PoE MIB provides proactive visibility into power usage for monitoring and troubleshooting. Switches exchange speed, duplex, and power settings with end devices such as IP phones.
Integrated Service Delivery with QoS and Multicast: 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.
Key features for integrated service delivery include: Voice VLAN simplifies telephony installations by keeping voice traffic on a separate VLAN for easier administration and troubleshooting. Standard Four egress queues per port enable differentiated management of up to four traffic types. Shaped Round Robin SRR scheduling helps ensure differential prioritization of packet flows by intelligently servicing the ingress and egress queues.
Weighted tail drop WTD provides congestion avoidance at the ingress and egress queues before a disruption occurs. Strict priority queuing guarantees that the highest-priority packets are serviced ahead of all other traffic.
Internet Group Management Protocol Version 3 IGMPv3 snooping provides fast client joins and leaves of multicast streams and limits bandwidth-intensive video traffic.
IGMP filtering provides multicast authentication by filtering out no subscribers and limits the number of concurrent multicast streams available per port. Security 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. Key security features include: IEEE IEEE MAC address notification allows administrators to be notified of users added to or removed from the network.
