Switch management

Web UI via Cisco Configuration Professional
Cisco Configuration Professional provides a user interface for day-zero provisioning, which enables easy onboarding of the switch. It also has an intuitive dashboard for configuring, monitoring, and troubleshooting the switch.

Bluetooth for over-the-air access
The C1000-48P-4X-L supports an external Bluetooth dongle (sold separately) that plugs into the USB port on the switch and allows a Bluetooth-based RF connection with external laptops and tablets. Laptops and tablets can access the switch CLI using a Telnet or Secure Shell (SSH) client over Bluetooth. The GUI can be accessed over Bluetooth with a browser.

Intelligent PoE+

The Cisco C1000-48P-4X-L Catalyst Switch support both IEEE 802.3af PoE and IEEE 802.3at PoE+ (up to 30W per port) to deliver a lower total cost of ownership for deployments that incorporate Cisco IP phones, Cisco Aironet and Catalyst wireless access points (sold separately), or other standards-compliant PoE and PoE+ end devices. PoE removes the need to supply wall power to PoE-enabled devices and eliminates the cost of adding electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments.

The PoE power allocation in the Cisco C1000-48P-4X-L is dynamic, and power mapping scales up to a maximum of 370W of PoE+ power. Intelligent power management allows flexible power allocation across all ports. With Perpetual PoE, the PoE+ power is maintained during a switch reload. This is important for critical endpoints such as medical devices and for IoT endpoints such as PoE-powered lights, so that there is no disruption during a switch reboot.

Redundancy and resiliency

The C1000-48P-4X-L offers a number of redundancy and resiliency features to prevent outages and help ensure that the network remains available:

  • IEEE 802.1s/w Rapid Spanning Tree Protocol (RSTP) and Multiple Spanning Tree Protocol (MSTP) provide rapid spanning-tree convergence independent of spanning-tree timers and also offer the benefits of Layer 2 load balancing and distributed processing.
  • Per-VLAN Rapid Spanning Tree (PVRST+) allows rapid spanning-tree reconvergence on a per-VLAN spanning-tree basis, without requiring the implementation of spanning-tree instances.
  • Switch-port auto-recovery (error disable) automatically attempts to reactivate a link that is disabled because of a network error.
  • Link state tracking binds the link state of multiple interfaces. The server Network Interface Cards (NICs) form a group to provide redundancy in the network. When the link is lost on the primary interface, network connectivity is transparently changed to the secondary interface.

Enhanced QoS

The Cisco C1000-48P-4X-L Catalyst switch offers intelligent traffic management that keeps everything flowing smoothly. Flexible mechanisms for marking, classifying, and scheduling deliver superior performance for data, voice, and video traffic, all at wire speed. Primary QoS features include:

  • Up to eight (8) egress queues and two (2) thresholds per port, supporting egress bandwidth control, shaping, and priority queuing so that high-priority packets are serviced ahead of other traffic.
  • Ingress policing to allow the analysis of IP service levels for IP applications and services using active traffic monitoring — generating traffic in a continuous, reliable, and predictable manner — for measuring network performance. The number of ingress policers available per port is 64.
  • QoS through Differentiated Services Code Point (DSCP) mapping and filtering.
  • QoS through traffic classification.
  • Trust boundary to configure device-based trust.
  • AutoQoS to simplify the deployment of QoS features.
  • Shaped Round Robin (SRR) scheduling and Weighted Tail Drop (WTD) congestion avoidance.
  • 802.1p Class of Service (CoS) classification, with marking and reclassification.

Energy management

The C1000-48P-4X-L offers a range of industry-leading features for energy efficiency and management:

  • IEEE 802.3az Energy Efficient Ethernet (EEE) enables ports to dynamically sense idle periods between traffic bursts and quickly switch the interfaces into a low-power idle mode, reducing power consumption.
  • Loop detection is a method to detect network loops in the absence of STP.
  • Cisco AutoConfig determines the level of network access provided to an endpoint based on the type of device. This feature also permits hard binding between the end device and the interface.
  • Cisco Auto SmartPorts enables automatic configuration of switch ports as devices connect to the switch with settings optimised for the device type, resulting in zero-touch port-policy provisioning.
  • Cisco Smart Troubleshooting is an extensive array of diagnostic commands and system health checks in the switch, including Smart Call Home. The Cisco Generic Online Diagnostics (GOLD) and online diagnostics on switches in live networks help predict and detect failures more quickly.

Fast and safe delivery

Richard McClintock, a Latin scholar from Hampden-Sydney College, is credited with discovering the source behind the ubiquitous filler text. In seeing a sample of lorem ipsum, his interest was piqued by consectetur—a genuine, albeit rare, Latin word. Consulting a Latin dictionary led McClintock to a passage from De Finibus Bonorum et Malorum On the Extremes of Good and Evil, a first-century B.C. text from the Roman.

Carried only by professionals

So when is it okay to use lorem ipsum? First, lorem ipsum works well for staging. It’s like the props in a furniture store—filler text makes it look like someone is home. The same Wordpress template might eventually be home to a fitness blog, a photography website, or the online journal of a cupcake fanatic. Lorem ipsum helps them imagine what the lived-in website might look like.
