| Features and Benefits |
| Connectivity |
| 10-GbE optical/copper media flexibility |
offers SR/LR/ER optical and CX4 copper connectivity in a single 2-port X2 Interface Module |
| Performance |
| Large switching capacity |
provides up to 320 Gbps bandwidth |
| Wire-speed 100/1000 design |
assures non-blocking packet forwarding on all Gigabit ports |
| Jumbo frames |
on Gigabit and 10-Gigabit ports, allow high-performance remote backup and disaster-recovery services (up to 4 ports per module on Gigabit modules) |
| Distributed processing architecture |
results in better system utilization and performance |
| Resiliency and high availability |
| Modular, distributed software architecture |
individual restartable processes yield enhanced overall system availability and supportability |
| Optional redundancy |
| Redundant switch fabric |
provides rapid (‹ 0.2 sec.), automatic active-to-standby module failover |
| Redundant management |
provides automatic failover from the active management module to the standby management module |
| Redundant power supply |
provides uninterrupted power |
| Multiple Spanning Trees (IEEE 802.1s) |
provides efficient high link availability in multiple VLAN environments by allowing multiple coincident spanning trees; includes support of Spanning Tree Protocol (IEEE 802.1D) and Rapid Spanning Tree Protocol (IEEE 802.1w) |
| Automatic routing switch failover |
provides hot-standby redundancy using standards-based VRRP (Virtual Router Redundancy Protocol) |
| Port trunking |
for higher switch-to-switch throughput and link-level redundancy, with support for standards-based link aggregation (IEEE 802.3ad); supports up to 80 trunks, each with up to 8 links (ports) per trunk; trunking across modules is supported |
| Hot-swappable modules |
permit modules and mini-GBICs to be added or swapped without interrupting the network |
| Layer 2 switching |
| IP multicast snooping and data-driven IGMP v2/v3 |
automatically prevents flooding of IP multicast traffic |
| Layer 3 routing |
| Standards-based IP routing |
provides routing of IP at media speed; supports static routes, RIP, RIPv2, and OSPF with ECMP |
| 100,000 IP address routing table |
enables large network deployments |
| Security |
| Hardware-based wire-speed access control lists |
feature-rich ACL implementation (based on port, MAC, protocol, IP address, TCP/UDP port number) to help ensure high levels of security and ease of administration without impacting network performance |
| VLAN support and tagging |
support complete IEEE 802.1Q (1,024 active VLANs across 4,096 VLAN IDs) and 180 routable VLAN interfaces |
| Secure Shell (SSHv2) |
encrypts all transmitted data for secure, remote command-line interface (CLI) access over IP networks |
| Switch management logon security |
can require either RADIUS or TACACS+ authentication for secure switch CLI logon |
| Processor self-protection architecture |
provides protection against denial-of-service attacks |
| Quality of Service (QoS) |
| Traffic prioritization based on IEEE 802.1p and Diffserv (TOS) |
allows real-time traffic classification into 11 traffic classes mapped to 5 queues and up to 3 levels of RED drop precedence, providing rich QoS capabilities |
| Class of Service (CoS) |
sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), L3 protocol, TCP/UDP port number, source port, and DiffServ |
| Guaranteed minimum bandwidth |
per-port, per-queue guaranteed minimums allow traffic to receive the guaranteed minimum bandwidth during times of congestion |
| Ease of use |
| Dual bootable flash images |
provide independent primary and secondary OS files for backup while upgrading; multiple flash images can be stored on flash for archival purposes |
| Port mirroring |
enables traffic on a port to be simultaneously sent to a network analyzer for monitoring |
| Industry-leading warranty |
|
One-year next-business-day advance replacement (available in most countries), with extensions available |
