FS S3410 Series 24-Port Gigabit Ethernet L2+ PoE+ Switch
Fault Phenomenon
Port aggregation is unsuccessful.
Possible Cause of Failure
- Physical link failure.
- LACP negotiation was unsuccessful.
- There is no change in the packet flow and the matching part of the balance factor.
- The duplex, rate, and transmission medium at both ends are inconsistent.
Processing Steps
Check Whether There is a Link Failure On the Aggregation Member Port
FS#show interface status //Check whether the port status of the aggregation member port is up.
If the member port is down, check the physical port connection. Make sure the member is up. If conditions permit, replace other member ports, confirm whether the aggregation member port can be up, and exclude the member port from physical failure.
Check the Port Properties of Both Devices
Use the show interface XX command to view the port’s media properties, focusing on the port’s speed, flow control, and media type, and it needs to be configured in full-duplex mode to eliminate the problem that the port cannot be up

Check Whether the Link Aggregation Member Ports and Link Aggregation Groups Are Normal
State: Member port negotiation status, bndl indicates that the negotiation is successful, susp indicates that the negotiation fails, and down indicates that the link status of the interface is down

- switchport: AP Whether the interface is a Layer 2 port, Enabled indicates a Layer 2 port, and Disabled indicates not a Layer 2 port.
- Mode: AP The attributes of the Layer 2 interface of the interface, including ACCESS, TRUNK, TUNNEL, HYBRID, UPLINK, HOST, and PROMIS, when the AP interface is not a Layer 2 interface, the display is empty.
- Load balance: AP Balance mode of the interface

Check the Aggregation Port Configuration is Correct
- FS#show running-config interface TenGigabitEthernet 0/19
- Building configuration…
- Current configuration: 62 bytes
- interface TenGigabitEthernet 0/19
- port-group 1 mode active
There are two LACP port modes: Active and Passive
Check Whether the Configuration Of The Peer Device is Correct
If the LACP mode of both ports of the device is passive mode, the aggregation relationship cannot be established. Both ends are in active mode, or one side is in active mode and one is in passive mode.
