- Small Buffers – number of buffers currently assigned to the port
(see RX_Q Overflows below).
- RX_Q Overflows – number of packets dropped by the port due to
a lack of buffers. After a reboot, the ATX tries to automatically
re-allocate the Small Buffers among the ports so the total number
of RX_Q Overflows is minimized.
- Ring State – either
number of intermediate RMT states that are possible while the
ring is in transition.
- Port Config – normally
wrap or be isolated when there are ring breaks. If the two FDDI
cables have been incorrectly connected
as the port status.
Note: All counter values are reset to zeros if the ATX is rebooted or if the
module housing that port is halted and restarted.

4.2 STATISTICS

The ATX collects statistics applicable to I/O modules and ports and stores
them in the following MIBs: the portion of MIB-2, the bridge MIB, the
FDDI MIB, and the SMC enterprise MIB. You can access the stored
information using an SNMP-based NMS. Refer to your NMS
documentation for instructions. The following statistics are available for
the 3F00-01 and 3F55-01:
• Module Status and Statistics
• Port Status and Statistics
- General Port Status and Statistics
- Port Receive Statistics
- Port Transmit Statistics
- Port Error Status and Statistics
• 3F00-01/3F55-01 Port SMT Status
• 3F00-01/3F55-01 Port MAC Status
