IBM SC30-3681-08 Lobe wire faults, Removes received, Burst errors, Inputs dropped, Token errors

Using the GWCON Interface Command

Lobe wire faults

Displays the number of times the network detects an open or short circuit in the cable between the interface and the wiring concentrator.

Removes received

Displays the number of times the interface receives a remove ring station MAC frame request and removes itself from the network.

Burst errors

Displays the number of times the interface detects the absence of transitions for ®ve half-bit times between the start delimiter (SDEL) and the end delimiter (EDEL) or between the EDEL and the SDEL.

Inputs dropped

Displays the number of times an interface in repeat mode recognizes a frame addressed to it but has no buffer space available to copy the frame.

Token errors

The token errors counter increments when the active monitor detects a token protocol with any of the following errors:

The MONITOR_COUNT bit of token with nonzero priority equals one.

The MONITOR_COUNT bit of a frame equals one. No token or frame is received within a 10-ms window.

The starting delimiter/token sequence has a code violation in an area where code violations must not exist.
