Cisco switch WS-C2960-24TT-L

• 24 Ethernet 10/100 ports and two 10/100/1000TX uplinks
• 1 RU fixed-configuration
• LAN Base Image installedCisco Catalyst WS-C2960-24TT-L-24TT-L: 8 lb (3.6 kg)
• Cisco Catalyst WS-C2960-24TT-L-24TT-L: 1.73 x 17.5 x 9.3 in. (4.4 x 44.5 x 23.6 cm)

To implement QoS, the Cisco Catalyst WS-C2960-24TT-L LAN Base Series Switch first identifies traffic flows or packet groups, then classifies or reclassifies these groups using the differentiated services code point (DSCP) field or the 802.1p class of service (CoS) field. Classification and reclassification can be based on criteria as specific as the source or destination IP address, source or destination MAC address, or the Layer 4 TCP or UDP port. At the ingress, the Cisco Catalyst WS-C2960-24TT-L LAN Base Series also polices to determine whether a packet is in or out of profile, marks to change the classification label, passes through or drops out of profile packets, and queues packets based on classification. Control-plane and data-plane ACLs are supported on all ports to help ensure proper treatment on a per-packet basis.
The Cisco Catalyst WS-C2960-24TT-L LAN Base Series supports four egress queues per port, giving network administrators more control in assigning priorities for the various applications on the LAN. At egress, the switch performs congestion control and scheduling, the algorithm or process that determines the order in which queues are processed. The Cisco Catalyst WS-C2960-24TT-L LAN Base Series Switch supports Shaped Round Robin (SRR) and strict priority queuing.

Cisco Catalyst WS-C2960-24TT-L Series Switches with LAN Base software are a family of fixed-configuration, standalone intelligent Ethernet devices that provide desktop Fast Ethernet and Gigabit Ethernet connectivity, enabling enhanced LAN services for entry-level enterprise, midmarket, and branch office networks.

The Cisco Catalyst WS-C2960-24TT-L LAN Base Series offers:

• Intelligent features at the network edge, such as sophisticated access control lists (ACLs) and enhanced security
• Dual-purpose uplinks for Gigabit Ethernet uplink flexibility, allowing use of either a copper or a fiber uplink-each dual-purpose uplink port has one 10/100/1000 Ethernet port and one Small Form-Factor Pluggable (SFP)-based Gigabit Ethernet port, with one port active at a time
• Network control and bandwidth optimization using advanced QoS, granular rate limiting, ACLs, and multicast services

The Cisco Catalyst WS-C2960-24TT-L LAN Base software image is a rich suite of intelligent services, including advanced QoS, rate limiting, ACLs, and IPv6 management. The SFP-based Gigabit Ethernet ports accommodate a range of SFP transceivers, including the Cisco 1000BASE-SX, 1000BASE-LX, 1000BASE-BX, 1000BASE-ZX, 100BASE-FX, 100BASE-LX, 100BASE-BX, and coarse wavelength-division multiplexing (CWDM) SFP transceivers.

Cisco IBNS in the Cisco Catalyst WS-C2960-24TT-L LAN Base Series prevents unauthorized access and helps ensure that users get only their designated privileges. It provides the ability to dynamically administer granular levels of network access. Using the 802.1x standard and the Cisco Secure Access Control Server (ACS), users can be assigned a VLAN upon authentication, regardless of where they connect to the network. The Cisco Catalyst WS-C2960-24TT-L LAN Base Series is equipped with a large set of features that allow for network scalability and higher availability through multicast filtering as well as a complete suite of Spanning Tree Protocol enhancements aimed to maximize availability in a Layer 2 network. The Cisco Catalyst WS-C2960-24TT-L LAN Base Series offers superior multilayer QoS features to help ensure that network traffic is classified and prioritized and that congestion is avoided in the best possible manner.
