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.
