7 Using MLAG in Dell Networks

Change any settings mentioned below on both

the MLAG peers when required. Enable MLAG only after

the above settings are configured on the two peer switches.

It is also recommended for MLAG to be temporarily disabled in order to make subsequent changes to the

above settings.

Note: Be sure to schedule down time if making changes that impact traffic or cause data loss.

Note: Failure to make these areas identical may cause sporadic traffic issues on the network which are

difficult to troubleshoot.
