28 S&C Instruction Sheet 1041-550
IntelliLINK
Figure 12. TROUBLESHOOTING: Various Counters screen.
The switch control counts and records errors and events associated with the interrupt
service routine, the data link layer, and the application layer. The counts are stored in
non-volatile memory, but may be cleared if necessary.
To clear the counts in both pages of this screen:
a. If you want to save the count information on the screen, generate a report.
IMPORTANT: Once you clear the counts and statistics, the data cannot be recovered.
b. Click on Clear All in the upper right corner of the screen. This causes all counters
and statistics to return to 0, except the Min 2way which clears to the maximum value
of 255.
The fields on these screens are grouped into four categories: Receiver Interrupt Counts,
Application Layer Counts, Data Link Layer Counts, and Communication Statistics.
These are errors associated with the communications interrupt routine. If applicable, the
data for each port is shown separately.
Bad CRC
This field shows the number of failed CRC calculations on incoming packets.
Simul. Rcv/Xmt
This field shows the number of times the receiver and transmitter were enabled simulta-
neously.
