QuickSpecs
Overview
performance; this allows network operators to gather a variety of sophisticated network statistics and information for capacity
planning and real-time network monitoring purposes
Management VLAN: segments traffic to and from management interfaces, including CLI/telnet, a Web browser interface, and
SNMP
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
Device Link Detection Protocol (DLDP): monitors a cable between two switches and shuts down the ports on both ends if the
cable is broken, this prevents network problems such as loops
IPv6 management: provides future-proof networking because the switch is capable of being managed whether the attached
network is running IPv4 or IPv6; supports pingv6, tracertv6, Telnetv6, TFTPv6, DNSv6, syslogv6, FTPv6, SNMPv6, DHCPv6, and
RADIUS for IPv6
Troubleshooting: ingress and egress port monitoring enable network problem solving; virtual cable tests provide visibility into
cable problems
Connectivity
Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports
Flow control: provides back pressure using standard IEEE 802.3x, reducing congestion in heavy traffic situations
Jumbo packet support: supports up to 9216-byte frame size to improve the performance of large data transfers
High-density connectivity: provides up to 48 fixed 10/100/1000BASE-T ports in a Layer 2/Layer 3 switch
Optional 10 GbE ports: through the use of optional modules, additional 10 GbE connections are available for uplinks or high-
bandwidth server connections; flexibly supports XFP, SFP+, or CX4 local connections
IEEE 802.3at Power over Ethernet (PoE+) support: simplifies deployment and dramatically reduces installation costs by
helping to eliminate the time and cost involved in supplying local power at each access point location
Ethernet OAM (IEEE 802.3ah):
operations, administration and maintenance (OAM) management capability detects data link layer problems that occurred in the
"last mile"; monitors the status of the link between the two devices
High-bandwidth CX4 local stacking: when stacked using CX4 local stacking, achieves 12 Gbps per connection, allowing for up to
96 Gbps total stacking bandwidth (full duplex) in a resilient stacking configuration
Performance
Nonblocking architecture: up to 192 Gbps nonblocking switching fabric provides wire-speed switching with up to 143 million
pps throughput
Hardware-based wire-speed access control lists (ACLs): feature-rich ACL implementation (TCAM-based) helps provide high
levels of security and ease of administration without impacting network performance
Resiliency and high availability
Separate data and control paths: keeps control separated 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
