Lowering the total cost of ownership and simplifying network operation are primary reasons for using the Cisco Catalyst switches. These features include:. CiscoWorks LMS is a suite of powerful management tools that simplify the configuration, administration, monitoring, and troubleshooting of Cisco networks. It integrates these capabilities into a world-class solution for improving the accuracy and efficiency of your operations staff, while increasing the overall availability of your network.

It supports more than different device types, providing:. PoE eliminates the need for wall power outlets for each PoE-enabled device and significantly reduces the cost for additional electrical cabling that would otherwise be necessary in IP phone and WLAN deployments.

The 24 port switch models provide Class 3 PoE or Prioritization of traffic is critical to many network services such as voice, video and wireless and the Catalyst Cisco Catalyst LAN Lite Switches help ensure that network traffic congestion is avoided allowing business critical applications to perform without degradation. The Cisco Catalyst LAN Lite Switches support hardware based QoS with no performance degradation including 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 SRR algorithm helps ensure differential prioritization and helps ensure excellent network performance with line rate traffic loads. Multicast is a key capability available in the Catalyst switches that can efficiently deliver high bandwidth applications across the network and optimize network performance saving bandwidth.

It supports distributed applications and enables next generation multimedia applications including: Corporate Communications, E-learning, IP Video Surveillance, High Definition Video, and distribution of data to desktops in a scalable, reliable and efficient manner. Cisco Catalyst LAN Lite Switches support layer 2 Multicast traffic and use protocols to allow customer to deploy streaming video applications in the network and benefit from bandwidth saving provided.

The Cisco Catalyst LAN Lite Switches support security features that can help your business protect important information, keep unauthorized people off the network, guard privacy, and maintain uninterrupted operation. The Cisco Identity-Based Networking Services IBNS solution provides authentication, access control, and security policy administration to secure network connectivity and resources.

Using the This setup allows your IT department to enable strong security policies without compromising user mobility, and with minimal administrative overhead. You can use port security to limit access on an Ethernet port based on the MAC address of the device to which it is connected. You also can use it to limit the total number of devices plugged into a switch port, thereby protecting the switch from a MAC flooding attack as well as reducing the risks of rogue wireless access points or hubs.

You can use the MAC Address Notification feature to monitor the network and track users by sending an alert to a management station so that your network administrators know when and where users entered the network. Alternatively, you can configure a local username and password database on the switch itself. Fifteen levels of authorization on the switch console and two levels on the web-based management interface allow you to give different levels of configuration capabilities to different administrators.

The Cisco Catalyst LAN Lite Series is equipped with a robust set of features that allow for network scalability and higher availability with a complete suite of Layer 2 protocols including Spanning Tree Protocol enhancements aimed maximizing availability in a Layer 2 network.

I have this problem too. All forum topics Previous Topic Next Topic. Leo Laohoo. VIP Community Legend. In response to Leo Laohoo. I'm using Cisco Network Assistant 6. In response to rabah Each queue is dedicated to handling specific protocol packets and is assigned a priority level. For example, STP, routed, and logged packets are sent to three different control plane queues, which are prioritized in corresponding order, with STP having the highest priority.

Each queue is allocated a certain amount of processing time based on its priority. The processing-time ratio between low-level functions and high-level functions is allocated as 1-to Therefore, the control plane logic dynamically adjusts the CPU utilization to handle high-level management functions as well as punted traffic up to the maximum CPU processing capacity.

Basic control plane functions, such as the CLI, are not overwhelmed by functions such logging or forwarding of packets. If this message appears, check that there is network connectivity between the switch and the ACS. If this happens, enter the no auto qos voip cisco-phone interface command on all interface with this configuration to delete it.

Then enter the auto qos voip cisco-phone command on each of these interfaces to reapply the configuration. From the Settings window, choose Automatically.

Click OK to exit the Internet Options window. If you are not using the default method of authentication the enable password , you need to configure the HTTP server interface with the method of authentication used on the switch. Configure the HTTP server interface for the type of authentication that you want to use. The device manager uses the HTTP protocol the default is port 80 and the default method of authentication the enable password to communicate with the switch through any of its Ethernet ports and to allow switch management from a standard web browser.

You should write down the port number through which you are connected. Use care when changing the switch IP information. The Bug Search Tool BST , which is the online successor to Bug Toolkit, is designed to improve the effectiveness in network risk management and device troubleshooting.

The BST allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data such as bug details, product, and version. The tool has a provision to filter bugs based on credentials to provide external and internal bug views for the search input.

Available Languages. Download Options. Updated: May 31, We recommend 1 GHz. Internet Explorer 6. Cluster Compatibility You cannot create and manage switch clusters through the device manager.

When creating a switch cluster or adding a switch to a cluster, follow these guidelines: When you create a switch cluster, we recommend configuring the highest-end switch in your cluster as the command switch. If you are managing the cluster through Network Assistant, the switch with the latest software should be the command switch. The standby command switch must be the same type as the command switch. For example, if the command switch is a Catalyst C switch, all standby command switches must be Catalyst C switches.

Deciding Which Files to Use The upgrade procedures in these release notes describe how to perform the upgrade by using a combined tar file. To download software, follow these steps: Step 1 Use Table 3 to identify the file that you want to download. Step 2 Download the software image file: a. Installation Notes Use these methods to assign IP information to your switch: The Express Setup program , as described in the switch getting started guide.

The CLI-based setup program, as described in the switch hardware installation guide. The DHCP-based autoconfiguration, as described in the switch software configuration guide.

Manually assigning an IP address, as described in the switch software configuration guide. Limitations and Restrictions You should review this section before you begin working with the switch. The problem is observed only when the switch is receiving frames. CSCed When port security is enabled on an interface in restricted mode and the switchport block unicast interface command has been entered on that interface, MAC addresses are incorrectly forwarded when they should be blocked The workaround is to enter the no switchport block unicast interface configuration command on that specific interface.

This does not affect switch functionality. CSCsj When you enter the boot host retry timeout global configuration command to specify the amount of time that the client should keep trying to download the configuration and you do not enter a timeout value, the default value is zero, which should mean that the client keeps trying indefinitely.

However, the client does not keep trying to download the configuration. CSCsk When authorization and accounting are enabled on the switch and you use the interface range command to change the configuration on a range of interfaces, the change might cause high CPU utilization and authentication failures.

CSCuv, CSCuv When a logging discriminator is configured and applied to a device, memory leak is seen under heavy syslog or debug output. The rate of the leak is dependent on the quantity of logs produced. In extreme cases, the device may crash. As a workaround, disable the logging discriminator on the device. CSCur, CSCur We recommend that you configure the access-session interface-template sticky timer timer-value command at the global or interface configuration mode, and not within the template.
