the networking standard that supports virtual local area networking (VLANs) on an IEEE 802.3 Ethernet network. The standard defines a system of VLAN tagging for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames.
More commonly, the desired command names are linked (using hard or symbolic links) to the BusyBox executable; BusyBox reads argv[0] to find the name by which it is called, and runs the appropriate command, for example just /bin/ls. after /bin/ls is linked to /bin/busybox. This works because the first argument passed to a program is the name ...
