3com Switch 7700 7-Slot Gigabit Ethernet Fabric Module network switch component 3Com®

Gigabit Ethernet Switch Fabric for the Switch 7700 The Switch Fabric Module is the core of the 3Com Switch 7700 system. The Switch Fabric performs route calculation and provides all Layer 3 switching functionality. It also performs Layer 2 switching between interface modules and where on-board Layer 2 switching is not possible. Based on the address-forwarding table, the hardware performs line-speed switching of Layer 2 / Layer 3 data packets. VLANs, link aggregation, QoS traffic classification and prioritization, and ACLs (Access Control Lists) are also supported by the hardware. In addition to switching functions, the Switch Fabric Module performs control and management functions for the system. The management channel performs such functions as initialization and configuration of the system, data packet learning, protocol processing, and network management. It also provides environmental monitoring, software upgrade and interface module control. The Switch Fabric Module is essential for 3Com® Switch 7700 system operation and must be installed into the top slot to connect to the chassis backplane. It is included in the 3Com Switch 7700R 8-slot Gigabit Starter Kit, 3C16852, and 3Com Switch 7700 7-slot Gigabit Starter Kit, 3C16850. Network protocols supported: TCP/ IP, ARP/Proxy ARP, DHCP Multicast protocol support: GARP/GVRP/GMRP, IGMP, PIM-DM/SM IP routing: RIP (V1/V2), OSPF V2 Higher bandwidth and added reliability through link aggregation to create virtual connections. Logical segmentation of the network supported by VLAN. Multiple overlapping tagged VLANs support aggregated links and extension throughout the network Improved network security and bandwidth availability with static routes; default route is used to shorten time for route selection. Quality of Service (QoS) functions: traffic classification, DiffServ service, IEEE 802.1p service, traffic bandwidth limitation, and traffic bandwidth guarantee System configuration: English CLI through console port for local or remote Telnet or SNMP v3 access. Plain ASCII text configuration files enable faster setup of multiple similar systems. RMON and SMON support. System maintenance: status indicators for the module and each interface, hardware watchdog to protect against system software failure, hierarchical user authority, operation log and online help functions, alarm level management and alarm filtering functions, query of system status. Debugging and tracing functions provide real-time monitoring of system operational status System test and diagnosis: power-on self-test and command test; current status of system modules, cards, ports, chips and tasks; query memory space, address table, packet buffer, flash memory capacity, queue and current message number; supports loopback test at different levels from card to port. Software upgradability: multiple software upgrade modes via Switch Fabric Console
