A. Yes. Cisco Catalyst 2960 switches with LAN Base software support IPv6 management and MLD Snooping. The Cisco Catalyst 2960 LAN Lite switches do not support IPv6.
Q. Why do I need intelligence at the edge of my network?
A. Networks have evolved to address four new developments at the network edge:
• Increase in desktop computing power
• Introduction of bandwidth-intensive applications
• Expansion of highly sensitive data on the network
• Presence of multiple device types, such as IP phones and wireless LAN access points
These new demands compete for resources with many existing mission-critical applications. As a result, IT professionals must view the edge of the network as critical to effectively manage the delivery of information and applications. As companies increasingly rely on networks as the strategic business infrastructure, it is important to help ensure their high availability, security, scalability, and control. By adding intelligent functions to the wiring closet, you can deploy networkwide intelligent services that address these requirements in a consistent way from the desktop to the core and through the WAN. Cisco Catalyst Intelligent Ethernet switches can help you realize the full benefits of adding intelligent services to your network. Deploying capabilities that make the network infrastructure highly available to accommodate time-critical needs, scalable to accommodate growth, secure enough to protect confidential information, and capable of differentiating and controlling traffic flows is the basis of further optimizing network operations.
Q. Can you provide more details about how Cisco intelligent switching will help my network?
A. New applications are requiring higher bandwidth and the need to differentiate and control the traffic flow. Applications such as enterprise resource planning (ERP; Oracle or SAP, for example), voice (IP telephony traffic), and computer-aided design and manufacturing (CAD/CAM) require priority over less time-sensitive applications such as FTP or Simple Mail Transfer Protocol (SMTP). It is undesirable to have a large file download destined to one port on a switch increasing latency in voice traffic destined to another port on the same switch. This condition is avoided by making sure that voice traffic is properly classified and prioritized throughout the network. Cisco Intelligent Ethernet switches implement superior QoS to help ensure that network traffic is classified and prioritized and congestion is avoided.
Q. How do Cisco Intelligent Ethernet switches manage the security needs of a network?
A. With the rise in internal threats to a network, Cisco Intelligent Ethernet switches enhance data security through a wide range of features, including SSH Protocol, SNMPv3, ACLs, 802.1x, port security, Private VLAN Edge, Dynamic Host Configuration Protocol (DHCP) Interface Tracker, MAC address notification, and RADIUS/TACACS+. Depending on your security needs, the Cisco Catalyst 2960 Series complements devices such as firewalls, VPNs, and intrusion detection systems (IDSs).
Q. How can I protect unauthorized users from accessing my network?
A. The Cisco Catalyst 2960 Series supports the IEEE 802.1x standard, which works in conjunction with a RADIUS server to authenticate users as they access a network. The 802.1x standard is considered port-level security and is commonly used for wireless LANs. Additionally, portions of the network can be restricted by using ACLs. Access can be denied based on MAC addresses, IP addresses, or TCP/UDP ports. ACL lookups are done in hardware and do not compromise forwarding and routing performance. An additional protection method is to use port security, which helps ensure the appropriate user is on the network by limiting access to the port based on MAC addresses.
Q. How can I monitor or track activities in my network?
A. IDSs are tailored to monitor and track activities in a network. The Cisco Catalyst 2960 Series can complement this through features such as MAC address notification, which sends an alert to a management station so that network administrators know when and where users came on the network and can take appropriate actions. The DHCP Interface Tracker (Option 82) feature tracks where a user is physically connected on a network by providing both switch and port ID to a DHCP server. DHCP Snooping enables the administrator to keep track of both dynamic and static IP/MAC mapping tables.
Q. How can I protect administration passwords and traffic going to the switch during configuration or troubleshooting?
A. To protect administration traffic during the configuration or troubleshooting of a switch (such as passwords or device configuration settings), the best approach is to encrypt the data using both SSH and SNMPv3 to provide encryption of data during Telnet sessions and SNMP sessions.
Q. Do Cisco Catalyst 2960 Series Switches support Cisco switch clustering technology?
A. Yes. Cisco Catalyst 2960 Series Switches can be managed using Cisco Network Assistant software, which uses Cisco switch clustering technology. Cisco Network Assistant is a PC-based network management application optimized for LANs of small and medium-sized businesses with up to 250 users. Cisco Network Assistant offers centralized management of Cisco switches, routers, and WLAN access points. It supports a wide range of Cisco Catalyst Intelligent Ethernet switches. Through a user-friendly GUI, users can configure and manage a wide array of switch functions and start the device manager of Cisco routers and Cisco wireless access points. Cisco Network Assistant is available at no cost and can be downloaded from Cisco.com.
Cisco Network Assistant provides an integrated management interface for delivering intelligent services, enabling users to manage their entire LAN with one robust tool. By bringing the simplicity of traditional LAN switching to intelligent services such as multilayer switching, QoS, multicast, and security ACLs, Cisco Network Assistant offers administrators benefits formerly reserved for only the most complex networks. Cisco Network Assistant's Guide mode leads you through the configuration of high-end features and provides enhanced online help for context-sensitive assistance. In addition, a solution wizard provides automated configuration of the switch for video streaming or video conferencing.
Cisco Network Assistant supports standards-based connectivity options such as Ethernet, Fast Ethernet, Cisco Fast EtherChannel
® technology, Gigabit Ethernet, and Gigabit EtherChannel connectivity. Because Cisco switch clustering technology is not limited by proprietary stacking modules, stacking cables, or interconnection media, Cisco Network Assistant expands the traditional cluster domain beyond a single wiring closet and lets you combine interconnections to meet specific management, performance, and cost requirements.
Cisco Catalyst 2960 Series Switches can be configured as either command or member switches in a Cisco switch cluster. Cisco Network Assistant also allows you to designate a standby or redundant command switch, which takes the commander duties should the primary command switch fail. Other important features include the ability to configure multiple ports and switches simultaneously, as well as to perform software updates across the entire cluster at once. Bandwidth graphs and link reports provide useful diagnostic information, and the topology map gives network administrators a quick view of the network status.
Q. What are the advantages of Cisco Catalyst 2960 LAN Lite switches relative to Cisco Catalyst 2950 standard image switches?
A. The Cisco Catalyst 2960 LAN Lite switches use a new hardware and software architecture that provides higher reliability and simplifies network deployments and troubleshooting. They increase deployment flexibility with dual-purpose Gigabit uplinks instead of fixed fiber ports, and the LAN Lite IOS provides more consistency with the rest of the Catalyst switching portfolio in its command-line interface. The LAN Lite IOS software provides highly secure management through SSL, SCP, and SNMPv3 and simplifies network deployments and troubleshooting with features such as TDR, IP address DCHP, and Auto-MDIX.
Q. Can I obtain a "no additional cost" Cisco IOS
® Software update for the Cisco Catalyst 2960 Series?
A. Yes. Cisco offers ongoing Cisco IOS Software updates for certain fixed-configuration and stackable Cisco Catalyst switches at no additional cost. For the life of the product, updates within the Cisco IOS Software package purchased (LAN Lite and LAN Base) will be made available.
Note that upgrades are different from updates.
