Redundant Power System
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
