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
