Interfaces
145
• Out Discards (Ethernet/Wireless-Slot A/B): The number of error-free outbound packets chosen to be discarded to
prevent their being transmitted. One possible reason for discarding such a packet could be to free up buffer space.
• Out Errors (Ethernet/Wireless-Slot A/B): The number of outbound packets that could not be transmitted because of
errors.
• Out Non-unicast Packets (Ethernet/Wireless-Slot A/B): The total number of packets that higher-level protocols
requested be transmitted to a non-unicast (i.e., a subnetwork-broadcast orsubnetwork-multicast) address, including
those that were discarded or not sent.
• Out Octets (bytes) (Ethernet/Wireless-Slot A/B): The total number of octets transmitted out of the interface, including
framing characters.
• Out Unicast Packets (Ethernet/Wireless-Slot A/B): The total number of packets that higher-level protocols requested
be transmitted to a subnetwork-unicast address, including those that were discarded or not sent.
• Output Queue Length (Ethernet/Wireless-Slot A/B): The length of the output packet queue (in packets).
• Physical Address (Ethernet): The interface's address at the protocol layer immediately below the network layer in the
protocol stack.
• Received Fragment Count (Wireless-Slot A/B): The number of successfully received Data or Management MAC
Protocol Data Units (MPDUs).
• Retry Count (Wireless-Slot A/B): The number of packets successfully transmitted after one or more retransmissions.
• Single Collision Frames (Ethernet): The number of successfully transmitted frames for which transmission is
inhibited by exactly one collision
• Speed (Ethernet/Wireless-Slot A/B): An estimate of the interface's current bandwidth in bits per second.
• SQE Test Errors (Ethernet): The number of times that the Signal Quality Error (SQE) Test Error message is
generated by the physical layer signalling (PLS) sublayer.
• Successful RTS Count (Wireless-Slot A/B): The number of times a Clear to Send (CTS) is received in response to
an Request to Send (RTS).
• Transmitted Fragment Count (Wireless-Slot A/B): The number of transmitted fragmented packets.
• Transmitted Frame Count (Wireless-Slot A/B): This number of successfully transmitted packets.
• Type (Ethernet/Wireless-Slot A/B): The type of interface, distinguished according to the physical/link protocol(s)
immediately below the network layer in the protocol stack.
• Unknown Protocols (Ethernet/Wireless-Slot A/B): The number of packets received that were discarded because of
an unknown or unsupported protocol.
• WEP Undecryptable Count (Wireless-Slot A/B): The number of undecryptable WEP frames received.
