Switch Configurations

Table 1. Cisco Catalyst 2960-S Series Switches Configurations

Cisco FlexStack

Cisco FlexStack provides stacking of up to four 2960-S switches through an optional module (Figure 2). The FlexStack stack module is hot-swappable and can be added to any Cisco Catalyst 2960-S switch with LAN

Base software. Switches connected to a stack will automatically upgrade to the stack’s Cisco IOS Software version

and transparently join the stack without additional intervention. Cisco FlexStack and Cisco IOS Software provide true stacking, with all switches in a stack acting as a single switch

unit. FlexStack provides a unified data plane, unified configuration, and single IP address for switch management. The advantages of true stacking include lower total cost of ownership and higher availability through simplified management and cross-stack features including EtherChannel, SPAN, and FlexLink. Note that cross-stack features must be disabled before removing the stack module from an active stack member switch.

FlexStack also allows mixed stacking: 2960-S and 2960-SF switches can be combined to provide a combination of Gigabit and Fast Ethernet ports in a single switch stack.

Figure 2. Cisco FlexStack Switch Stack

Power over Ethernet Plus - PoE+

Cisco Catalyst 2960-S 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

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. Table 2 shows the total PoE/PoE+ power available in each 2960-S model.

Network Security

The Cisco Catalyst 2960-S Series Switches provide a range of security features to limit access to the network and mitigate threats, including:

●

Features to control access to the network, including Flexible Authentication, 802.1x Monitor Mode, and RADIUS Change of Authorization

●

Cisco SXP to simplify security and policy enforcement throughout the network

●

Threat defense features including Port Security, Dynamic ARP Inspection, and IP Source Guard

●

IPv6 First-Hop Security to protect against rogue router advertisements, spoofing, and other risks introduced by IPv6

Enhanced Quality of Service

The Cisco 2960-S Series Switches offers intelligent traffic management that keeps everything flowing smoothly. Flexible mechanisms for marking, classification, and scheduling deliver superior performance for data, voice, and video traffic, all at wire speed. Primary QoS features include:

●

Four egress queues per port and strict priority queuing so that the highest priority packets are serviced ahead of all other traffic

●

Shaped Round Robin (SRR) scheduling and Weighted Tail Drop (WTD) congestion avoidance

●

Flow-based rate limiting and up to 64 aggregate or individual policers per port

●

802.1p class of service (CoS) and differentiated services code point (DSCP) field classification, with marking and reclassification on a per-packet basis by source and destination IP address, MAC address, or Layer 4 TCP/UDP port number

●

Cross-stack QoS to allow QoS to be configured across a stack of 2960-S switches

Cisco Catalyst SmartOperations

Cisco Catalyst SmartOperations is a comprehensive set of capabilities that simplify LAN planning, deployment, monitoring, and troubleshooting. Deploying SmartOperations tools reduces the time and effort required to operate the network and lowers total cost of ownership (TCO).

●

Cisco Smart Install enables zero-touch deployment by providing automated Cisco IOS Software image installation and configuration when new switches are connected to the network.

●

Cisco Auto Smartports enables automatic configuration of switch ports as devices connect to the switch, with settings optimized for the device type.

●

Cisco Smart Troubleshooting is an extensive array of diagnostic commands and system health checks within the switch, including Smart Call Home.
