Ease of Use: Deployment
Ease-of-use features include but are not limited to:
●
Smartports enable fast and easy configuration of Cisco recommended best-practice
security and QoS features, encapsulating years of Cisco networking expertise.
●
Dynamic Host Configuration Protocol (DHCP) autoconfiguration of multiple switches
through a boot server eases switch deployment.
The Cisco Catalyst 2960 LAN Lite Switches are equipped with features that allow for network
scalability and higher availability through multicast filtering as well as a complete suite of Spanning
Tree Protocol enhancements for maximizing availability in a Layer 2 network.
Enhancements to the standard Spanning Tree Protocol, such as Per-VLAN Spanning Tree Plus
(PVST+), UplinkFast, and PortFast, help to maximize network uptime. PVST+ allows for Layer 2
load sharing on redundant links to efficiently use the extra capacity inherent in a redundant design.
UplinkFast, PortFast, and BackboneFast all greatly reduce the standard 30- to 60-second
Spanning Tree Protocol convergence time. The Loopguard and bridge-protocol-data-unit (BPDU)
Guard enhancements provide Spanning Tree Protocol loop avoidance.
Quality of Service
The Cisco Catalyst 2960 LAN Lite Switches offer QoS features to help ensure that network traffic
is classified and prioritized and that congestion is avoided in the best possible manner. To
implement QoS, the Cisco Catalyst 2960 Series Switches first identify traffic flows or packet
groups, and then classify or reclassify these groups using the 802.1p Class of Service (CoS) field.
The Cisco Catalyst 2960 LAN Lite Switches support four egress queues per port, giving your
network administrators more control in assigning priorities for the various applications on the LAN.
At egress, the switches perform congestion control and scheduling, the algorithm or process that
determines the order in which queues are processed. The Cisco Catalyst 2960 LAN Lite Switches
support Shaped Round Robin (SRR) and Strict Priority Queuing. The SRR algorithm helps ensure
differential prioritization.
Management
The new Express Setup feature simplifies the initial configuration of a switch. Now you can set up
the switch through a web browser, eliminating the need for terminal-emulation programs and the
command-line interface (CLI). Express Setup reduces the cost of deployment by helping less-
skilled personnel set up switches quickly and easily.
Cisco Network Assistant is a PC-based network-management application optimized for LANs with
up to 250 users. Offering centralized management of Cisco switches, routers, and wireless LAN
(WLAN) access points, it supports a wide range of Cisco Catalyst intelligent switches from the
Cisco Catalyst 2960 through the Cisco Catalyst 4506 Switch. Through a user-friendly GUI, you can
configure and manage a wide array of switch functions and start the device manager of Cisco
routers and Cisco wireless access points. A few mouse clicks enable the Cisco recommended
security, availability, and QoS features without the need to consult a detailed design guide. The
Security wizard automatically restricts unauthorized access to servers with sensitive data.
Smartports and wizards save time for network administrators, reduce human errors, and help
ensure that the configuration of the switch is optimized for these applications. You can download
Cisco Network Assistant from the Cisco Website for free.
