Field Description
Unit Indicates where the port resides:
• Base (for example, 1783-MS10T).
• Expansion module (for example, 1783-MX08T).
Port Indicates the port selected for configuration.
The port number includes the port type (Fa for Fast Ethernet and Gi for Gigabit Ethernet), the base or expansion module
number (1, 2, or 3), and the specific port number, such as in the following examples:
• Gi1/1 is Gigabit Ethernet port 1 on the base.
• Fa2/1 is Fast Ethernet port 1 on the first expansion module.
Interface Counters Let you view the status of octets received and sent and packets received and sent:
• Octets In—The number of octets received by the port.
• Octets Out—The number of octets sent by the port.
• Ucast Packets In —The number of unicast packets received by the port.
• Ucast Packets Out —The number of unicast packets sent by the port.
• NUcast packets In—The number of multicast packets received by the port.
• NUcast packets Out—The number of multicast packets sent by the port.
• Discards In—The number of inbound packets that have been discarded.
• Discards Out—The number of outbound packets that have been discarded.
• Errors In—The number of inbound packets that contain errors.
• Errors Out—The number of outbound packets that contain errors.
• Unknown Protos (Protocols) In—The number of inbound packets with unknown protocols.
Media Counters Let you view the number of collisions on a link.
Collision counters:
• Single —The number of single collisions.
• Multiple —The number of multiple collisions.
• Late —The number of late collisions.
• Excessive—The number of frames for which transmission fails due to excessive collisions.
Error counters:
• Alignment—The number of frames received that are not an integral number of octets in length.
• FCS (Frame Check Sequence)—The number of frames received that do not pass the FCS check.
• SQE Test Errors—The number of times that the SQE TEST ERROR message is generated.
• Deferred Transmissions—Count of transmissions deferred by busy network.
• MAC Xmit Errors—The number of frames that failed to transmit due to an internal MAC sublayer transmit error.
• MAC Recv Errors—The number of frames that failed to be received due to an internal MAC sublayer receive error.
• Carrier Sense—The number of times the carrier sense condition was lost or never asserted when attempting to
transmit a frame.
• Frame Too Long—The number of frames received that exceed the maximum permitted frame size.
