Speaking about the various features: IP routing - Layer 2 and 3 switch ports - DHCP pool - ACLs - Stacking. Layer 3 switches cost more than traditional switches but less than traditional routers. Configuring and administering these switches and VLANs. This article covers basic and advanced configuration of Cisco Catalyst Layer 3 switches such as the Cisco Catalyst G, E, X.

L3 SWITCH CONFIGURATION PDF


The bridge learns the MAC address of each connected device. Bridges also buffer an incoming packet and adapt the transmission speed to that of the outgoing port.

While there are specialized applications, such as storage area networks, where the input and output interfaces are the same bandwidth, this is not l3 switch configuration the case in general LAN applications.

In LANs, a switch used for end user access typically concentrates lower bandwidth and uplinks into a higher bandwidth. Interconnect between switches may be regulated using spanning tree l3 switch configuration STP that disables links so that the resulting local area network is a tree without loops.

In contrast to routers, spanning tree bridges must have topologies with only one active path between two points. Shortest path bridging is a layer 2 alternative to STP allows all paths to be active with multiple equal cost l3 switch configuration.

Most network switches, however, are limited to supporting a single type of physical network, typically Ethernet, whereas a router may support different kinds of physical networks on different ports.

With this awareness, a layer-3 switch can increase efficiency by delivering the traffic of a multicast group only to ports where the attached device has signalled that it wants to listen to that group.

Some layer-3 switches support the routing protocols that routers use to exchange information about routes between networks. Layer l3 switch configuration edit ] While the exact meaning of the term layer-4 switch is vendor-dependent, it almost always starts with l3 switch configuration capability for network address translation ,[ citation needed ] and may add some type of load distribution based on TCP sessions or advanced QoS capabilities.

Layer 7[ edit ] Layer-7 switches may distribute the load based on uniform resource locators URLsor by using some installation-specific technique to recognize application-level transactions.

A layer-7 switch l3 switch configuration include a web cache and participate in a content delivery network CDN. Rack-mounted switches may be standalone units, stackable switches or large chassis units with swappable line cards.

How to configure a Cisco Layer 3 switch-InterVLAN Routing

Configuration options[ edit ] Unmanaged switches have no configuration interface or options. They are plug and play.

Unmanaged switches can be desktop or rack mounted. Managed switches have one or more methods to modify the operation of the switch. Common management methods include: Examples of configuration changes that one can do from a managed switch include: Two sub-classes of l3 switch configuration switches are smart and enterprise managed switches.

Network switch - Wikipedia

Smart or intelligent switches are managed switches with a limited set of management features. See the l3 switch configuration below: Two Vlans are configured on the L3 switch, Vlan10 and Vlan These two IP addresses will be the default gateway addresses for hosts belonging to Vlan10 and Vlan20 on the Layer2 switches respectively.

Take for example the popular Catalyst Cisco series switches — these Layer 2 switches provide l3 switch configuration healthy amount of features in speed, functionality and security, leaving very little to be desired even in very demanding network environments.

Making InterVLAN routing possible requires a switch or any other device that operates at the 3rd layer of the OSI model, this translates to a router Router-on-a-stick methodlayer 3 switch or server. Readers interested are encouraged to visit the Firewall.

Introducing Cisco Catalyst Layer 3 Switches Cisco produces a number of high-end switches that are capable of delivering Layer 3 routing functionality within an enterprise network of any size.
