Viewing Port Errors - Extreme Networks ExtremeWare XOS Guide Manual

Status Monitoring and Statistics
Values are displayed to nine digits of accuracy.
To view port statistics, use the following command:
show ports {<port_list>} statistics {no-refresh}
The switch collects the following port statistical information:
Link Status—The current status of the link. Options are:
●
Active (A)—The link is present at this port.
■
Ready (R)—The port is ready to accept a link.
■
Not Present (NP)—The port is configured, but the module is not installed in the slot (modular
■
switches only).
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. Beginning with ExtremeWare XOS 11.3, the switch
automatically refreshes the display (this is the default behavior).
You can also display a snapshot of the port errors at the time you issue the command and view the
output in a page-by-page mode (this was the default behavior in ExtremeWare XOS 11.2 and earlier).
This setting is not saved; therefore, you must specify the
snapshot of the port errors.
To view port transmit errors, use the following command:
show ports {<port_list>} txerrors {no-refresh}
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:
●
Active (A)—The link is present at this port.
■
Ready (R)—The port is ready to accept a link.
■
Not Present (NP)—The port is configured, but the module is not installed in the slot (modular
■
switches only).
