Table 12-3. Alphabetical List and Descriptions of Token Ring Error Counters

Token Ring Counter	Description
Abort Delimiter	Records events where a reporting Ring Station encounters recover-
	able internal errors, forcing it to transmit an Abort Delimiter frame.
AC Error	Records events where the reporting Ring Station’s nearest active
	upstream neighbor could not set the address recognized bits or frame
	copied bits in the newly transmitted frame after copying the bits on the
	last frame received.
Burst Error	Records events where the reporting Ring Station encounters signal
	transition or signal error on the Token Ring physical medium
Frame Copy	Records when a reporting Ring Station copies a frame containing the
	Ring Station’s own (duplicate) address.
Frequency	Records events where the reporting Ring Station attempts to receive a
	frame containing an improper ring-clock frequency.
Internal Error	Records events where the reporting Ring Station encounters a recov-
	erable internal error.
Line Error	Records events where the reporting Ring Station’s checksum process
	detects an error in a received data frame or token that the Ring Station
	transmitted.
Lost Frame	Records events where a reporting Ring Station generates a frame to a
	specific address and does not receive the returned frame.
Token Error	Records events where the Token Ring Active Monitor does not detect
	a ring token.
