Description | This article describes how to analyze FortiLink communication using the CLI command. |
Scope | FortiGate. |
Solution |
FortiLink is a feature used in Fortinet’s security fabric to connect FortiSwitches to FortiGates. SSH into the FortiGate and run the following command:
diagnose debug console timestamp enable diagnose debug application fortilink <level> 1 to 4 (higher numbers provide more detailed output). diagnose debug enable diagnose debug disable <----- Execute the when finished.
Caution: Debugging can generate a large amount of output and may affect performance. Always advisable to run commands during maintenance windows.
Output:
2024-10-19 09:03:51 591s:749ms:448us flp_send_pkt[460]:pkt-sent {type(5) flag=0x1ac2 node(internal6) sw(internal6) len(26)smac: 4:d5:90:80:85:4c dmac:70:4c:a5:ab:3d:d0
Note: The above will display output <level> 1: (minimal output)
Upon analyzing the debug logs related to network activity, it is evident that a packet is being transmitted from the device. The number within the parentheses denotes a specific category of packet or protocol. These categories encompass different network protocols like data packets, control messages, or management traffic.
pkt-sent: This field indicates that the device is sending out packets.
