QuickSpecs
Overview
in a resilient stacking configuration
Performance
Nonblocking architecture
up to 192 Gb/s nonblocking switching fabric provides wirespeed switching with up to 143 million pps throughput
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
Resiliency and high availability
Separate data and control paths
separates control from services and keeps service processing isolated; increases security and performance
External redundant power supply
provides high reliability
Smart link
allows 50 ms failover between links
Spanning Tree/MSTP, RSTP
provides redundant links while preventing network loops
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
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
Layer 2 switching
16K MAC address table
provides access to many Layer 2 devices
VLAN support and tagging
supports IEEE 802.1Q with 4,094 simultaneous VLAN IDs
GARP VLAN Registration Protocol
allows automatic learning and dynamic assignment of VLANs
IEEE 802.1ad QinQ and selective QinQ
increase the scalability of an Ethernet network by providing a hierarchical structure; connect multiple LANs on a high-speed
campus or metro network
10GbE port aggregation
allows grouping of ports to increase overall data throughput to a remote device
Internet Group Management Protocol (IGMP) and Multicast
Listener Discovery (MLD) protocol snooping
controls and manages the flooding of multicast packets in a Layer 2 network
Per-VLAN Spanning Tree Plus (PVST+)
allows each VLAN to build a separate spanning tree to improve link bandwidth usage in network environments with multiple
VLANs
Layer 3 services
