Les 4 types de segments
Quels sont les 4 types de segments ? Il existe 4 éléments à prendre en compte lorsqu’il est question de segmenter une audience en marketing: Segmentation géographique: Divise le marché en fonction de l’emplacement géographique (pays, région, ville). Par exemple, une entreprise de vêtements peut cibler différentes collections en fonction...
En savoir plusPrincipal inconvénient de l'utilisation d'un VLAN
Le principal inconvénient du Vlan par port est qu'il nécessite une configuration lourde et contraignante sur chaque switch. A chaque déplacement de poste, il faut modifier les switchs correspondant pour maintenir une qualité de service. Ce système peut être atténuer par la mise en place d'une solution de carte client...
En savoir plusDifférence entre VRV et VRF
Traditionally, an air conditioning system only includes single, unconnected units which cannot modify temperatures from room to room, or maintain an entire house at one uniform temperature. Variable Refrigerant Volume (VRV)/Variable Refrigerant Flow (VRF) technology make it easier to do this. These newer systems use multiple indoor units, connected to...
En savoir plusDifférence entre LAN et WAN
Fundamentally, both local area networks (LANs) and wide area networks (WANs) connect several devices. However, a WAN can be made up of multiple interconnected LANs. A WAN is a network that connects multiple LANs over a long distance to allow devices to communicate over a wide area.
LANs use data...
En savoir plusLes 3 segments
Les trois segments d'un segment de piston sont principalement divisés en deux types : le segment d'huile au niveau du trou de l'axe de piston et les deux autres segments sont des segments de compression. Le segment de compression, également connu sous le nom de segment supérieur, est principalement utilisé...
En savoir plus802.1Q и ISL
ISL and 802.1Q are trunking protocols.
Trunk ports use them to encapsulate and de-encapsulate Ethernet frames.
A trunk port can use only one protocol from these at a time.
Differences between ISL and 802.1Q The following table compares ISL with 802.1Q and lists the differences between them.
ISL stands... En savoir plusMain Benefit of RSTP over STP
RSTP is an enhanced version of STP and was designed to overcome the limitations of STP.
Faster convergence time to reduce network downtime and performance improvement.
Detect changes in network topology in quick manner and reconfigure network.
Supports rapid convergence less than 1 second.
Proposal and agreement handshake on point-to-point...
En savoir plusDifference Between MSTP and RPVST Spanning Tree Protocols
Multiple Spanning Tree Protocol (MSTP) IEEE 802.1s – allows us to create multiple separate spanning-tree instances, and it enables us to map and allocate multiple VLANs to the instances.
Rapid Per VLAN Spanning Tree Plus (RPVST+) Protocol – Cisco-proprietary enhancement to the IEEE 802.1w RSTP. Similar to PVST+, it enables us...
En savoir plusEquivalence of LACP and EtherChannel
EtherChannel links formed when two or more links budled together for the purposes of aggregating available bandwidth and providing a measure of physical redundancy.
Standards-based negotiation protocol, known as IEEE 802.1ax Link Aggregation Control Protocol, is simply a way to dynamically build an EtherChannel.
Essentially, the “active” end of the...
En savoir plusDifference Between EtherChannel and Link Aggregation
Link aggregation (LAG) is simply a means to bundle multiple ethernet connections between a pair of switches to share the load. EtherChannel is Cisco's pre-standards model for doing so, which was originally inherited from the Kalpana acquisition. IEEE 802.3ad describes the standard way to aggregate links, including the Link Aggregation...
En savoir plusUses of LACP
LACPLACP is a useful bonded broadband tool for upgrading your link aggregation group (LAG).
There are network devices that have support for Link Aggregation Control Protocol (LACP), and this is helpful in preventing faults in the process of setting up link aggregation.
Dynamic LAGs leverage Link Aggregation Control Protocol (LACP)...
En savoir plusChoosing LACP over PAgP in EtherChannel Creation
LACP is the IEEE Standard (IEEE 802.3ad) and is the most common dynamic ether-channel protocol, whereas PAgP is a Cisco proprietary protocol and works only between supported vendors and Cisco devices. All ports in an EtherChannel must use the same protocol; you cannot run two protocols on two ends. In...
En savoir plusDifference Between SSID, BSSID, and ESSID
ESS is the union of a set of BSS's. ESSID and BSSID are just their IDs respectively.
ESSID is the name of the access point, which can be changed. BSSID is a numeric ID of the access point (something like the MAC address of the router). For instance, on my...
En savoir plusThe Equivalence of BSSID and SSID
ESSID and BSSID are just their IDs respectively.
My understanding is that ESSID is the name of the access point, which can be changed.
On the other hand, BSSID is a numeric ID of the access point (something like the MAC address of the router).
For instance, on my college...
En savoir plusESS ID
The Extended Service Set Identification (ESSID) is an identifier for your wireless network.
Specify the ESSID for the current wireless configuration.
For printers with Protected Mode enabled, you cannot modify this setting from the front panel.
