Monitoring
Interfaces
• Ethernet Chipset (Ethernet): Identifies the chipset used to realize the interface.
• Excessive Collisions (Ethernet): The number of frames for which transmission fails due to excessive collisions.
• Failed ACK Count (Wireless-Slot A/B): The number of times an acknowledgment (or ACK) is not received when
expected.
• Failed Count (Wireless-Slot A/B): The number of packets not transmitted successfully due to too many transmit
attempts.
• Failed RTS Count (Wireless-Slot A/B): The number of times a Clear to Send (CTS) is not received in response to a
Request to Send (RTS).
• FCS Error (Wireless-Slot A/B): The number of Frame Check Sequence errors detected in received MAC Protocol
Data Units (MPDUs).
• FCS Errors (Ethernet): The number of frames received that are an integral number of octets in length but do not pass
the Frame Check Sequence check.
• Frames Too Long (Ethernet): The number of frames received that exceed the maximum permitted frame size.
• In Discards (Ethernet/Wireless-Slot A/B): The number of error-free inbound packets that were chosen to be
discarded to prevent their being deliverable to a higher-layer protocol. One possible reason for discarding such a
packet could be to free up buffer space.
• In Errors (Ethernet/Wireless-Slot A/B): The number of inbound packets that contained errors preventing them from
being deliverable to a higher-layer protocol.
• In Non-unicast Packets (Ethernet/Wireless-Slot A/B): The number of non-unicast (i.e., subnetwork-broadcast or
subnetwork-multicast) packets delivered to a higher-layer protocol.
• In Octets (bytes) (Ethernet/Wireless-Slot A/B): The total number of octets received on the interface, including framing
characters.
• In Unicast Packets (Ethernet/Wireless-Slot A/B): The number of subnetwork unicast packets delivered to a
higher-layer protocol.
• Internal MAC Receive Errors (Ethernet): The number of frames for which reception fails due to an internal MAC
sublayer transmit error. A frame is only counted if it is not counted by the Frames Too Long, Alignment Error, or FCS
Error counters.
• Internal MAC Transmit Errors (Ethernet): The number of frames for which transmission fails due to an internal MAC
sublayer transmit error. A frame is only counted if it is not counted by Late Collision, Excession Collision, or Carrier
Sense Error counters.
• Last Change (Ethernet/Wireless-Slot A/B): The value of the sysUpTime object at the time the interface entered its
current operational state.
• Late Collisions (Ethernet): The number of times that a collision is detected on a particular interface later than 512
bit-times into the transmission of a packet
• MAC Address (Wireless-Slot A/B): The station's assigned, unique MAC address,
• Maximum Packet Size (Ethernet/Wireless-Slot A/B): The size (in octets) of the largest datagram which can be
sent/received
• MIB Specific Definition (Ethernet/Wireless-Slot A/B): A reference to MIB definitions specific to the particular media
being used to realize the interface. For example, if the interface is an Ethernet interface, then this field refers to a
document defining objects specific to ethernet.
• Multicast Received Frame Count (Wireless-Slot A/B): The number of multicast packets received.
• Multicast Transmitted Frame Count (Wireless-Slot A/B): The number of multicast packets transmitted.
• Multiple Collision Frames (Ethernet): The number of successfully transmitted frames for which transmission is
inhibited by more than one collision.
• Multiple Retry Count (Wireless-Slot A/B): The number of packets successfully transmitted after more than one
retransmission.
• Operational Status (Ethernet/Wireless-Slot A/B): The current state of the interface: Up (ready to pass packets),
Down (not ready to pass packets, or Testing (testing and unable to pass packets).
