The IntraCore 40480/40240 -10G series is a stackable Gigabit Ethernet routing switch with a choice of 24 or 48 Gigabit 10/100/1000BASE-T ports, 4 combo Gigabit Ethernet SFP slots and 2 optional 10 Gigabit Ethernet slots and 2 stacking ports on the rear panel. The IntraCore 40480/40240 series is ideal for service provider edge aggregation, Enterprise wiring closets, data center aggregation and network core deployment. It provides high performance, resilient stacking, wire speed L2 switching and L3 routing, comprehensive QoS and advanced security to deliver the scalability and resiliency to increase your company’s productivity while reducing operation cost.
Stackable Architecture
The IntraCore 40000-10G series currently includes 2 different models IC40240-10G and IC40480-10G with dual optional 10 Gigabit Ethernet uplinks. The two models provide fully non-blocking performance to fulfill the most network demands for voice and video streaming. Optional 10GBASE-XFP10 transceivers can support up to 40km for fiber uplinks. The IntraCore 40000-10G series provides two stacking ports for hardware stacking up to 320Gbps throughput. Any combination of 40000-10G series units can be stacked up to 8 units high or to a maximum of 400 ports. The stack acts as a single switching unit that is managed by a master switch, elected from one of the member switches. The master switch automatically creates and updates all the switching and optional routing tables. A working stack can add new members or delete old ones without service interruption.
High Availability
With IEEE 802.1w Rapid Spanning Tree Protocol, the IntraCore 40000-10G series provides a loop free network and redundant links to the core network with rapid convergence less than 2 second. IEEE 802.1s Multiple Spanning Tree Protocol allows a spanning-tree instance per VLAN, for Layer 2 load sharing on redundant links. The IntraCore 40000 series supports IEEE 802.3ad Link Aggregation Control Protocol (LACP). It increases bandwidth by automatically aggregating several physical links together as a logical trunk and offers load balancing and fault tolerance for uplink connections.
Adding Optional Redundant Power Supply ensures that the IntraCore 40000-10G series delivers the stable and redundant power support for today’s high-availability, mission-critical applications.
Comprehensive QoS
The IntraCore 40000-10G series offers advance QoS for marking, classification, and scheduling to deliver best-in-class performance for data, voice, and video traffic at wire speed. 8 egress queues per port enable differentiated management of up to 8 traffic types across the stack. Traffic is prioritized according to 802.1p, DSCP, IP precedence and TCP/UDP port number to provide optimal performance to real-time applications. Weight Round Robin (WRR) and strict priority ensure differential prioritization of packet flows and avoid congestion of ingress and egress queues. With bidirectional rate-limiting, per port or traffic class, the IntraCore 40000-10G series preserves network bandwidth and allows full control of network resources.
Enhanced Security
The IntraCore 40000-10G series provides enhanced security features for connectivity and access control, including ACLs, authentication and port-level security with IEEE 802.1X. Access Control Lists (ACLs) can be used to restrict access to sensitive network resources by denying packets based on L2/L3/L4 headers. SSH and RADIUS authentication protect data communication and ensure data privacy. IEEE 802.1X port-based access control ensures dynamic, port-based security and user
authentication for network access IP source guard prevents a malicious user from spoofing or taking over another user's IP address by creating a binding table between client's IP and MAC address, port, and VLAN.
Simplied Management
The IntraCore 40000-10G series supports both IPv4 & IPv6 management functions in SNMP/HTTP/Telnet/TFTP/ICMP, SSH, RADIUS/TACACS+ authentication and IPv6 QoS remapping when connecting to the switch or stack. The IntraCore 40000-10G series can be managed through by industry standard Command Line Interface (CLI) which provides a common industry look and feel to reduce training and operating costs. It also provides easy-of use Web GUI interface through a standard web browser. Four groups of RMON (history, statistic, alarms, and events) are supported for enhanced traffic management, monitoring, and analysis. Also, the IntraCore 40000-10G series can easily backup and restore Firmware and configuration files via TFTP.
Advanced IPv4 Routing
The IntraCore 40000-10G series supports hardware based IPv4 routing hardware for maximum performance. Advanced routing protocols such as RIP and OSPF provide dynamic routing by
exchanging routing information with other Layer 3 switches or routers. Multicast routing is supported under independent multicast protocol, including PIM-DM*, and PIM-SM*. DVMRP* is also supported to interconnect two multicast-enabled networks across non-multicast networks. VRRP prevents your system from failing by dynamically backing up multiple L3 switches for routing.
