MEMBERS

station_state Specifies the state of the adapter with respect to the Token Ring -- on, off, or loopback. laststationid[8] Specifies the station ID of the station that last successfully performed a PMF change, add, or remove operation. station_uid[8] Specifies the UID of the station subentity. This member is set when the subentity is created. link_state Specifies the state of the link entity. link_uid[8] Specifies the UID of the link subentity, which is set when the subentity is created. neg_trt Specifies the ANSI media access (MAC) parameter T_Neg -- the negotiated value of the token rotation timer. dup_add_flag Specifies the summary output from the duplicate address test algorithms executed by a station. upstream[6] Specifies the data link address of the nearest upstream neighbor MAC. If no upstream neighbor has been heard or if the neighbor information has timed out, this member contains the null address 00-00-00-00-00-00. oldupstream[6] Specifies the previous non-null value of the upstream member or the null address if upstream has never been non-null. upstreamdaf Specifies the upstream neighbor's duplicate address status, as reported by the NIF frame. This member is meaningful only if the upstream member is not null. downstream[6] Specifies the data link address of the nearest downstream neighbor MAC. If no downstream neighbor has been heard or if the downstream neighbor information has timed out, this member contains the null address. olddownstream[6] Specifies the previous non-null value of the downstream member or the null address if downstream has never been non-null. ring_purge_state Specifies the state of the ring purger function. frame_strip_mode Specifies the current MAC frame stripping mode. ring_error Specifies the reason code for the most recent link error or no error if no link error has occurred. loopback Specifies TRUE if the link has been set up to receive frames transmitted by it. This allows loopback testing on the ring or by using one of the physical port loopback modes. ring_latency Specifies the current ring latency as measured by the link. ring_purge_addr[8] Specifies the data link address of the currently elected ring purger. phy_state Specifies the current state of the PPC state machine for this physical port. phy_uid[8] Specifies the UID of the physical port subentity. This member is set when the subentity is created. neighbor_phy_type Specifies the type of the neighbor physical port, or unknown if there is no connection yet. phy_link_error Specifies the link error monitor current estimate of the link error rate. For an attribute value of N, the actual rate is on the order of 10^-N. broken_reason Specifies the reason why the physical port is in the broken state. A value of 0 (zero) indicates that the physical port is not in the broken state. rej_reason Specifies the reason why the physical port is in the failed or watch state. This member is not meaningful when the physical port is in any other state.

DESCRIPTION

The fddi_dna_status data structure defines the FDDI status information. This data structure is embedded in an fddiDNA_status data structure. It is used when returning counter information for the SIOCRDCTRS and SIOCRDZCTRS ioctl commands.
