VIP Master. Joseph W. Hall of Fame Expert. Leo Laohoo. VIP Community Legend. VIP Advisor. In response to Leo Laohoo. Cisco multigigabit technology allows you to achieve bandwidth speeds from 1 Gbps through 10 Gbps over traditional Category 5e Cat 5e cabling or above. Cisco multigigabit technology offers significant benefits for a diverse range of speeds, cable types, and PoE power.
The benefits can be grouped into three different areas:. The supported speeds are Mbps, 1 Gbps, 2. The Cisco Catalyst Series adds new mini switches to the existing family of switches. You can avoid replacing the cabinets or mounting the switch at an angle and as a result reduce downtime to the network.
These switches enable the same uniform wired-wireless policy enforcement, application visibility, flexibility, application optimization, and superior resiliency as the existing switches.
These switches support stacking and can stack with each other or the existing switches using the same Cisco StackWise technology. The mini and use the same software and thus can be deployed and managed using the same policies, configuration, and so on as the existing switches. Some use cases for the mini are the following:. Many small branches and satellite offices where there are few employees do not have larger wiring closets because of space constraints.
A typical office like this has smaller cabinets and would need a switch that can serve few employees, provide PoE support, can manage wired-wireless networks, and applies the same consistent policies as a bigger branch or office. Because of its shallow depth and lower noise, these switches are ideally suited for classrooms or confined areas.
A typical retail outlet needs to serve customers at multiple sales points, each with a POS machine, access points, phone, printer, video display with network, and some PoE powering.
These retail outlets connect to the access router that connects them to the outside network and typically need switches that fit in shallow depth cabinets. With this, Cisco has pioneered a host of rich capabilities such as high availability based on stateful switchover SSO on stacking, granular QoS, security, and Flexible NetFlow FNF across wired and wireless in a seamless fashion.
The single console port for command-line interface CLI management reduces the number of touch points to manage for wired plus wireless services, thereby reducing network complexity, simplifying network operations, and lowering the TCO to manage the infrastructure. Converged wired plus wireless not only improves wireless bandwidth across the network but also the scale of wireless deployment. Each port Cisco Catalyst provides 40 Gbps of wireless throughput 20 Gbps on the port model.
This wireless capacity increases with the number of members in the stack. This makes sure that the network can scale with current wireless bandwidth requirements, as dictated by IEEE Additionally, the Cisco Catalyst distributes the wireless controller functions to achieve better scalability. In this mode the switch is capable of terminating the CAPWAP tunnels from the access points and providing wireless connectivity to wireless clients.
Maintaining wireless client databases and configuring and enforcing security and QoS policies for wireless clients and access points can be enforced in this mode. No additional license on top of IP Base is required to operate in the mobility agent mode. The mobility controller mode can be enabled on the switch CLI. IP Base license level is required when the Cisco Catalyst switch is acting as the mobility controller. With mobility agents located in the wiring closets providing 40 Gbps of wireless per switch n x 40 Gbps for a stack of n switches and mobility controllers managing some of the central wireless functions, the converged access-based wireless deployment provides best-in-class scalability for wireless and significantly improved wireless throughput.
This helps identify users and user traffic flows in order to identify potential attackers and take corrective action at the access layer before the attack penetrates further into the network. This is achieved using FNF, which monitors every single flow entering and exiting the switch stack for wired and wireless users. The switch has advanced wired plus wireless QoS capabilities. The switch manages wireless bandwidth using unprecedented hierarchical bandwidth management starting at the per-access-point level and drilling further down to per-radio, per-service set identification SSID , and per-user levels.
This helps manage and prioritize available bandwidth between various radios and various SSIDs enterprise, guest, and so on within each radio on a percentage basis.
The switch is also capable of automatically allocating equal bandwidth among the connected users within a given SSID. This makes sure that all users within a given SSID get a fair share of the available bandwidth while being connected to the network. In addition to these capabilities, the switch is able to do class of service CoS or differentiated services code point DSCP based queuing, policing, shaping, and marking of wired plus wireless traffic.
This enables users to create common policies that can be used across wired plus wireless traffic. The Cisco Catalyst provides a rich set of security features for wired plus wireless users. Features such as IEEE The Cisco Catalyst supports an optional stacking module that is based on the Cisco StackWise technology.
Cisco StackWise technology is built on the highly successful industry-leading StackWise technology, which is a premium stacking architecture. StackWise has a stack bandwidth of Gbps. The active switch automatically elects a standby switch within the stack. If the active switch fails, the standby switch assumes the role of the active switch and continues to the keep the stack operational. Access points continue to remain connected during an active-to-standby switchover.
A working stack can accept new members or delete old ones without service interruption. StackWise creates a highly resilient single unified system of up to nine switches, providing simplified management using a single IP address, single Telnet session, single CLI, auto-version checking, auto-upgrading, auto-configuration, and more. See Figure 4. Software services supported on the Cisco Catalyst Series Switches can be classified into five broad categories:.
Cisco Catalyst Smart Operations are a comprehensive set of capabilities that simplify LAN deployment, configuration, and troubleshooting. In addition to adaptive, always-on technologies such as StackWise, Cisco Catalyst Smart Operations enable zero-touch installation and replacement of switches, fast upgrade, and 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. Using EEM, customers can adapt the behavior of their network devices to align with their business needs. This feature requires the IP Base feature set. This feature requires the IP Services feature set.
Automatic software version checking and updating help ensure that all stack members have the same software version. Cisco Catalyst Series Switches, designed and engineered by Cisco, provide optimum power-saving, EEE, low-power operations for industry best-in-class power management and power consumption capabilities. The Cisco Catalyst ports are capable of reduced power modes so that ports not in use can move into a lower power utilization state. Other efficient switch operation features are:.
Per-port PoE power sensing measures actual power being drawn, enabling more intelligent control of powered devices.
Organizations may choose to turn off access point radios to reduce power consumption during off-peak hours. The integrated wireless LAN controller avoids the deployment of additional devices in the network. Cisco Prime infrastructure provides day 0 and ongoing provisioning, ongoing monitoring and maintenance, configuration templates, and device and user degree views and serves as the FNF collector for user traffic views using the Cisco Prime Assurance Manager module.
Cisco Catalyst Series Switches support advanced security features including but not limited to:. This feature is used by other primary security features to prevent a number of other attacks such as ARP poisoning.
Increased network availability through proactive blocking of known threats. Borderless networks enable enterprise mobility and business-grade video services. The true borderless experience is enabled by the following feature sets in the Cisco Catalyst Series Switches:. In addition to StackWise, the Cisco Catalyst Series supports high-availability features including but not limited to the following:.
Stacked units behave as a single spanning-tree node. Limited static routing with the LAN Base feature set. Equal-cost routing facilitates Layer 3 load balancing and redundancy across the stack. The IP Base feature set is required. The IP Services feature set is required.
The Cisco Catalyst Series offers Gigabit Ethernet speed with intelligent services that keep traffic flowing smoothly, even at 10 times the normal network speed. Industry-leading mechanisms for cross-stack marking, classification, and scheduling deliver superior performance for data, voice, and video traffic, all at wire speed. Fair sharing across the users within an SSID makes sure that no single user is starved because of other heavy-hitting users. Fair sharing is automatically enabled for wireless at user level as well as SSID level.
Weighted tail drop WTD provides congestion avoidance at the ingress and egress queues before a disruption occurs. Strict priority queuing helps ensure that the highest priority packets are serviced ahead of all other traffic. Up to aggregate policers are available per switch.
Cisco IOS Software FNF is the next generation in flow visibility technology, allowing optimization of the network infrastructure, reducing operation costs, and improving capacity planning and security incident detection with increased flexibility and scalability.
The Cisco Catalyst provides optimized application visibility with FNF across wired plus wireless. The switch is capable of 48, flow entries on port models and 24, flow entries on port models across wired and wireless.
