16.5.1.3 Binding MAC Address Binding Troubleshooting
Enabling MAC address binding for ports may fail in some occasions. Here are some possible causes and
solutions:
 If MAC address binding cannot be enabled for a port, make sure the port is not enabling port
aggregation and is not configured as a Trunk port. MAC address binding is exclusive to such
configurations. If MAC address binding is to be enabled, the functions mentioned above must be
disabled first.
 If a secure address is set as static address and deleted, that secure address will be unusable even
though it exists. For this reason, it is recommended to avoid static address for ports enabling MAC
address.
