Proxim AP-4000 User Manual

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 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 Recieve 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 Collission, 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).
