Cisco® Catalyst® 2960-X Series Switches are fixed-configuration, stackable Gigabit Ethernet switches that provide enterprise-class access for campus and branch applications (Figure 1). Designed for operational simplicity to lower total cost of ownership, they enable scalable, secure and energy-efficient business operations with intelligent services and a range of advanced Cisco IOS® Software features.
Cisco Catalyst 2960-X switches feature:
● 24 or 48 Gigabit Ethernet ports with line-rate forwarding performance
● Gigabit Small Form-Factor Pluggable (SFP) or 10G SFP+ uplinks
● FlexStack Plus for stacking of up to 8 switches with 80 Gbps of stack throughput (optional)
● Power over Ethernet Plus (PoE+) support with up to 740W of PoE budget
● 24-port PoE fanless switch for deployment outside the wiring closet
● Reduced power consumption and advanced energy management features
● USB and Ethernet management interfaces for simplified operations
● Application visibility and capacity planning with integrated NetFlow-Lite
● LAN Base or LAN Lite Cisco IOS® software features
● Enhanced limited lifetime warranty (E-LLW) offering next-business-day hardware replacement
Cisco Catalyst 2960-XR models also offer:
● Power resiliency with optional dual field-replaceable power supplies
● IP Lite Cisco IOS® software with dynamic routing and Layer 3 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.
