Traffic
Packets

RX PKTS: Displays the number of good packets received.

TX PKTS: Displays the number of good packets transmitted.

Bytes

RX Bytes: Displays the number of octets (bytes) with no errors received by the interface.

TX Bytes: Displays the number of octets (bytes) with no errors sent by the interface.

Port
Mode The Mode can be either of the following:
  • Access: This Ethernet interface accepts packets only from the native VLANs.
  • Trunk: This Ethernet interface allows packets from a list of VLANs you can add to the trunk.
Tagged

Indicates whether the VLAN is tagged, as follows:

  • : means the native VLAN is tagged.
  • : means the native VLAN is untagged.
VLAN Displays the tag assigned to the native VLAN (if mode is Trunk) or the access VLAN (if mode is Access).
FA VLAN Displays the tag assigned to the Fabric Attach (FA) client VLAN (if mode is Access).
Allowed VLANs Displays the VLANs that exclusively send packets over the port (if mode is Trunk).
IP
IPv4 Displays the IP address of the interface.
Primary The presence of a check mark indicates that the IP address is assigned to this interface either through DHCP or through static IP assignment.
Default Gateway Displays the Default Gateway's IP address. This is the gateway used to route traffic to the specified network.
Name Server Displays the names of the servers designated to provide DNS resources to this access point.
RX Packets Displays the number of multicast/unicast/broadcast packets received through the selected GbE interface in a pie chart.
TX Packets Displays the number of multicast/unicast/broadcast packets sent through the selected GbE interface in a pie chart
Errors
RX Displays RX Errors in a pie chart, as follows:
  • FIFO Errors: Displays the number of FIFO errors received at the interface. First-In First-Out queueing is an algorithm that involves buffering and forwarding of packets in the order of arrival. FIFO entails no priority for traffic. There is only one queue, and all packets are treated equally.
  • Frame Errors: Displays the number of frame errors received at the interface. A frame error occurs when a byte of data is received, but not in the format expected.
  • Length Errors: Displays the number of length errors received at the interface. Length errors are generated when the received frame length was less than (or exceeded) the Ethernet standard.
  • Missed Errors: Displays the number of missed packets. Packets are missed when the hardware received FIFO has insufficient space to store the incoming packet.
  • Oversize Errors: Displays the number of overflow errors. An overflow occurs when packet size exceeds the allocated buffer size.
TX Displays TX Errors in a pie chart, as follows:
  • Error: Displays the number of packets with errors transmitted on the interface.
  • FIFO: Displays the number of FIFO errors received at the interface. Firstin-First-Out queueing is an algorithm that involves the buffering and forwarding of packets in the order of arrival. FIFO entails no priority for traffic. There is only one queue, and all packets are treated equally.
  • Aborted: Displays the number of packets aborted on the interface because a clear-to-send request was not detected.
  • Carrier: Displays the number of carrier errors on the interface. This generally indicates bad Ethernet hardware or cabling.
  • Heart Beat: Displays the number of heartbeat errors. This generally indicates a software crash or packets stuck in an endless loop.
  • Window Errors: Displays the number of window errors transmitted. TCP uses a sliding window flow control protocol. In each TCP segment, the receiver specifies the amount of additional received data (in bytes) in the receive window field the receiver is willing to buffer for the connection. The sending host can send only up to that amount. If the sending host transmits more data before receiving an acknowledgment from the receiving host, it constitutes a window error.
Bad Pkts Received Displays the number of bad packets received through the interface.
MAC TX Errors Displays the number of transmits that failed because of an internal MAC sublayer error that is not a late collision, excessive collision count, or a carrier sense error.
MAC RX Errors Displays the number of received packets failed because of an internal MAC sublayer that is not a late collision, excessive collision count, or a carrier sense error.
Collisions Displays the number of collisions on the interface.
Excessive Collisions Displays the number of excessive collisions. Excessive collisions occur when the traffic load increases to the point that a single Ethernet network cannot handle it efficiently.
Late Collisions A late collision is any collision that occurs after the first 64 octets of data have been sent by the sending client. Late collisions are not normal, and are usually the result of out-of-specification cabling or a malfunctioning device.
Drop Events Displays the number of dropped packets transmitted or received through the interface.
TX Undersize Pkts Displays the number of undersized packets transmitted through the interface.
Oversize Pkts Displays the number of oversized packets transmitted through the interface.
Bad CRC Displays the CRC error. The Cyclical Redundancy Check (CRC) is the 4-byte field at the end of every frame. The receiving station uses it to interpret whether the frame is valid. If the CRC value computed by the interface does not match the value at the end of the frame, it is considered a bad CRC.
