●
Spanning Tree Root Guard (STRG) prevents edge devices not in the network administrator’s control from
becoming Spanning Tree Protocol root nodes.
●
Wireless end-to-end security offers CAPWAP-compliant DTLS encryption to make sure of encryption
between access points and controllers across remote WAN/LAN links.
Resiliency
Borderless networks enable enterprise mobility and business-grade video services. Industry’s first unified network
(wired plus wireless) location services enable tracking of mobile assets and the users of those assets for both
wired plus wireless devices. The true borderless experience is enabled by the following feature sets in the Cisco
Catalyst 3850 Series Switches:
●
High availability
●
High-performance IP routing
●
Superior QoS
High Availability
In addition to StackWise-480 and StackPower, the Cisco Catalyst 3850 Series supports high-availability features
including but not limited to the following:
●
Cross-Stack EtherChannel provides the ability to configure Cisco EtherChannel technology across different
members of the stack for high resiliency.
●
Flexlink provides link redundancy with convergence time less than 100ms.
●
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. Stacked units behave as a single spanning-tree node.
●
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.
●
Switch-port autorecovery (Err-disable) automatically attempts to reactivate a link that is disabled because
of a network error.
High-Performance IP Routing
The Cisco Express Forwarding hardware routing architecture delivers extremely high-performance IP routing in the
Cisco Catalyst 3850 Series Switches:
●
IP unicast routing protocols (static, Routing Information Protocol Version 1 [RIPv1], and RIPv2, RIPng,
Enhanced Interior Gateway Routing Protocol [EIGRP] stub) are supported for small-network routing
applications with the IP Base feature set. Limited static routing with the LAN Base feature set. Equal-cost
routing facilitates Layer 3 load balancing and redundancy across the stack.
●
Advanced IP unicast routing protocols (Open Shortest Path First [OSPF], EIGRP, Border Gateway Protocol
Version 4 [BGPv4], and Intermediate System-to-Intermediate System Version 4 [IS-ISv4]) are supported for
load balancing and constructing scalable LANs. IPv6 routing (OSPFv3, EIGRPv6) is supported in hardware
for maximum performance. OSPF for routed access is included in the IP Base image. The IP Services
feature set is required for full OSPF, EIGRP, BGPv4, and IS-ISv4.
