Intelligent PoE+
Cisco Catalyst 2960-L Switches 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® wireless access points, 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 for IP phone and WLAN deployments.
The Cisco Catalyst 2960-L Switches PoE power allocation 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.
Network Security
Cisco Catalyst 2960-L Switches provide a range of security features to limit access to the network and mitigate threats, including:
● Comprehensive 802.1X Features to control access to the network, including flexible authentication, 802.1X monitor mode, and RADIUS change of authorization.
● 802.1x support with Network Edge Access Topology (NEAT) extends identity authentication to areas outside the wiring closet (such as conference rooms).
● IEEE 802.1x User Distribution enables you to load-balance users with the same group name across multiple different VLANs.
● Disable per-VLAN MAC learning manages the available MAC address table space by controlling which interface or VLANs learn MAC addresses.
● Multidomain authentication to allow an IP phone and a PC to authenticate on the same switch port while being placed on appropriate voice and data VLANs.
● AAA command authorization in plug-and-play (PnP) to enable seamless PnP provisioning.
● Access control lists (ACLS) for IPv6 and IPv4 security and Quality-of-Service (QoS) ACL elements (ACEs).
● Port-based ACLs for Layer 2 interfaces to allow security policies to be applied on individual switch ports.
● SSH, Kerberos, and SNMPv3 to provide network security by encrypting administrator traffic during Telnet and SNMP sessions. SSH, Kerberos, and the cryptographic version of SNMPv3 require a special cryptographic software image because of U.S. export restrictions.
● SPAN, with bidirectional data support, to allow the Cisco Intrusion Detection System (IDS) to take action when an intruder is detected.
● TACACS+ and RADIUS authentication to facilitate centralized control of the switch and restrict unauthorized users from altering the configuration.
● MAC address notification to notify administrators about users added to or removed from the network.
● MAC authentication bypass and Web auth with downloadable ACLs allows per-user ACLs to be downloaded from the Cisco Access Control Server (ACS) as policy enforcement after authentication using MAB or Web authentication in addition to IEEE 802.1X.
● Web Authentication redirection enables networks to redirect guest users to the URL that they had originally requested.
● Multilevel security on console access to prevent unauthorized users from altering the switch configuration.
● BPDU guard to shut down spanning-tree PortFast-enabled interfaces when BPDUs are received to avoid accidental topology loops.
● IP Source Guard restricts IP traffic on nonrouted, Layer 2 interfaces by filtering traffic based on the DHCP snooping binding database or manually configuring IP source bindings.
● SSHv2 allows the use of digital certificates for authentication between user and server.
● Spanning-Tree Root Guard (STRG) to prevent edge devices that are not in the network administrator’s control from becoming Spanning Tree Protocol (STP) root nodes.
● Internet Group Management Protocol (IGMP) filtering to provide multicast authentication by filtering out nonsubscribers and to limit the number of concurrent multicast streams available per port.
● Dynamic VLAN assignment through implementation of VLAN Membership Policy Server client capability to provide flexibility in assigning ports to VLANs. Dynamic VLAN facilitates the fast assignment of IP addresses.
Basic Layer 3 Features
RIP is a commonly used routing protocol in small to medium-sized TCP/IP networks. It is supported in both IPv4 and IPv6 network environments.
Static routing is used to segment the network into separate workgroups and communicate across VLANs without degrading application performance.
Redundancy and Resiliency
Cisco Catalyst 2960-L Switches offer 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 NIC adapters 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
Cisco Catalyst 2960-L Switches offer 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 egress queues and two thresholds per port, supporting egress bandwidth control, shaping, and priority queuing so that high-priority packets are serviced ahead of other traffic.
● Ingress policing allows 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.
● Auto-QoS simplifies 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.
