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 ...
Most wireless repeaters (or range extenders) are purpose-built, but certain wireless routers can be flashed with custom firmware such as DD-WRT to give them a 'range extender' option. A better option for extending wireless coverage is to configure a secondary box as a wireless access point , with a wired connection between a LAN port on this ...
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.
Promiscuous port (P-Port): The switch port connects to a router, firewall or other common gateway device. This port can communicate with anything else connected to the primary or any secondary VLAN. In other words, it is a type of a port that is allowed to send and receive frames from any other port on the VLAN. Host 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.
A VLAN access control list (VACL) provides access control for all packets that are bridged within a VLAN or that are routed into or out of a VLAN. Unlike regular Cisco IOS access control lists that are configured on router interfaces and applied on routed packets only, VACLs apply to all packets.
Router R1 is a one-armed router carrying out inter-VLAN routing. A router on a stick, also known as a one-armed router, [1] [2] is a router that has a single physical or logical connection to a network. It is a method of inter-VLAN routing where one router is connected to a switch via a single cable. The router has physical connections to the ...
802.1aq is the IEEE-sanctioned link state Ethernet control plane for all IEEE VLANs covered in IEEE 802.1Q. [28] The Shortest Path Bridging virtual local area network identifier (VLAN ID) or Shortest Path Bridging VID (SPBV) provides a capability that is backward compatible with spanning tree technologies. The SPBM provides additional values ...
