All software feature sets support advanced security, QoS, and management features. A special file contained in the switch, called a license file, is examined by Cisco IOS Software when the switch is powered on. License types can be changed, or upgraded, to activate a different feature set. StackWise technology was designed to respond to additions, deletions, and redeployment while maintaining constant performance. The stack behaves as a single switching unit that is managed by a master switch elected from one of the member switches. The master switch automatically creates and updates all the switching and optional routing tables.

Energy Efficient Ethernet Cisco EnergyWise Technology Cisco EnergyWise is an innovative architecture, added to fixed configuration switches, promoting companywide sustainability by reducing energy consumption across an entire corporate infrastructure and affecting more than 50 percent of global greenhouse gas emissions created by worldwide building infrastructure, a much greater effect than the 2 percent generated by the IT industry.
Cisco EnergyWise enables companies to measure the power consumption of network infrastructure and network-attached devices and manage power consumption with specific policies, reducing power consumption to realize increased cost savings, potentially affecting any powered device. EnergyWise encompasses a highly intelligent network-based approach to communicate messages that measure and control energy between network devices and endpoints.
The network discovers Cisco EnergyWise manageable devices, monitors their power consumption, and takes action based on business rules to reduce power consumption. EnergyWise uses a unique domain-naming system to query and summarize information from large sets of devices, making it simpler than traditional network management capabilities.
Efficient Switch Operation Cisco Catalyst X Series Switches, designed and engineered by Cisco, provide optimum power saving, low power operations for industry best-in-class power management, and power consumption capabilities. The Cisco Catalyst X ports are capable of reduced power modes so that ports not in use can move into a lower power utilization state. StackPower lets customers to simply add one extra power supply in any switch of the stack and provide either power redundancy for any of the stack members or simply add more power to the shared pool.
Per port power consumption command allows customers to specify maximum power setting on an individual port. Per port PoE power sensing measures actual power being drawn, enabling more intelligent control of powered devices.
The PoE MIB provides proactive visibility into power usage and allows customers to set different power-level thresholds. During peak work hours, most wired client devices use their network connections with infrequent bursts. The normal EEE operation is well suited to this behavior. During off-peak times the client devices may use sleep or hibernate modes.
At this time the network interface can be completely inactive and able to be woken on demand by remote request. Prior to the EEE standard, it was a common practice for client devices such as personal computers and servers to save power during sleep states by renegotiating the Ethernet link to a lower speed.
With EEE capability, PCs and other "sleep oriented" devices can achieve power savings similar to the speed downshift while allowing a much faster transition back to the active state.
In addition to adaptive, always on technologies such as StackWise and StackPower, Cisco Catalyst Smart Operations enable zero touch installation and replacement of switches, fast upgrade, as well as ease of troubleshooting with reduced operational cost. Smart Install utilizes dynamic IP address allocation and the assistance of other switches to facilitate installation providing transparent network plug and play. Cisco Auto Smartports provide automatic configuration as devices connect to the switch port, allowing auto detection and plug and play of the device onto the network.
Cisco Smart Configuration provides a single point of management for a group of switches and in addition adds the ability to archive and backup configuration files to a file server or switch allowing seamless zero touch switch replacement. Using EEM, customers can adapt the behavior of their network devices to align with their business needs.
This feature requires IP Base feature set. This feature requires IP Services feature set. Stacking master configuration management and Cisco StackWise technology helps ensure that all switches are automatically upgraded when the master switch receives a new software version.
Automatic software version checking and updating help ensure that all stack members have the same software version. Autonegotiation on all ports automatically selects half- or full-duplex transmission mode to optimize bandwidth. Automatic media-dependent interface crossover MDIX automatically adjusts transmit and receive pairs if an incorrect cable type crossover or straight-through is installed. Switching Database Manager SDM templates for access, routing, and VLAN deployment allow the administrator to easily maximize memory allocation to the desired features based on deployment-specific requirements.
Smart Multicast, with Cisco StackWise Plus technology, allows the Cisco Catalyst X Series to offer greater efficiency and support for more multicast data streams such as video by putting each data packet onto the backplane only once. Per-port broadcast, multicast, and unicast storm control prevents faulty end stations from degrading overall systems performance.
Layer 2 traceroute eases troubleshooting by identifying the physical path that a packet takes from source to destination. Cisco Network Assistant A PC-based network management application designed for small and medium-sized business SMB networks with up to users, Cisco Network Assistant offers centralized network management and configuration capabilities.
Cisco Network Assistant uses Cisco Smartports technology to simplify both initial deployment and ongoing maintenance. This application also features an intuitive GUI where users can easily apply common services across Cisco switches, routers, and access points, such as: Configuration management.
