May 6, 2009 · Backplane is the discreet circuitry that allows different computer components to communicate within the system's frame. A good example within a network device would be a chassis system. When you insert a card, it connects to the backplane.

May 8, 2010 · Backplane bandwidth for connecting the 48 ports (and network module, if fitted) is sufficient to enable non-blocking. However, 48 ports x 1Gbps (plus potentially 2 x 10Gbps in network module) definitely doesn't squeeze into 32Gbps stack ring, so …

Jun 25, 2014 · When the switch is a modular type (i.e., with linecards inserted into a chassis), the backplane (or midplane depending on the architecture) is the physical set of connections that allow signals to travel among the cards.

Aug 5, 2008 · But because the backplane only supports 16 Gbps, duplex (32), the bottleneck on the 2960G-24 would be the backplane. An example of an Ethernet "wire speed" or "line rate" switch is the 4948, 48 gig Ethernet ports, rated at 72 Mpps and 96 Gbps fabric.

Nov 13, 2008 · Backplane bandwidth is the available bandwidth between the device's ports. To better understand this, consider two external 8 port switches that you interconnect with a single uplink. If the all ports were 100 Mbps, the uplink would become a bottleneck for traffic between the two switches since it too is only 100 Mbps.

Jul 20, 2006 · Backplane bandwidth is generally referred to as the aggregate bandwidth available among all the ports. It is the switch pipe through which input flows towards the output port. It is also referred to as the switch fabric. Hope this helps. Regards, AbhisheK. Please rate all posts!!!

Dec 21, 2012 · The IOM "backplane" links come up automatically when there's a service profile configured. These aren't something you have control enabling/disabling. Second, you can't fit 7x B200's (1/2 width server) and a B440 (full width server) in a single Chassis.

Jan 30, 2014 · I have read on several pages that the 3750 x (WS-C3750X-48) has a 64 Gbps backplane and about 101 Mpps throughput. I'm looking to clairfy that the 64 Gbps is on a single standalone switch, not stacked to equal 64 Gbps. I looks like the switch supports line rate non-blocking. CORE.1#show plat pm if-numbers

Jan 2, 2017 · The Cisco Catalyst 6500 chassis also includes a second backplane that allows line cards to connect over a high-speed switching path into a crossbar switching fabric. The crossbar switching fabric provides a set of discrete and unique paths for each line card to both transmit data into and receive data from the crossbar switching fabric.

Mar 31, 2014 · Backplane and switching capacities are slightly different. Backplane capacity is similar to bus speed in a computer. It defines the bandwidth of the module-to-module interconnect in large multi-module switches. Backplane speed is just one component of total speed, it means total backplane throughput of a switch would be the sum of the port speeds.
