High Performance
- Large Switching Capacity: with up to 320 Gbps bandwidth
- Wirespeed Design: assures non-blocking packet forwarding on all ports
- Jumbo frames: on Gigabit and 10-Gigabit ports, allows high-performance remote backup and disaster recovery services (up to 4 ports per module on Gigabit modules)
High Availability
- Optional Redundancy:
- Redundant switch fabric provides automatic failover for the active switch fabric module to the standby fabric module
- Redundant management provides automatic failover for the active management module to the standby management module
- Redundant power supply provides uninterrupted power
- Spanning Tree Protocol (IEEE 802.1D): provides redundant links while preventing network loops
- 802.1w Rapid Convergence Spanning Tree Protocol*: increases network uptime through faster recovery from failed links
- 802.1s Multiple Spanning Tree*: provides high link availability in multiple VLAN environments by allowing multiple spanning trees
- 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); support 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
IP Routing
- Standards based IP routing: provides routing of IP at media speed; supports static routes, RIP, RIPv2, and OSPF with ECMP
- 100K IP address routing table: enables large network deployments
Quality of Service
- IP multicast snooping (data-driven IGMP)*: automatically prevents flooding of IP multicast traffic
- Traffic prioritization based on 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 Quality of Service capabilities
- Class of Service (CoS): update egress 802.1p or IP DSCP based on ingress port 802.1p, IP Diffserv, or policy
- Guaranteed minimum bandwidth: per-port, per-queue guaranteed minimums allow traffic to receive guaranteed minimum bandwidth during times of congestion
Security
- Hardware-based wire-speed access control lists: feature-rich ACL implementation (based on port, MAC, protocol, IP address, TCP/UDP port number) to ensure high levels of security and ease of administration without impacting network performance
- VLAN support and tagging: support complete 802.1Q (1024 active VLANs across 4096 VLAN IDs) and 180 Routable VLAN Interfaces
- Secure Shell (SSHv2): encrypts all transmitted data for secure CLI remote access over IP networks
- Switch management logon security: can require either RADIUS or TACACS+ authentication for secure switch CLI logon
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
- Port mirroring: enables traffic on a port to be simultaneously sent to a network analyzer for monitoring
