I am trying to get a 4 x 1GbE LAG group connected between a server with Broadcom 5709C GigE interfaces, and four 1GbE ports on a blade on my Cat4506-E.
The server NICs are running the most current versions of the Broadcom Advanced Control Suite (BASC) and the most current versions of the Broaddcom drivers. Additionally, the Cat4506-E is running the most current platform supported version
The BASC utility offers the option of setting up an the LACP group as either "Link Aggregation" or as "Generic Trunking (FEC/GEC)/802.3ad-Draft Static".
Given that these are the two LACP options available for configuring the Broadcom driver for LACP, should the channel-group mode for the GigE ports on the 4506-E be configured for 'mode active' or 'mode on'?
And are there any best practice examples for how to best configure the LACP channel between these particular OEM NICs and the 4506-E?
