Show/Monitor/List Commands Command Reference Counters Displays the accumulated counters for the Ethernet, LAT and TCP/IP protocols. The first seven lines of counters apply to Ethernet traffic in general. The fields and error counters are explained below. Table 12-6: Counters Display Fields Field Meaning of Counter Frames sent with xx collisions Bad Destination Buffer Unavailable Data Overrun Failure Reasons Gives a rough estimate of Ethernet traffic. In general, higher traffic levels cause more collisions. Counts packets that the Server received for an unsupported protocol. These are generally multicasts or broadcast packets; frequently seen unknown protocols include LAVC and DECnet routing. Counts packets lost due to an inability to allocate receive space on the part of either the Ethernet controller (Net Buffer) or the operating system (Sys Buffer). Shows packets that were dropped due to the controller's inability to transfer Ethernet data to memory. Generally, this happens only under unusually heavy load conditions. Packets dropped by the Ethernet hardware are retransmitted by the LAT or TCP/IP protocol handlers. Values represent a combination of the error reasons that have occurred since the counters were last zeroed. The values for failure reasons are expressed in hexadecimal codes and represent binary masks of all of the errors that have occurred since the counters were last zeroed. There are different numbers of significant digits for each field; they represent the following: Format: 0 0 h h (0 = unused, h = hex digit) For example, a value of 000C in the Recv Failure Reasons represents a nonaligned packet and FIFO overrun because 000C hex= 12 decimal= 0000 0000 0000 1100 binary. The binary bits are numbered right to left starting with zero, so in this example, bits 2 and 3 are set. 12-70
