vPC vs VSS

Si l’objectif “historique” est le même : s’affranchir de la limitation de STP (blocage de ports pour prévenir les boucles), de l’usage des FHRP (HSRP, VRRP) pour équilibr...

  • Transmit Power Control in IEEE 802.11 Cisco WLAN networks
    TPC stands for Transmit Power Control. It’s a one of Cisco RRM, Radio Resources Management, techniques that are aimed at tackling interference, cross and co-channel, in Wlan networks. RRM: TPC, CHD and DCA It works tightly with CHD, Covergate Hole Detection, to optimize transmit power. TPC tends to minimize the transmit power and CHD to eliminate
  • 10 security measures against 10 attacks in a LAN network – Part I
    An Ethernet switch is the central element of a LAN network and operates at data link OSI layer. Every switch port defines a collision domain and can extend a broadcast or broadcast frame domain that is stopped by a router routed interface that operates at network OSI layer. By default switches support one broadcast domain
  • Understand how Aruba ARMizes your WLAN for sure!
    Presenting ARM In this post, that is a part of a serie of post that discuss how Wlan to radio ressources management, we talk of Aruba way of doing it. The figure shows a simple wlan network of 6 AP or access points. This is heatmap showing that radio signal is very strong (in red)
  • Understand RIP Routing Timers All in One Shot!
    This post is part of a series of posts about dynamic routing protocols and especially RIP. We’ll try to get a deep understanding of its operation and function as an introductory to dynamic routing logic in general. You’ll see that what we think easy may hide an incrementing complexity… a little introduction Berfore we start
  • DUAL route FSM Processing of EIGRP Queries
    This blog is a part of series of posts about EIGRP routing protocol. Let’s recall that EIGRP is one of the so called IGP routing protocols. IGP stands for interior routing protocols as opposed to EGP or exterior routing protocols. In addition EIGRP is a hybrid as it borrows some similiarities to distance-vector and link-state
