●
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 3650 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.
●
Policy-based routing (PBR) allows superior control by facilitating flow redirection regardless of the routing
protocol configured. Virtual routing and forwarding (VRF)-Lite enables a service provider to support two or
more VPNs, with overlapping IP addresses. The IP Services feature set is required.
●
Protocol-independent multicast (PIM) for IP multicast routing is supported, including PIM sparse mode
(PIM-SM), PIM dense mode (PIM-DM), PIM sparse-dense mode, and source-specific multicast (SSM).
The IP Services feature set is required.
●
IPv6 addressing is supported on interfaces with appropriate show commands for monitoring and
troubleshooting.
Superior QoS
The Cisco Catalyst 3650 Series offers Gigabit Ethernet speed with intelligent services that keep traffic flowing
smoothly, even at 10 times the normal network speed. Industry-leading mechanisms for cross-stack marking,
classification, and scheduling deliver superior performance for data, voice, and video traffic, all at wire speed.
The following are some of the QoS features supported in the Cisco Catalyst 3650 Series Switches:
●
Granular wireless bandwidth management and fair sharing use Cisco’s proven Cisco IOS Software and
UADP ASIC technology to provide hierarchical bandwidth management at line rate (per access point, per
radio, per SSID, per client-based policies). Fair sharing across the users within an SSID makes sure that
no single user is starved because of other heavy-hitting users. Fair sharing is automatically enabled for
wireless at user level as well as SSID level.
●
802.1p CoS and 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 Transmission Control Protocol/User
Datagram Protocol (TCP/UDP) port number.
