Process exceptions can sometimes occur with the L2SYSD process when combinations of ACL limits
are approached or exceeded.
Constant MAC learning and flushing can occur when ASIC table limitations are exceeded. Layer 2
frame switching can fail if the number of MAC address table entries is exceeded.

AMPP is not working
Configuring Brocade Automatic Migration of Port Profiles (AMPP) is complex. It works in standalone
mode and VCS Fabric mode. For details on configuring AMPP, refer to
Problems encountered while using AMPP are usually the result of configuration errors in the port-profile
itself, errors in the associated virtual machine (VM) configuration, or compatibility problems between the
host adapters and AMPP. Specifically, AMPP problems can be caused by the following conditions:
• A port-profile configuration does not exist on the target switch or does not contain a basic switchport
and VLAN configuration. Refer to
Verifying the port-profile configuration
on page 678.
• The VM MAC address does not appear in the MAC address table. Refer to
on page 678.
