LACP out of sync errors
We have a redundant pair of 3400 LTMs, and have LACP port trunks working to a stack of Cisco 3750G switches, and to our Cisco 6509 core. However we seem to have trouble getting the LACP to function probably with a new Cisco 3750E switch stack. All settings appear the same, but the F5 and Cisco 3750E switches are complaining about out of sync errors.
