202 CHAPTER 17: VIEWING STATISTICS ■ Received Bytes (Octets) - Displays the number of octets received on the interface since the device was last refreshed. This number includes bad packets and FCS octets, but excludes framing bits. ■ Received Packets - Displays the number of packets received on the interface, including bad packets, Multicast and broadcast packets, since the device was last refreshed. ■ Broadcast Packets Received - Displays the number of good broadcast packets received on the interface since the device was last refreshed. This number does not include Multicast packets. ■ Multicast Packets Received - Displays the number of good Multicast packets received on the interface since the device was last refreshed. ■ CRC & Align Errors - Displays the number of CRC and Align errors that have occurred on the interface since the device was last refreshed. ■ Undersize Packets - Displays the number of undersized packets (less than 64 octets) received on the interface since the device was last refreshed. ■ Oversize Packets - Displays the number of oversized packets (over 9216 octets) received on the interface since the device was last refreshed. ■ Fragments - Displays the number of fragments (packets with less than 64 octets, excluding framing bits, but including FCS octets) received on the interface since the device was last refreshed. ■ Jabbers - Displays the total number of received packets that were longer than 9216 octets. This number excludes frame bits, but includes FCS octets that had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a non-integral octet (Alignment Error) number. The field range to detect jabbers is between 20 ms and 150 ms. ■ Collisions - Displays the number of collisions received on the interface since the device was last refreshed. ■ Frames of 64 Bytes - Displays the number of 64-byte frames received on the interface since the device was last refreshed. ■ Frames of 65 to 127 Bytes - Displays the number of 65 to 127 byte frames received on the interface since the device was last refreshed.
