| Description | This article describes how to view the real-time transmit (Tx) rate and receive (Rx) traffic rates (bandwidth usage) for a specific port or all ports, and view port settings. |
| Scope | FortiSwitch. |
| Solution |
To check the port speed on a FortiSwitch, the following method is used:
Using the CLI: Access the FortiSwitch CLI via SSH or console. Enter the following command to display the real-time packet transmit information:
diagnose switch physical-ports linerate <port-number> <---- This will show the transmit (TX) and receive (RX) packet and rate information for the specified port.
diagnose switch physical-ports linerate <---- This will show the transmit (TX) and receive (RX) packet and rate information for each port.
diagnose switch physical-ports linerate up <---- This will show the transmit (TX) and receive (RX) packet and rate information only for active ports.
Output of the commands above:
FSW-CORE # diagnose switch physical-ports linerate port5
FSW-CORE # diagnose switch physical-ports linerate up
Alternatively, the following set of commands can be used:
config switch physical-port
The command above will display detailed information about the specified port, including its speed setting, as shown below. FGT-CORE# config switch physical-port FGT-CORE (physical-port) # edit port5 FGT-CORE (port5) # show full-configuration |
