VLAN Mapping Cisco Switch Configuration: Today i will show you how to configure VLAN mapping cisco switch. [boxads] Here we Map Vlan 10 to VLAN 20 in Gigabit Ethernet port 0/1: Switch# configure terminal Switch(config)# interface gigabitethernet 0/1 Switch(config-if)# switchport mode trunk Switch(config-if)# switchport vlan mapping 10 20 Switch(config-if)# switchport vlan mapping 11 21 Switch(config-if)# switchport vlan mapping 12 22 Switch(config-if)# switchport vlan mapping drop default Switch(config-if)# end Switch# So all incoming Vlan 10 of gi0/1 interface is Converted/Translated to Vlan 20. same way Vlan 11, 12 mapping with 21, 22. How to verify the configuration: Switch# show vlan mapping or …

Huawei Switch Configuration Tutorial: Today i will discuss how to configure a new huawei switch, so lets go our Huawei Switch Configuration Tutorial part…………[boxads] Procedure: Step 1: Connect the COM port on the PC and the console port on the switch by a cable. Step 2: Power on all devices to perform a self-check. Step 3: Run the terminal emulation program on the PC, setting the communication parameters as follows: -Baud rate: 9600 bps -Data bit: 8 -Stop bit: 1 -Parity: none -Flow control: none # Set system name / Host name: <Quidway> System-View [Quidway] sysname Switch-1 [Switch-1]quit

Layer 2 Switching process Today I will discuss about Layer 2 Switching process. A Process of using the MAC address on LAN is called Layer 2 Switching. Layer 2 Switching is the process of using hardware address of devices on a LAN to segment a network. Switching breaks up large collision domains into smaller ones and that a collision domain is a network segment with two or more devices sharing the same bandwidth. [boxads] Ethernet is a LAN technology based on the IEEE 802.3 standard. It provides a shared medium to transfer the data. There are three Switching Modes: Cut …

OSPF LSA Types: [boxads] There are different types of link-state advertisements (LSAs) that would be used for Open Shortest Path First (OSPF). This article contains List of OSPF LSA types with a short description. LSAs build up the OSPF link state database (LSDB), and they are exchanged between OSPF enabled nodes. Bellow short description of OSPF LSA types. LSA Type 1 (Router LSA): LAS type 1 are generated by every router of an OSPF area. They are flooded to all other routers only inside an area of origin & directly connected router. In the link-state ID you will find the originating router’s ID. …

OSPF Message Types: [boxads] There are several types of message are passes through OSPF network for communication each other. that OSPF Message Types are given bellow: 1. Hello : These messages are used to establish neighbor ship and serve as keepalives among other things. They are also used to elect the Designated Router (DR) and Backup Designated Router (BDR) on multiaccess networks (like Ethernet or Frame Relay). Sent on 224.0.0.5 and 224.0.0.6 Contains the following in the packet; RID of interface Authentication Hello Dead Timers Area ID Nieghbor List (If not a nieghbor, sends more info) Designated Router IP Backup DR …

OSPF Area Types: [bodyads] OSPF is a widely used protocol in service provider environments. Now a days the majority of the network setups use this protocol. OSPF is well suited for multi-vendor environments. OSPF allows 5 different area types, which provides flexibility, fast convergence and scalability. OSPF area types are: Backbone/ Non-backbone Stub Area Totally Stubby Area Not-So-Stubby Area (NSSA) Totally Not-So-Stubby Area (NSSA) Backbone area: The backbone area is the core of an OSPF network (also this area known as area 0 or area 0.0.0.0). All other areas are connected to backbone area, and inter-area routing happens via routers …
