Software-defined networking
• OpenFlow
Supports OpenFlow 1.3 specification to enable SDN by allowing separation of the data (packet forwarding)
and control (routing decision) paths
Quality of Service (QoS)
• Advanced classifier based QoS
Classifies traffic using multiple match criteria based on Layer 2, 3, and 4 information; applies QoS policies
such as setting priority level and rate limit to selected traffic on a per-port or per-VLAN basis
• VXLAN hardware support
VXLAN L2/L3 gateway support for up to 1024 unicast tunnels with 511 VXLAN/per tunnel.
• EVPN support
Used as overlay control plane and provides virtual connectivity between different
Layer 2/3 domains over an IP or MPLS network
• Powerful QoS feature
Creates traffic classes based on access control lists (ACLs), IEEE 802.1p precedence, IP, and DSCP or
Type of Service (ToS) precedence; supports filter, redirect, mirror, or remark; supports the following
congestion actions: strict priority (SP) queuing, weighted round robin (WRR),
weighted fair queuing (WFQ), weighted random early discard (WRED),
weighted deficit round robin (WDRR), SP+WDRR, and SP+WFQ Supports IPv6 and
fully featured L3 functionality, including RIP, OSPF, ISIS, BGP, and PIM without additional software licensing.
• Storm restraint and Broadcast control
Allows limitations of broadcast, multicast, and unknown unicast traffic rate to reduce unwanted
network broadcast traffic
Management
• Friendly port names
Allows assignment of descriptive names to ports • sFlow
Provides scalable ASIC-based wirespeed network monitoring and accounting with no impact on
network performance that allows network operators to gather a variety of sophisticated network
statistics and information for capacity planning and real-time network monitoring
• Complete session logging
Provides detailed information for problem identification and resolution
• Remote configuration and management
Enables configuration and management through a CLI located on a remote device
• Manager and operator privilege levels
Provides read-only (operator) and read/write (manager) access on CLI management interfaces
• Management VLAN
Segments traffic to and from management interfaces, including CLI/Telnet and SNMP
• Command authorization
Leverages RADIUS/HWTACACS to link a custom list of CLI commands to an individual network
administrator's login; also provides an audit trail
• Remote monitoring (RMON)
Uses standard SNMP to monitor essential network functions; supports events, alarm, history,
and statistics group plus a private alarm extension group
• Multiple configuration files
Stores easily to the flash image
• Remote intelligent mirroring
Mirrors ingress/egress ACL-selected traffic from a switch port or VLAN to a local or remote
switch port anywhere on the network
• Network Management
SNMP v1/v2c/v3, MIB-II with Traps, and RADIUS Authentication Client MIB (RFC 2618);
embedded HTML management tool with secure access
Connectivity
• Auto-MDIX
Automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports
• Packet storm protection
Protects against broadcast, multicast, or unicast storms with user-defined thresholds
• Ethernet operations, administration and maintenance (OAM)
Detects data link layer problems that occurred in the "last mile" using the IEEE 802.3ah
OAM standard; monitors the status of the link between two devices
• Flow control
Provides back pressure using standard IEEE 802.3x, reducing congestion in heavy traffic situations
• Fixed 10GbE ports
Provides four fixed SFP+ ports for a 20 GbE connection to the network without the need
for additional extension interface modules
• Jumbo packet support
Supports up to 10000-byte frame size to improve the performance of large data transfers
• IEEE 802.3at Power over Ethernet (PoE+)
Provides up to 30 W per port that allows support of the latest PoE+-capable devices such as IP phones,
wireless access points, and security cameras, as well as any IEEE 802.3af-compliant end device;
eliminates the cost of additional electrical cabling and circuits that would otherwise
be necessary in IP phone and WLAN deployments
Resiliency and High Availability
• Separate data and control paths
Separate control from services and keeps service processing isolated; increases security and performance
• Distributed Resilient Network Interconnection (DRNI)
Enables link aggregation from multiple switches to implement device-level link backup for node redundancy.
DRNI also simplifies network topology by virtualizing multiple physical devices into one logical device.
• Device Link Detection Protocol (DLDP)
Monitors link connectivity and shuts down ports at both ends if unidirectional traffic is detected,
preventing loops in STP based networks
• Intelligent Resilient Fabric (IRF)
Creates virtual resilient switching fabrics, where upto nine switches perform as a single L2 switch and
L3 router; switches do not have to be co-located and can be part of a disaster-recovery system;
servers or switches can be attached using standard LACP for automatic load balancing and
high availability; can eliminate need for complex protocols like Spanning Tree Protocol,
Equal-Cost Multipath (ECMP), or VRRP, thereby simplifying network operation
• Rapid Ring Protection Protocol (RRPP)
Connects multiple switches in a high-performance ring using standard Ethernet technology;
traffic can be rerouted around the ring in less than 50 ms, reducing the impact on traffic and applications
• Smart Link
Allows under 100ms failover between links
• Virtual Router Redundancy Protocol (VRRP)
Allows groups of two routers to dynamically back each other up to create highly available routed environments • IRF Capability
Provides single IP address management for a resilient virtual switching fabric of up to nine switches
with stacking bandwidth of up to 160 Gbps to enhance performance and reliability with
uninterrupted L2 switching and L3 forwarding., It delivers simpler, flatter, and more agile networks
by reducing the need for complex protocols.
• Spanning Tree/PVST+, MSTP, RSTP
Provides redundant links while preventing network loops
• Internal Dual Redundant Power Supply
Provides high reliability by keeping network up while delivering up to 1440 Watts of PoE+
