To troubleshoot port aggregation issues on the FS S3410 Series 24-Port Gigabit Ethernet L2+ PoE+ Switch, you can follow these steps:
1. Check for any physical link failures on the aggregation member ports. Use the command "FS#show interface status" to check the port status of the aggregation member ports. If any member port is down, check the physical port connection and ensure it is up. If possible, try replacing other member ports to confirm if the aggregation member port can be brought up, ruling out any physical failures.
2. Verify the port properties of both devices. Use the command "show interface XX" (replace XX with the specific interface number) to view the port's media properties such as speed, flow control, and media type. Ensure that the port is configured in full-duplex mode to eliminate any issues with the port not coming up.
3. Check the status of the link aggregation member ports and link aggregation groups. Use the command "FS#show lacp summary" to check the negotiation status of the member ports. Look for the "bndl" (bundle) status, which indicates successful negotiation, "susp" (suspended) status, which indicates failed negotiation, or "down" status, which indicates that the link status of the interface is down.
4. Verify the configuration of the aggregation port. Use the command "FS#show aggregatePort 1 summary" to check the configuration of the aggregation port. Ensure that the mode is correctly set and that the load balancing is configured properly.
5. Check the configuration of the peer device. Verify that the LACP mode of both ports on the peer device is either active mode or passive mode. If both ends are in passive mode, the aggregation relationship cannot be established. Both ends should be in active mode or one side in active mode and the other in passive mode.
If the above steps do not resolve the issue, you can seek technical support from FS by collecting the following information and contacting their technical support team:
- "show run" command output
- "show version" command output
- "show version slot" command output
- "show lacp summary X" command output (replace X with the specific aggregation group number)
- "show logging" command output
