Enhancements to the standard Spanning Tree Protocol, such as Per-VLAN Spanning Tree Plus (PVST+), UplinkFast, and PortFast, help to maximize network uptime.
-
Multilayer QoS features help ensure that network traffic is classified and prioritized, and that congestion is avoided in the best possible manner.
-
Express Setup simplifies initial configuration of a switch through a Web browser.
-
ACLs can be used to restrict access to sensitive portions of the network by denying packets based on source and destination MAC addresses, IP addresses, or TCP/User Datagram Protocol (UDP) ports. ACL lookups are done in hardware, so forwarding performance is not compromised when implementing ACL-based security.
-
Forty-Eight Ethernet 10/100 Base-T ports for desktop connectivity
-
Two 10/100/1000 Ethernet uplink ports
The LAN Lite feature set provides entry-level security, quality of service (QoS), and availability capabilities while lowering the total cost of network ownership.
A similar switch, the WS-C-2960-48TT-L (G-42931,) provides more advanced features but at a higher cost of ownership. See the Cisco Web site for a comparison in PDF form.
The Cisco Identity-Based Networking Services (IBNS) solution provides authentication, access control, and security policy administration to secure network connectivity and resources.
There are two options for switch management: the Windows-based Cisco Network Assistant, available at no cost from the Cisco Web site, http://www.cisco.com/en/US/products/ps5931/index.html and SNMP network-management platforms such as the CiscoWorks LAN Management Solution.
Product service and support: Cisco will provide five years of hardware and software service and support ("SMARTnet") for any product or product bundle obtained through this donation programme.
