show ports stats
show ports <port_list> statistics
Description
Displays real-time port statistics.
Syntax Description
Default
N/A.
Usage Guidelines
If you do not specify a port number or range of ports, statistics are displayed for all ports.
Jumbo frame statistics are displayed for switches only that are configured for jumbo frame support.
This status information may be useful for your technical support representative if you have a network
problem.
The switch collects the following port statistic information:
• Port Number
• Link Status—The current status of the link. Options are:
— Ready (R): The port is ready to accept a link.
— Active (A): 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.
