5000 Series Layer 2/3 Managed Data Center Switch CLI Reference Guide Receive Packets Discarded Packets Received with MAC Errors Received Packets Not Forwarded Packets Transmitted Octets • Broadcast Packets Received - Indicates the total number of received good packets that were directed to the broadcast address. Indicates the number of inbound packets that were selected for discard even though no errors preventing their delivery to a higher-layer protocol had been detected. One potential reason for discarding such packets would be to free up buffer space. • Total Packets Received with MAC Errors - Indicates the total number of inbound packets containing errors that prevented them from being delivered to a higher-layer protocol. • Jabbers Received - Indicates the number of received packets that were longer than 1518 octets (excluding framing bits, but including FCS octets), and had either a bad FCS with a nonintegral number of octets (Alignment Error) or a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error). It should be noted that this definition of a jabber is different than that provided in IEEE-802.3 section 8.2.1.5 (10BASE5) and section 10.3.1.4 (10BASE2). These documents define a jabber as any packet exceeding 20 ms. The allowed range for detecting a jabber is between 20 ms and 150 ms. • Fragments/Undersize Received - Indicates the total number of received packets that were less than 64 octets in length (excluding framing bits but including FCS octets). • Alignment Errors - - Indicates the total number of received packets that had a length (excluding framing bits, but including FCS octets) of between 64 and 1518 octets inclusive, but that also had a bad Frame Check Sequence (FCS) with a nonintegral number of octets. • FCS Errors - - Indicates the total number of received packets that had a length (excluding framing bits, but including FCS octets) of between 64 and 1518 octets inclusive, but that also had a bad Frame Check Sequence (FCS) with an integral number of octets. • Overruns - Indicates the total number of frames that were discarded as this port was overloaded with incoming packets, such that it could not keep up with the inflow. • Total Received Packets Not Forwarded - Indicates the count of valid received frames that were discarded (that is, filtered) by the forwarding process. • 802.3x Pause Frames Received - Indicates the count of MAC Control frames with an opcode indicating the PAUSE operation that were received on this interface. This count does not change when the interface is operating in half-duplex mode. • Unacceptable Frame Type - Indicates the number of frames discarded from this port because they were of an unacceptable frame type. • Total Packets Transmitted (Octets) - Indicates the total number of octets of data received on the network (excluding framing bits but including FCS octets and those in bad packets). This parameter provides a reasonable estimate of Ethernet utilization. If the user requires greater precision, the etherStatsOctets and etherStatsPkts objects should be sampled 156
