Hi,   Please, refer to emc247936.  " The Dell switch sends 128 byte LACP packets, with four extra bytes at the end. The Data Mover appears to have a check for the length of the packet and it fails if it does not match, regardless of its contents."  There are patches for 5.6.49 that contains an enhancement to support this switch.  Gustavo Barreto.
Hi,  I have a NS-480 here that I am trying to get LACP working on with a stacked pair of Dell PowerConnect 6248 switches.  I currently have two other LACP links on the Dell switches (for uplink and for another server on the switches). Using the same configuration on the PowerConnects as the other links for the NS-480 links (only using cge0/1 on both data movers) results in the LACP link not coming up at all with the following errors reported in the logs (from the Celerra):  Facility: DRIVERS Description: LAP_Port::receive_LACP len=114 expected_len=110  This message is repeated over and over again, which I assume is why LACP is not working.  Has anyone got LACP working between EMC gear and a PowerConnect switch before? For troubleshooting purposes I also tried setting LACP up on a single switch (non stacked) incase that was causing any issues with no luck.  I had a look at the logs from the Dell switch but there doesn't appear to be anything meaningful in them.  Thanks
