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
z 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.
z Check the input parameter and see whether the first number is correct. If yes, take
the next step.
z Check whether the Ethernet ports that are in the configured range belong to any
other existing link aggregations. If not, take the next step.
z Check whether the ports to be aggregated operate in the same speed and full
duplex mode. If yes, take the next step.
z Check if there are no more than eight ports in one group.
