FDDI Management

Concentrator M Ports

This ﬁeld displays the number of Master (M) ports on the device that are associated with the selected SMT entity. A Master port is a port that provides a connection for Single Attachment Station (SAS) devices to the FDDI network. The 9A128-01 does not support M ports, so this ﬁeld will always display 0.

Concentrator Non-M Ports

This ﬁeld display the number of non-Master ports (A, B, or S ports) on the device that are associated with the selected SMT entity. The 9A128-01 supports only two FDDI ports: the backplane A and B ports that supply each device’s connection to the FDDI FNB backplane.

Number of MACs

The number of Media Access Control entities present on the device associated with the selected SMT entity. For the 9A128-01, this number will be 1.

MAC Path

Indicates the conﬁguration of the MAC in respect to the logical ring, as determined by the Connection Management (CMT) portion of SMT. CMT controls the establishment of a media attachment to the FDDI network, the connections with other nodes in the ring, and the internal conﬁguration of the various entities within a node. CMT provides the link conﬁdence test, and speciﬁes a Link Error Monitor (LEM) which monitors active links on a per-link basis to ensure that failing links are detected and, if required, removed from the network. Possible values are:

•Primary indicates that the MAC is inserted into the primary path of the currently used FNB ring.

•Secondary indicates that the MAC is inserted into the secondary path of the currently used FNB ring.

•Local means that the MAC is not inserted into a primary or secondary path of a dual ring, but may be connected to one or more other nodes. This is not a valid value for the 9A128-01.

•Isolated means that the MAC has no connection to the ring or other concentrator ports.

•Not Available means that there is no MAC on the FDDI ring associated with the selected SMT entity. Again, this state will not occur for the 9A128-01.

•Unknown means that device ﬁrmware cannot determine the MAC path.

•? indicates that SPECTRUM Element Manager cannot determine the MAC path.

Ring Conﬁguration

The current conﬁguration of the MAC and physical layers of the A and B ports.
