Installation and Operation Manual Chapter 6 Monitoring and Diagnostics
ACE-3105, ACE-3205 Ver. 5.2 Monitoring Performance 6-15
Parameter Description Possible Values
RX FCS errors Number of received frames that did not
pass the FCS check Numerical
RX congestion
dropped Number of frames that were dropped due
to lack of buffers.
This may be caused by attempting to send
traffic towards the Ethernet connection at
a rate higher than the ATM transmission
rate.
Numerical
TX correct frames Number of successfully transmitted frames Numerical
TX correct bytes Number of successfully transmitted bytes Numerical
TX single collisions Number of successfully transmitted frames
for which transmission was inhibited by
one collision exactly. Valid only in
half-duplex mode. Numerical
TX multiple collisions Number of successfully transmitted frames
for which transmission was inhibited by
more than one collision. Valid only in
half-duplex mode. Numerical
TX deferred transmit Number of frames for which the first
transmission attempt is delayed, due to a
busy line. Valid only in half-duplex mode. Numerical
TX late collision Number of times in which a collision was
detected on a particular interface after the
first 512 bit cycles of a transmitted packet. Numerical
Port number The Ethernet port for which the statistics
is displayed. 1
Viewing the E1/T1 Port Statistics
The E1/T1 port statistics refer to the physical status of the E1/T1 traffic reaching
the ACE-3105, ACE-3205 unit from other E1/T1 devices.
³
To view the current E1/T1 connection statistics:
• From the Port menu (see Figure 6-13
), select E1 (or T1).
The connection statistics of Port 1 is displayed by default.
Table 6-13
explains the different statistic parameters.
