What is fabric card Cisco?
The switch fabric is the core of the Cisco CRS 4-slot line card chassis. The switch fabric receives user data from an MSC and performs the switching necessary to route the data to the appropriate egress MSC.
What is a fabric card chassis?
Switch Fabric Card (Single-Chassis System) In a single chassis, the switch fabric card implements all three stages of the three-stage Benes switch fabric. Each card also implements one plane of the eight-plane switch fabric.
What are Cisco line cards?
What is a Line Card? A Cisco switch line card is a printed circuit board that provides a transmitting/receiving port for a local area network (LAN) or a wide area network (WAN). Cisco line cards plug into telephone switches and routers that have a modular chassis.
What is Nexus fabric?
Fabric Modules are like backplane of nexus Switches, when all the Line cards, Supervisor are inserted to nexus Chassis, then all line cards and supervisor modules are connected to each other via fabric Module. Fabric Module are like Meeting point of all line cards and supervisor modules.
What is a line card slot?
The MSC, FP, and LSP card, also called line cards, are the Layer 3 forwarding engine in the CRS 8-slot routing system. A line card can be paired with different types of PLIMs to provide a variety of packet interfaces, such as OC-192 POS and OC-48 POS.
What are carrier grade routers?
Carrier Routing System (CRS) is a modular and distributed core router developed by Cisco Systems Inc that enables service providers to deliver data, voice, and video services over a scalable IP Next-Generation Network (NGN) infrastructure.
What are line cards used for?
A line card have commonly been used to interface the twisted pair cable of a POTS local loop with the public switched telephone network (PSTN). Line cards used on the PSTN may have many functions, including: conversion of voice transmissions from analog to digital or vice versa. detection of off-the-hook receivers.
What is line card in router?
A printed circuit board that provides a transmitting/receiving port for a local area network (LAN) or a carrier’s telephone or wide area network (WAN). Small and medium-size routers have a fixed number of ports, typically Ethernet, and the line card circuitry is built into each port.
What is chassis in Cisco router?
Chassis aggregation is a Cisco technology to make two switches operate as a single logical switch. The two core switches will act as a single switch to the outside world when it comes to control plane protocols like ARP, spanning-tree, EtherChannel and routing protocols.
Which of the following hardware components is an associated pair of cards that mate through the chassis midplane?
The line card and PLIM are an associated pair of cards that mate through the chassis midplane.
What is the difference between line cards and fabric cards in a router?
“The Cisco NCS 6000 Series Routers include the Cisco NCS 6008 Line Card Chassis (LCC) and the Cisco NCS 6000 Fabric Card Chassis (FCC).” Are those part of the same machine? What’s the difference between fabric and line cards?
What is the role of fabric cards in Cisco routing system?
The fabric cards (FCs) provide the switch fabric for the routing system and perform the cross-connect function of the routing system, connecting every line card (LC) to each other. The switch fabric receives ingress user data from one LC slot and performs the switching necessary to route the data to the appropriate egress LC slot.
What are the features of the Cisco NCS 6008 LCC?
The Cisco NCS 6008 LCC has cable management features for both the front and rear sides of the chassis. These features organize the interface cables entering and exiting the different cards, keeping them out of the way and free of sharp bends that may damage the cables.
When to use compact mode with Cisco fabric?
When a chassis contains only switch fabric-enabled modules, the fabric-enabled line cards can run in compact mode. This delivers the best possible switching rate in CatOS, depending on the line cards. This mode is only available in the Cisco IOS Software with the fabric-enabled line cards that have a DFC.
