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. Only one VLAN interface can be associated with a VLAN, but you need to configure a VLAN interface for a VLAN only when ...
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.
VLAN cross connect (CC or VLAN-XC) is a mechanism used to create Switched VLANs, VLAN CC uses IEEE 802.1ad frames where the S Tag is used as a Label as in MPLS. IEEE approves the use of such a mechanism in part 6.11 of IEEE 802.1ad-2005 .
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.
This is a list of all Internet Relay Chat commands from RFC 1459, RFC 2812, and extensions added to major IRC daemons. Most IRC clients require commands to be preceded by a slash (" / "). Some commands are actually sent to IRC bots ; these are treated by the IRC protocol as ordinary messages, not as / -commands.
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 ...
Cisco Inter-Switch Link (ISL) is a Cisco proprietary link layer protocol that maintains VLAN information in Ethernet frames as traffic flows between switches and routers, or switches and switches. [1] ISL is Cisco's VLAN encapsulation protocol and is supported only on some Cisco equipment over the Fast and Gigabit Ethernet links.
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.
