Cisco StackWise Technology for Stackable Resiliency Cisco StackWise® technology is a stacking architecture optimized for Gigabit Ethernet. This technology is designed to respond to additions, deletions, and redeployment while maintaining constant performance. Cisco StackWise technology unites up to nine individual switches in a single logical unit, using special stack-interconnect cables and stacking software. The individual switches can be any combination of Cisco Catalyst 3750, 3750 v2, and 3750-E Series Switches. The stack behaves as a single switching unit that is managed by a master switch, chosen from one of the member switches. The master switch automatically creates and updates all the switching and optional routing tables. A working stack can accept new members or delete old ones without service interruption.
Cisco StackWise stacking creates a 32-Gbps switch interconnection. Stacking does not require user ports. Up to 9 units can be stacked together for a maximum of 468 10/100 ports. Additional port combinations can be created by stacking together the Cisco Catalyst 3750 v2, 3750, and 3750-E Series Switches.
Cisco Catalyst 3750 v2 Series Software The Cisco Catalyst 3750 v2 Series can be purchased with the IP Base or IP Services license preinstalled. The IP Base license offers advanced quality of service (QoS), rate limiting, access control lists (ACLs), and basic static and Routing Information Protocol (RIP) and OSPF routing functions. The IP Services license provides a richer set of enterprise-class features, including advanced hardware-based IP unicast and IP multicast routing as well as policy-based routing (PBR). The Advanced IP Services license, which includes IPv6 routing and IPv6 ACL support, is now included in the IP Services license. Upgrade licenses are available to upgrade a switch from the IP Base license to the IP Services license.
Configurable Cisco IOS Software The Cisco Catalyst 3750 v2 Series can be preconfigured with a specific Cisco IOS Software release at the time of ordering. This option eliminates the need to reload a specific Cisco IOS Software release during deployment, thereby reducing deployment time and cost. The Cisco IOS Software release to be preloaded can be selected from a list of supported Cisco IOS Software releases, including the crypto version.
Cisco EnergyWise The Cisco Catalyst 3750 v2 Series supports Cisco EnergyWise, which is a technology that enables monitoring, reporting, and management of energy consumption by end devices that are EnergyWise enabled. This technology enables companies to reduce their energy costs and carbon footprints. EnergyWise features enable you to:
• Discover all Cisco EnergyWise enabled devices on the network • Monitor and report power consumption by these devices • Implement business rules to control power to these end devices Power over Ethernet The Cisco Catalyst 3750 v2 Series can provide a lower total cost of ownership (TCO) for deployments that incorporate Cisco IP Phones, Cisco Aironet® wireless LAN (WLAN) access points, or any IEEE 802.3af-compliant end device. 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 Cisco Catalyst 3750 v2 24-port PoE switch can support Class 3 PoE or 15.4 watts (W) of PoE power on all 24 ports. Taking advantage of Cisco Catalyst Intelligent Power Management, the Cisco Catalyst 3750 v2 48-port PoE configurations can deliver the necessary power to support 24 ports at 15.4W, 48 ports at 7.7W, or any combination in between. Maximum power availability for a converged voice and data network is attainable when a Cisco Catalyst 3750 v2 Series Switch is combined with the Cisco RPS 2300 for protection against internal power supply failures and an uninterruptible power supply (UPS) system to safeguard against power outages.
Redundant Power System The Cisco Catalyst 3750 v2 Series access switches support the new generation of Cisco RPS 2300, which increases availability in a converged data, voice, and video network by providing transparent power backup to two of six attached Cisco Catalyst 3750 v2 Series Switches at the same time. The Cisco Catalyst 3750 v2 Series Switches are capable of reverting to their internal power supply without any service interruption. In addition, the Cisco RPS 2300 can be managed by a Cisco Catalyst 3750 v2 Series Switch that is connected to it.
Primary Features and Benefits Ease of Use and Deployment The Cisco Catalyst 3750 v2 Series offers several ease-of-use features, which enable fast and easy configuration of advanced Cisco Catalyst capabilities. These features include:
• Cisco SmartPorts simplify the configuration of advanced Cisco Catalyst capabilities, encapsulating years of Cisco networking expertise. Cisco SmartPort macros offer a set of verified, pretested, recommended switch port configurations or templates per connection type that are easy to apply, enabling users to consistently and reliably configure essential security, IP telephony, availability, QoS, and manageability features with little effort and expertise. • Cisco Auto-SmartPorts automatically execute SmartPort macros based on the end-device type, such as IP phones, desktop computers, and WLAN access points. • Cisco Express Setup simplifies initial configuration with a web browser, eliminating the need for more complex terminal emulation programs and command-line interface (CLI) knowledge. • IEEE 802.3af and Cisco prestandard PoE support comes with automatic discovery to detect a Cisco prestandard or IEEE 802.3af endpoint and provide the necessary power without any user configuration. • Dynamic Host Configuration Protocol (DHCP) autoconfiguration of multiple switches through a boot server eases switch deployment. • DHCP AutoInstall simplifies the deployment of a large number of switches by automatically downloading a specified Cisco IOS Software image and a configuration file from a Trivial File Transfer Protocol (TFTP) server. This feature can be used to implement an automated, or zero-touch, deployment. • DHCP Port-Based Allocation allows you to allocate the same IP address for a specified port. The feature allows persistent allocation of IP addresses to specified network devices. • Cisco IOS Embedded Event Manager (EEM) is a powerful and flexible tool for management and automation. This feature can be used to monitor network events and program automatic actions based on these network events. Policies can be defined through the CLI or through Tool Command Language (TCL) scripts and can be used in a variety of scenarios, such as automatic backup of a configuration file at a specified time or the triggering of an alert when traffic congestion crosses a specified threshold. Cisco IOS EEM requires the IP Services license. • Configuration Replace and Rollback simplifies configuration management by allowing you to roll back configuration changes. This feature allows you to replace a configuration file with a saved configuration file without a switch reload; up to 14 configuration files can be saved. • Automatic QoS (Auto-QoS) simplifies QoS configuration in voice-over-IP (VoIP) networks by sending interface and global switch commands to detect Cisco IP Phones, classify traffic, and enable egress queue configuration. • Autosensing on each 10/100 port detects the speed of the attached device and automatically configures the port for 10- or 100-Mbps operation, easing switch deployment in mixed 10- and 100-Mbps environments. • Autonegotiation on all ports automatically selects half- or full-duplex transmission mode to optimize bandwidth. • Dynamic Trunking Protocol (DTP) helps enable dynamic trunk configuration across all switch ports. • Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel groups or Gigabit EtherChannel groups to link to another switch, router, or server. • Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with devices that conform to IEEE 802.3ad. This feature is similar to Cisco EtherChannel technology and PAgP. • DHCP Server enables a convenient deployment option for the assignment of IP addresses in networks that do not have a dedicated DHCP server. • DHCP Relay allows a DHCP relay agent to broadcast DHCP requests to the network DHCP server. • IEEE 802.3z-compliant 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX, 1000BASE-T, and coarse wavelength-division multiplexing (CWDM) physical interface support through a field-replaceable SFP module provides exceptional flexibility in switch deployment. • The default configuration stored in flash memory helps ensure that the switch can be quickly connected to the network and can pass traffic with little user intervention. • Automatic medium-dependent interface crossover (Auto-MDIX) automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight through) is installed on a 10/100 port. • Time Domain Reflectometry (TDR) helps diagnose and resolve cabling problems on copper Ethernet ports. |
