	buffers. Note that this counter reports the number of
	times frames were dropped for lack of buffering, not the
	number of frames dropped. Although this is considered a
	non-isolating error, you can assume that the adapter
	reporting the error is at fault. If the error occurs
	frequently, you may want to consider replacing the
	reporting station’s NIC card.
Frame Copied Errors	The number of frames addressed to the associated station
	that had the A (Address Recognized Indicator) bits
	already set to 1 when the station received the frame. This
	indicates that an electrical line disturbance has corrupted
	the token, or that there is a duplicate address on the ring
	(either a station with a shared administratively assigned
	address, or a transparent bridge that has set the bit).
Token Errors	The number of times the associated station, while acting
	as the active monitor, has detected an error that required
	the transmission of a token (either because a frame was
	lost, or a token or frame has recirculated the ring). Note
	that this error can only be reported by a station that is, or
	was previously, the active monitor for the ring.
Frequency Errors	The number of times the associated station detected that
	the incoming signal’s frequency differed from the
	expected frequency by more than allowed by the IEEE
	802.5 standard (.6%). Frequency is measured by an
	on-board crystal oscillator on each network interface.
	This could indicate an error in the reporting station’s
	oscillator, the Active Monitor, or any station between the
	two; it happens more often on 16 Mbps rings than on 4
	Mbps rings, and can also be a symptom of too many
	stations on the ring. When a station detects this
	condition, it will begin a monitor contention process to
	select a new Active Monitor.

Changing the Station Labels

Initially, each station in the ring map is labelled by MAC address

; addresses are displayed in Canonical format (reverse bit order).

You can change the map’s station labels to reﬂect one of the following:

Board/Port/Drop – This label displays each station’s board and port index, as well as its administratively assigned drop number (if one has been assigned).
