I got this error mesage in the log:
"%EC-SPSTBY-5-CANNOT_BUNDLE_LACP: Te5/5 is not compatible with aggregators in channel 4 and cannot attach to them (qos-card types of Te5/5 do not match Te6/5)"
According to Cisco error message decoder:
"%EC-5-CANNOT_BUNDLE_LACP: [char] is not compatible with aggregators in channel [dec] and cannot attach to them ([char])
This port has different port attributes than other ports within the port channel.
Recommended Action: Match the port attributes to that of the port channel."
Ive checked my configurations and the interface configurations are identical.
