Transcend? network management

All SuperStack II switches are managed by 3Com Transcend? network management and control solutions. Transcend solutions give you end-to-end visibilityand control over all devices in your network with two levels of management: 1) technologies, such as embedded SmartAgent? software and RMON, within 3Com devices throughout the network, and 2) centralized highly automated applications at the network center for monitoring, configuring, and troubleshooting all devices in the network.

Ships with 3Com Transcend Network Supervisor

This PC-based application provides powerful, yet easy-to-use network management tuned to the needs of small-to-medium enterprises. Network devices are automatically discovered and network activity and stress monitored through an intuitive graphical interface focused on the tasks and information all managers need to take control of their network.

Web-based management

Manage your switches with any Web browser, either through direct or dial-up connection or across the LAN. This delivers ease of use and accessibility to network management personnel and reduces in-service costs, but still with full security.

Roving Analysis Port (RAP)

RAP allows a network analyzer attached to any unit in a stack to monitor any of the switch ports or virtual LANs (VLANs) in the stack. It also minimizes the time required for problem determination and resolution and maximizes switch uptime, thereby lowering your cost of ownership.

RMON support

Transcend softwares powerful combination of RMON (Remote Monitoring, a superset of SNMP MIB II) and embedded SmartAgent software reduces the processing burden on your management station, minimizes network traffic, and saves time by automatically monitoring and analyzing your network. RMON tells you at a glance how the network is performing and who is using it the most. And Transcend software gives you the added benefit of RMON features in your network without the processing and memory costs usually associated with RMON. See the At-a-Glance RMON Support table for details on RMON groups supported by SuperStack II switches.

CoS can be defined simply as a method for prioritizing various traffic types. 3Com switches can support two methods of enabling CoS on Ethernet networks. The first method is IEEE 802.1D (incorporating 802.1p), which enables eight levels of prioritization; and the second method is 3Coms innovative PACE? technology, which allows the user to specify certain applications as high priority. A hardware feature, dual queues, is used to exploit these traffic prioritization schemes; the dual queues functionrequired for CoSwill automatically enable a second port buffer for high-priority traffic thereby allowing the traffic to bypass lower priority data for faster processing within the switch.

Broadcast traffic control

Traditional Ethernet switches suffer from the threat of broadcast storms that can potentially bring networks to a halt. However, all SuperStack II switches can be configured with broadcast storm protection to limit the number of broadcast packets allowed to be forwarded by each port. This allows the SuperStack II switches to offer the security of broadcast storm protection normally associated with a router while also providing the protocol independence of a switch.

Spanning tree

Support for the industry-standard IEEE 802.1D spanning tree protocol is provided as an alternative to resilient links. This protects against network loops and can be used to provide redundant network paths.

Port trunking

Port trunking establishes backbone links by treating multiple parallel links as a single network pipe. Trunking also provides link redundancy; traffic on any failed link comprising a network trunk automatically switches over to the other links in the trunk.

VLANs allow PCs, workstations, and other resources, including printers and file servers, to be organized into logical, broadcast domains so that only devices within the same domain can communicate with each other. 3Com switches allow users to implement VLANs on their network using one of two schemes: IEEE 802.1Q, including GVRP, which enables the auto-learning of VLANs, or 3Coms VLT. Both methods allow for the configuration of VLANs based on ports and/or MAC addresses for maximum flexibility and security. For 802.1Q VLANs, a port on a switch can be assigned to a VLAN; all other switches learn about that VLAN when the switches automatically communicate that knowledge via the GVRP protocol.

Layer 3 switching

Layer 3 switching is the implementation of routing protocols in leading-edge ASIC technology. Routing performance is dramatically and cost effectively boosted to enable the widespread deployment of intranets (IP-based networking).
