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 3ComŽ 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
For optional switching fabric redundancy, the 3Com
Switch 7700R Gigabit Ethernet Redundant Switching Fabric (3C16857R) must be
used in the 8-slot version of this switch, the 3Com Switch
7700R
