These Gigabit Ethernet switches deliver quad-speed performance, 10/100/1000 and 10 Gigabit Ethernet, as well as advanced voice-enhanced features such as Power over Ethernet (PoE), auto-voice VLAN, and Quality of Service (QoS). As a result, they are ideal for enterprise organizations seeking to build a secure, convergence-enhanced campus network. Robust IPv6 support and 10 Gigabit Ethernet uplinks future-proof an enterprise network against obsolescence. Resilient Ring Protection Protocol (RRPP), Smart Link, and Intelligent Resilient Framework (IRF) deliver 50 ms switchover and carrier-class reliability. - Broadcast control: allows limitation of broadcast traffic rate to cut down on unwanted network broadcast traffic. 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 port, VLAN, or whole switch. Powerful QoS feature: supports the following congestion actions: strict priority queuing (SP), weighted round robin (WRR) queuing, and SP+WRR. Traffic policing: supports Committed Access Rate (CAR) and line rate. - Friendly port names: allow assignment of descriptive names to ports. Remote configuration and management: is available through a secure Web browser or a command-line interface (CLI). Manager and operator privilege levels: enable read-only (operator) and read/write (manager) access on CLI and Web browser management interfaces. Command authorization: leverages HWTACACS to link a custom list of CLI commands to an individual network administrator's login; also provides an audit trail. Secure Web GUI: provides a secure, easy-to-use graphical interface for configuring the module via HTTPS. - Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports. Flow control: using standard IEEE 802.3x, it provides back pressure to reduce congestion in heavy traffic situations. Ethernet OAM: provides a Layer 2 link performance and fault detection monitoring tool, which reduces failover and network convergence times. Jumbo packet support: supports up to 9216-byte frame size to improve the performance of large data transfers. 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. - 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 ensure high levels of security and ease of administration without impacting network performance. - 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 and RSTP: provide 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. - 16K MAC address table: provides access to many Layer 2 devices. VLAN support and tagging: support 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. 10 GbE port aggregation: allows grouping of ports to increase overall data throughput to a remote device.
