• Default: stack
• Format: stack-port <unit/slot/port> [{ethernet | stack}]
• Mode: Stack Global Config

show stack-port

This command displays summary stack-port information for all interfaces.

• Format: show stack-port
• Mode: Privileged EXEC

For Each Interface:

• Unit: The unit number.
• Interface: The slot and port numbers.
• Configured Stack Mode: Stack or Ethernet.
• Running Stack Mode: Stack or Ethernet.
• Link Status: Status of the link.
• Link Speed: Speed (Gbps) of the stack port link.

show stack-port counters

This command displays summary data counter information for all interfaces.

• Format: show stack-port counters
• Mode: Privileged EXEC
• Unit: The unit number.
• Interface: The slot and port numbers.
• Tx Data Rate: Trashing data rate in megabits per second on the stacking port.
• Tx Error Rate: Platform-specific number of transmit errors per second.
• Tx Total Errors: Platform-specific number of total transmit errors since power-up.
• Rx Data Rate: Receive data rate in megabits per second on the stacking port.
• Rx Error Rate: Platform-specific number of receive errors per second.
• Rx Total Errors: Platform-specific number of total receive errors since power-up.

show stack-port diag

This command shows stack port diagnostics for each port and is only intended for Field Application Engineers (FAEs) and developers. An FAE will advise on the necessity to run this command and capture this information.

• Format: show stack-port diag
• Mode: Privileged EXEC
• Unit: The unit number.
• Interface: The slot and port numbers.
• Diagnostic Entry1: 80 character string used for diagnostics.
