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
Hardware-based wirespeed access control lists (ACLs)
help provide high levels of security and ease of administration without impacting network performance with a feature-rich
TCAM-based ACL implementation
Nonblocking architecture
delivers up to 224 Gb/s of wire-speed switching with a nonblocking switching fabric and up to 167 million pps throughput
Resiliency and high availability
Separate data and control paths
separates control from services and keeps service processing isolated; increases security and performance
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
Intelligent Resilient Framework (IRF)
creates virtual resilient switching fabrics, where two or more 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 the 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 50 ms 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
Dual flash images
provides independent primary and secondary operating system files for backup while upgrading
Multiple configuration files
allow multiple configuration files to be stored to a flash image
IEEE 802.1AB Link Layer Discovery Protocol (LLDP)
facilitates easy mapping using network management applications with LLDP automated device discovery protocol
allows ingress and egress port monitoring enabling network problem solving; virtual cable tests provide visibility into cable
IPv6 management
future-proofs networking, as the switch is capable of being managed whether the attached network is running IPv4 or IPv6;
supports pingv6, tracertv6, Telnetv6, TFTPv6, DNSv6, and ARPv6
Layer 2 switching
GARP VLAN Registration Protocol
