The Cisco Catalyst 3560-E Series access switches have one power supply slot and support the following power supplies. PoE switches require a PoE power supply. Data-only switches can operate with any of the power supplies:
Maximum power availability for converged voice and data networks is attainable when a Cisco Catalyst 3560-E Series Switch is combined with the Cisco Redundant Power System 2300 (Cisco RPS 2300) for transparent protection against internal power supply failures and an uninterruptible power supply (UPS) system to safeguard against power outages. Using the Cisco RPS 2300 to provide backup power, the Cisco Catalyst 3560-E Series Switch power supplies become hot swappable. Table 4 shows the power supply compatibility matrix.
The Cisco Catalyst 3560E-12D and the Cisco Catalyst 3560E-12SD aggregation switches have dual redundant power supplies that can be replaced, one at a time, without service interruption. Customers can choose from AC, DC, and mixed power supply options:
The Cisco Catalyst 3560-E Series can provide a lower total cost of ownership for deployments that incorporate Cisco IP phones, Cisco Aironet ® wireless LAN (WLAN) access points, or any IEEE 802.3af-compliant end device. PoE removes the need for wall power to each PoE-enabled device and eliminates the cost for additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments. The Cisco Catalyst 3560-E 24-port PoE configurations can support 24 simultaneous full-powered PoE ports at 15.4W for full powered-device support. The Cisco Catalyst 3560-E 48-port PoE configurations can support 48 simultaneous full-powered PoE ports at 15.4W when using the optional 1150W power supply. Alternatively, for deployments that do not need full PoE on all ports, a smaller power supply can be used in conjunction with Cisco Catalyst Intelligent Power Management to support 24-port and 48-port PoE configurations.
The Cisco Catalyst 3560-E Series also features Enhanced Power over Ethernet support, the capability to power a growing number of devices from a single switch port, enabling greater operational simplicity and flexibility for secure converged networks. Industry first portfolio to scale beyond 15.4W per port delivering maximum solution simplicity for 802.11n access point deployments, as well as other PoE-powered devices such as phones, monitors, digital signs, medical devices, card readers and more.
The Cisco Catalyst 3560-E 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 3560-E Series Switches at the same time. The failed power supply can be swapped out while the switch is being powered up by the Cisco RPS 2300. The Cisco Catalyst 3560E-12D and 3560E-12SD aggregation switches don't support the RPS, they provide redundancy and switch uptime with dual redundant modular power supplies.
Primary Features and Benefits
Ease of Use: Deployment
The Cisco Catalyst 3560-E offers ease of use features such as Cisco Smartports, which enable fast and easy configuration of advanced Cisco Catalyst intelligent capabilities, encapsulating years of Cisco networking expertise. Cisco Smartports macros offer a set of verified feature 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 minimal effort and expertise.
Other ease of use features include:
• Dynamic Host Configuration Protocol (DHCP) autoconfiguration of multiple switches through a boot server eases switch deployment.
• Automatic QoS (AutoQoS) simplifies QoS configuration in voice-over-IP (VoIP) networks by issuing interface and global switch commands to detect Cisco IP phones, classify traffic, and help enable egress queue configuration.
• Autonegotiation on all ports automatically selects half- or full-duplex transmission mode to optimize bandwidth.
• Dynamic Trunking Protocol (DTP) facilitates 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.
• Automatic media-dependent interface crossover (MDIX) automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight-through) is installed.
• Unidirectional Link Detection Protocol (UDLD) and Aggressive UDLD allow unidirectional links caused by incorrect fiber-optic wiring or port faults to be detected and disabled on fiber-optic interfaces.
Availability and Scalability
The Cisco Catalyst 3560-E Series is equipped with a robust set of features that allow for network scalability and higher availability. This is achieved through IP routing as well as a complete suite of Spanning Tree Protocol enhancements aimed to maximize availability in a Layer 2 network. Enhancements to the standard Spanning Tree Protocol, such as Per-VLAN Spanning Tree Plus (PVST+), Uplink Fast, and Port Fast, as well as innovations such as Flexlink, maximize network uptime.
• Flexlink provides link redundancy with convergence time less than 100ms without Spanning Tree Protocol. A pair of interfaces configured as primary and backup links can load balance traffic based on VLAN. IEEE 802.1s/w Rapid Spanning Tree Protocol (RSTP) and Multiple Spanning Tree Protocol (MSTP) provide rapid spanning-tree convergence independent of spanning-tree timers and also offer the benefit of Layer 2 load balancing and distributed processing.
• Per-VLAN Rapid Spanning Tree (PVRST+) allows rapid spanning-tree reconvergence on a per-VLAN spanning-tree basis, without requiring the implementation of spanning-tree instances.
• Cisco Hot Standby Router Protocol (HSRP) is supported to create redundant, failsafe routing topologies.
• Switch-port Autorecovery (Errdisable) automatically attempts to reactivate a link that is disabled because of a network error.
High-Performance IP Routing
Cisco Express Forwarding hardware routing architecture delivers extremely high-performance IP routing in the Cisco Catalyst 3560-E Series Switches.
• Basic IP unicast routing protocols (Static, Routing Information Protocol Version 1 [RIPv1], and RIPv2, RIPng, EIGRP stub) are supported for small-network routing applications.
• Advanced IP unicast routing protocols (OSPF, EIGRP, and BGPv4) are supported for load balancing and constructing scalable LANs. IPv6 routing (OSPFv3 and EIGRPv6) is supported in hardware for maximum performance. The IP Services feature set is required.
• Equal-cost routing facilitates Layer 3 load balancing and redundancy.
• Policy-based routing (PBR) allows superior control by facilitating flow redirection regardless of the routing protocol configured. The IP Services feature set is required.
• HSRP provides dynamic load balancing and failover for routed links, up to 32 unique HSRP links supported per unit. The group number can be reused for each VLAN configured in the switch.
• Protocol Independent Multicast (PIM) for IP multicast routing is supported, including PIM sparse mode (PIM-SM), Source Specific Multicast (SSM), PIM dense mode (PIM-DM), PIM sparse-dense mode and Source Specific Multicast (SSM). The IP Services feature set is required.
• Web Control Caching Protocol (WCCPv2) enables Wide Area Acceleration Services (WAAS), resulting in improved application response time and conservation of WAN bandwidth.
• Fallback bridging forwards non-IP traffic between two or more VLANs. The IP Services feature set is required.
Superior Quality of Service
The Cisco Catalyst 3560-E Series offers Gigabit Ethernet speed with intelligent services that keep everything flowing smoothly, even at 10 times the normal network speed. Industry-leading mechanisms for marking, classification, and scheduling deliver superior performance for data, voice, and video traffic, all at wire speed.
Following are some of the QoS features supported in the Cisco Catalyst 3560-E Series Switches:
• 802.1p class of service (CoS) and differentiated services code point (DSCP) field classification is provided, using marking and reclassification on a per-packet basis by source and destination IP address, MAC address, or Layer 4 TCP/UDP port number.
• Cisco control-plane and data-plane QoS ACLs on all ports help ensure proper marking on a per-packet basis.
• Eight egress queues per port help enable differentiated management of different traffic types across the switch. Four queues are user configurable and four are reserved for system use.
• Shaped Round Robin (SRR) scheduling helps ensure differential prioritization of packet flows by intelligently servicing the ingress queues and egress queues.
• 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.
• The Cisco committed information rate (CIR) function provides bandwidth in increments as low as 8 Kbps.
• Rate limiting is provided based on source and destination IP address, source and destination MAC address, Layer 4 TCP/UDP information, or any combination of these fields, using QoS ACLs (IP ACLs or MAC ACLs), class maps, and policy maps.
• Up to 64 aggregate or individual policers are available per Fast Ethernet or Gigabit Ethernet port.
Advanced Security
The Cisco Catalyst 3560-E Series supports a comprehensive set of security features for connectivity and access control, including ACLs, authentication, port-level security, and identity-based network services with 802.1x and extensions. This set of comprehensive features not only helps prevent external attacks, but defends the network against "man-in-the-middle" attacks, a primary concern in today's business environment. The switch also supports the Network Admission Control (NAC) security framework.
• DHCP Snooping prevents malicious users from spoofing a DHCP server and sending out invalid addresses. This feature is used by other primary security features to prevent a number of other attacks such as ARP poisoning.
• Dynamic ARP Inspection (DAI) helps ensure user integrity by preventing malicious users from exploiting the insecure nature of the ARP protocol.
• IP source guard prevents a malicious user from spoofing or taking over another user's IP address by creating a binding table between the client's IP and MAC address, port, and VLAN.
• Private VLANs restrict traffic between hosts in a common segment by segregating traffic at Layer 2, turning a broadcast segment into a nonbroadcast multi-access-like segment.
• Private VLAN Edge provides security and isolation between switch ports, which helps ensure that users cannot snoop on other users' traffic.
• Uncast RPF feature helps mitigate problems caused by the introduction of malformed or forged (spoofed) IP source addresses into a network by discarding IP packets that lack a verifiable IP source address.
• IEEE 802.1x allows dynamic, port-based security, providing user authentication.
• IEEE 802.1x with VLAN assignment allows a dynamic VLAN assignment for a specific user regardless of where the user is connected.
• IEEE 802.1x with voice VLAN permits an IP phone to access the voice VLAN irrespective of the authorized or unauthorized state of the port.
• IEEE 802.1x and port security are provided to authenticate the port and manage network access for all MAC addresses, including that of the client.
• IEEE 802.1x with an ACL assignment allows for specific identity-based security policies regardless of where the user is connected.
• IEEE 802.1x with guest VLAN allows guests without 802.1x clients to have limited network access on the guest VLAN.
• Web authentication for non-802.1x clients allows non-802.1x clients to use an SSL-based browser for authentication.
• Multi-Domain Authentication allows an IP phone and a PC to authenticate on the same switch port while placing them on appropriate voice and data VLANs.
• MAC Auth Bypass (MAB) for voice allows third-party IP phones without an 802.1x supplicant to get authenticated using their MAC address.
• Cisco security VLAN ACLs on all VLANs prevent unauthorized data flows from being bridged within VLANs.
• Cisco standard and extended IP security router ACLs define security policies on routed interfaces for control-plane and data-plane traffic. IPv6 ACLs can be applied to filter IPv6 traffic.
• Port-based ACLs for Layer 2 interfaces allow security policies to be applied on individual switch ports.
• Secure Shell (SSH) Protocol, Kerberos, and Simple Network Management Protocol Version 3 (SNMPv3) provide network security by encrypting administrator traffic during Telnet and SNMP sessions. SSH Protocol, Kerberos, and the cryptographic version of SNMPv3 require a special cryptographic software image because of U.S. export restrictions.
• Bidirectional data support on the Switched Port Analyzer (SPAN) port allows the Cisco intrusion detection system (IDS) to take action when an intruder is detected.
• TACACS+ and RADIUS authentication facilitates centralized control of the switch and restricts unauthorized users from altering the configuration.
• MAC Address Notification allows administrators to be notified of users added to or removed from the network.
• Port Security secures the access to an access or trunk port based on MAC address.
• Multilevel security on console access prevents unauthorized users from altering the switch configuration.
• Bridge protocol data unit (BPDU) guard shuts down Spanning Tree PortFast-enabled interfaces when BPDUs are received to avoid accidental topology loops.
• Spanning Tree Root Guard (STRG) prevents edge devices not in the network administrator's control from becoming Spanning Tree Protocol root nodes.
• IGMP filtering provides multicast authentication by filtering out nonsubscribers and limits the number of concurrent multicast streams available per port.
• Dynamic VLAN assignment is supported through implementation of VLAN Membership Policy Server client capability to provide flexibility in assigning ports to VLANs. Dynamic VLAN facilitates the fast assignment of IP addresses.
Intelligent Power over Ethernet (PoE) Management
The Cisco Catalyst 3560-E PoE models support Cisco IP phones and Cisco Aironet wireless LAN (WLAN) access points, as well as any IEEE 802.3af-compliant end device. The Cisco Catalyst 3560-E-48PD can support 48 simultaneous full-powered PoE ports at 15.4W with the 1150W power supply.
• Cisco Discovery Protocol version 2 allows the Cisco Catalyst 3560-E Series Switch to negotiate a more granular power setting when connecting to a Cisco powered device, such as IP phones or access points, than what is provided by IEEE classification.
• Per Port power consumption command allows customer to specify maximum power setting on an individual port.
