Chapter 28 Troubleshooting LRE Statistics Table 28-1 Ethernet Port Statistics (continued) Statistic Type Multicast Frames Broadcast Frames Discarded Frames Alignment Errors FCS Errors Undersize frames Minimum size frames Oversize Frames Control frames Pause frames Unknown opcode Length out of range Symbol errors False carrier valid, too small valid, too large invalid, too small invalid, too large Explanation The total number of well-formed multicast frames received by a port. It excludes frames received with errors, with unicast or broadcast destination addresses, or with oversized or undersized frames. Also excluded are frames discarded or without a destination. The total number of well-formed broadcast frames received by a port. It excludes frames received with errors, with unicast or multicast destination addresses, or with oversized or undersized frames. Also excluded are frames discarded or without a destination. The total number of frames discarded because of insufficient receive bandwidth or receive buffer space or because the forwarding rules stipulate that they not be forwarded. The total number of frames received with alignment errors. It includes all the frames received with both an FCS error and a nonintegral number of bytes. The total number of frames received with FCS errors. It excludes undersized frames with FCS errors. The total number of frames received that were less than 64 octets long (excluding framing bits, but including FCS octets) and were otherwise well formed. The total number of frames received that were 64 octets long (excluding framing bits, but including FCS octets) and were otherwise well formed. The total number of frames received of more than 1518 bytes that have good FCS values. Incremented for each MAC control frame (pause and unsupported) received. Incremented for each MAC pause control frame received. Incremented for every non-pause MAC control frame received. Incremented for each frame received where the 802.3 length field in the packet did not match the number of bytes actually received. This counter is not incremented if the length field is not a valid 802.3 length but is an ethernet packet type. Incremented each time a valid carrier was present and at least one invalid data symbol was received. Incremented each time a false carrier is detected during idle. The event is reported along with the statistics generated on the next received frame. Only one false carrier condition can be generated and reported between frames. Incremented for each received frame that was valid but had a size that was smaller than the minimum sized frame (of length 64 bytes). Incremented for each received frame that was valid but had a size that was larger than the maximum sized frame (of length 1518 bytes). Incremented for each received frame that was invalid and had a size that was smaller than the minimum sized frame (of length 64 bytes). Incremented for each received frame that was invalid and had a size that was larger than the maximum sized frame (of length 1518 bytes). 78-14982-01 Catalyst 2950 Desktop Switch Software Configuration Guide 28-3
