hi,
Post both bridgeaggregation configurations, the 4 interface configurations (and the switch they belong to), and the software versions of the swtiches.
E.g.
switch (with bagg 10): display current-configuration interface Bridge-Aggregation 10 display current-configuration interface <interface in BAGG10> display current-configuration interface <other interface in BAGG10> display version switch (the otherswitch): display current-configuration interface Bridge-Aggregation <BAGG-otherswitch> display current-configuration interface <interface in BAGG-otherswitch> display current-configuration interface <other interface in BAGG-otherswitch> display version
Also, how is the link aggregation not working? What does the log say when you "up the links"?
Regards
