Intelligent Power over Ethernet Plus

Cisco Catalyst 2960-Xseries switches support both IEEE 802.3af Power over Ethernet (PoE) and IEEE 802.3at PoE+ (up to 30W per port) to deliver lower total cost of ownership for deployments that incorporate Cisco IP phones, Cisco Aironet^® wireless access points, or other standards-compliant PoE/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 Catalyst 2960-X series PoE power allocation is dynamic and power mapping scale up to a maximum of 740W PoE+ power.

The 2960-XR switch configurations offer the additional benefit of dual redundant power supplies. If both power supplies are used, then the 2960-XR shares the load between the two power supplies for non stop power.

Operational Simplicity Features

●   Cisco AutoSecure provides a single-line CLI to enable base line security features (Port Security, DHCP snooping, DAI). This feature simplifies security configurations with a single touch.

●   Dynamic Host Configuration Protocol (DHCP) autoconfiguration of multiple switches through a boot server eases switch deployment.

●   Stacking master configuration management and Cisco FlexStack Plus technology helps ensure that all switches are automatically upgraded when the master switch receives a new software version. Automatic software version checking and updating help ensure that all stack members have the same software version.

●   Autonegotiation on all ports automatically selects half- or full-duplex transmission mode to optimize bandwidth.

●   Dynamic Trunking Protocol (DTP) facilitates dynamic trunk configuration across all switch ports.

●   Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel^® groups or Gigabit EtherChannel groups to link to another switch, router, or server.

●   Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with devices that conform to IEEE 802.3ad. This feature is similar to Cisco EtherChannel technology and PAgP.

●   Automatic media-dependent interface crossover (MDIX) automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight-through) is installed.

●   Unidirectional Link Detection Protocol (UDLD) and Aggressive UDLD allow unidirectional links caused by incorrect fiber-optic wiring or port faults to be detected and disabled on fiber-optic interfaces.

●   Switching Database Manager (SDM) templates for access, routing, and VLAN deployment allow the administrator to easily maximize memory allocation to the desired features based on deployment-specific requirements.

●   Local Proxy Address Resolution Protocol (ARP) works in conjunction with Private VLAN Edge to minimize broadcasts and maximize available bandwidth.

●   VLAN1 minimization allows VLAN1 to be disabled on any individual VLAN trunk.

●   Smart Multicast, with Cisco FlexStack-Plus technology, allows the Cisco Catalyst 2960-X Series to offer greater efficiency and support for more multicast data streams such as video by putting each data packet onto the backplane only once.

●   Internet Group Management Protocol (IGMP) Snooping for IPv4 and IPv6 MLD v1 and v2 Snooping provide fast client joins and leaves of multicast streams and limit bandwidth-intensive video traffic to only the requestors.

●   Multicast VLAN Registration (MVR) continuously sends multicast streams in a multicast VLAN while isolating the streams from subscriber VLANs for bandwidth and security reasons.

●   Per-port broadcast, multicast, and unicast storm control prevents faulty end stations from degrading overall systems performance.

●   Voice VLAN simplifies telephony installations by keeping voice traffic on a separate VLAN for easier administration and troubleshooting.

●   Cisco VLAN Trunking Protocol (VTP) supports dynamic VLANs and dynamic trunk configuration across all switches.

●   Remote Switch Port Analyzer (RSPAN) allows administrators to remotely monitor ports in a Layer 2 switch network from any other switch in the same network.

●   For enhanced traffic management, monitoring, and analysis, the Embedded Remote Monitoring (RMON) software agent supports four RMON groups (history, statistics, alarms, and events).

●   Layer 2 trace route eases troubleshooting by identifying the physical path that a packet takes from source to destination.

●   Trivial File Transfer Protocol (TFTP) reduces the cost of administering software upgrades by downloading from a centralized location.

●   Network Timing Protocol (NTP) provides an accurate and consistent timestamp to all intranet switches.

Power Management

The 2960-X switches offer a range industry leading features for effective energy efficiency and energy management. 2960-X Series are the greenest switches in the industry.

Switch Hibernation Mode (SHM) is an industry first and available on all 2960-X series switches. This feature puts the switch in ultra low power mode during periods of non-operation such as nights or weekends. Switch Hibernation Mode on the 2960-X switches can be scheduled using EnergyWise compliant management software.

IEEE 802.3az EEE (Energy Efficient Ethernet) enables ports to dynamically sense idle periods between traffic bursts and quickly switch the interfaces into a low power idle mode, reducing power consumption.

Cisco EnergyWise policies can be used to control the power consumed by PoE-powered endpoints, desktop and data-center IT equipment, and a wide range of building infrastructure. EnergyWise technology is included on all Cisco Catalyst 2960-X Series Switches.
