(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) 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. The IP Services feature set is required.
●
IPv6 routing (RIPng, OSPFv3) is supported in hardware for maximum performance.
Advanced IP Services feature set is required for IPv6 routing.
●
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), and
PIM sparse-dense mode. 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
