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 “i” series 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 following port statistic information is collected by the switch:
• 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.
— Disabled (D): The link is disabled at this port.
— Not Present (NP): The link is not 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.
mgmt Specifies the management port. Supported only for switches that provide a
management port.
portlist Specifies one or more ports or slots and ports. On a modular switch, can be a
list of slots and ports. On a stand-alone switch, can be one or more port
