●
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.
