Status Monitoring and Statistics
ExtremeWare XOS 11.1 Concepts Guide
122
The switch collects the following port statistical information:
●
Link Status—The current status of the link. Options are:
■
Ready (the port is ready to accept a link).
■
Active (the link is present at this port).
●
Transmitted Packet Count (Tx Pkt Count)—The number of packets that have been successfully
transmitted by the port.
●
Transmitted Byte Count (Tx Byte Count)—The total number of data bytes successfully transmitted
by the port.
●
Received Packet Count (Rx Pkt Count)—The total number of good packets that have been received
by the port.
●
Received Byte Count (RX Byte Count)—The total number of bytes that were received by the port,
including bad or lost frames. This number includes bytes contained in the Frame Check Sequence
(FCS), but excludes bytes in the preamble.
●
Received Broadcast (RX Bcast)—The total number of frames received by the port that are addressed
to a broadcast address.
●
Received Multicast (RX Mcast)—The total number of frames received by the port that are addressed
to a multicast address.
Viewing Port Errors
The switch keeps track of errors for each port.
To view port transmit errors, use the following command:
show ports {<port_list>} txerrors
The switch collects the following port transmit error information:
●
Port Number—The number of the port
●
Link Status—The current status of the link. Options are:
■
Ready (the port is ready to accept a link).
■
Active (the link is present at this port).
●
Transmit Collisions (TX Coll)—The total number of collisions seen by the port, regardless of whether
a device connected to the port participated in any of the collisions.
●
Transmit Late Collisions (TX Late Coll)—The total number of collisions that have occurred after the
port’s transmit window has expired.
●
Transmit Deferred Frames (TX Deferred)—The total number of frames that were transmitted by the
port after the first transmission attempt was deferred by other network traffic.
●
Transmit Errored Frames (TX Error)—The total number of frames that were not completely
transmitted by the port because of network errors (such as late collisions or excessive collisions).
●
Transmit Parity Frames (TX Parity)—The bit summation has a parity mismatch.
To view port receive errors, use the following command:
show ports {<port_list>} rxerrors
