Commands for Status Monitoring and Statistics
• Receive Jabber Frames (RX Jabber)—The total number of frames received by the port that was of
greater than the support maximum length and had a Cyclic Redundancy Check (CRC) error.
• Receive Alignment Errors (RX Align)—The total number of frames received by the port that occurs if
a frame has a CRC error and does not contain an integral number of octets.
• Receive Frames Lost (RX Lost)—The total number of frames received by the port that were lost
because of buffer overflow in the switch.
For version 2.0 and 4.0
• Disabled and Not Present are not available as link status indicators.
Examples
The following command displays receive error statistics for ports 1 through 3 on a stand-alone switch:
show ports 1-3 rxerrors
The following command displays receive error statistics for slot 1, ports 1 through 3 on a modular
switch:
show ports 1:1-1:3 rxerrors
The following command displays receive error statistics for slot 1, ports 1 through 3 on a modular
