FDDI Management

Concentrator configuration; connection policy; station list; concentrator performance

The FDDI menu lets you access windows to view the SmartSwitch 7000Õs FDDI conÞguration, connection policy, station list, and performance with respect to Station Management (SMT) entities present on any installed 7F06-02 Network Interface Modules.

SMT provides the system management services for the FDDI protocols, including connection management, node conÞguration, error recovery, statistics collecting, and management frame encoding. SMT is comprised of various subcomponent functions, including Connection Management (CMT) and Ring Management (RMT); one SMT entity will be present for each ring connected to a 7F06-02 module.

SMT entities installed in the SmartSwitch 7000 hub are indexed according to module and

TIP port position in the chassis. For example, if there is one 7F06-02 module installed in the chassis, its rings will be indexed 1 and 2, and the indexes will correspond to the index of the port through which they are connected; if there are two 7F06-02 modules installed, their rings will be indexed 1, 2, 3, and 4, with rings 1 and 2 corresponding to ports 1 and 2 on the module in the lowest numerical slot, and rings 3 and 4 corresponding, respectively, to ports 1 and 2 on the module in the next highest numerical slot.

The windows that provide information about the FDDI rings installed in the SmartSwitch 7000 are:

¥ConÞguration Ñ This window displays the current conÞguration and status of the ring associated with the selected SMT entity.

¥Connection Policy Ñ This window shows the types of connections between the four FDDI PHY (port) types Ñ A, B, M, and S Ñ that will be allowed by the SMT entity.
