2.5 Ethernet Link Aggregation Troubleshooting

Fault: You might see the prompt of configuration failure when configuring link
aggregation.
Troubleshooting:
I. For S3526/S3526 FM/S3526 FS Ethernet Switches, take the following steps
Check the input parameter and see whether the starting number of Ethernet port is
smaller than the end number. If yes, take the next step.
Check the input parameter and see whether the first number is correct. If yes, take
the next step.
Check whether the Ethernet ports that are in the configured range belong to any
other existing link aggregations. If not, take the next step.
Check whether the ports to be aggregated operate in the same speed and full
duplex mode. If yes, take the next step.
Check if there are no more than eight ports in one group.
