then re-enabling it using the no shutdown command.

Disabling MAC Address Learning on the System

You can configure the system to not learn MAC addresses from LACP and LLDP BPDUs.
To disable source MAC address learning from LACP and LLDP BPDUs, follow this procedure:
• Disable source MAC address learning from LACP BPDUs.
CONFIGURATION mode
mac-address-table disable-learning lacp
• Disable source MAC address learning from LLDP BPDUs.
CONFIGURATION mode
mac-address-table disable-learning lldp
• Disable source MAC address learning from LACP and LLDP BPDUs.
CONFIGURATION mode
mac-address-table disable-learning
If you don't use any option, the mac-address-table disable-learning command disables source
MAC address learning from both LACP and LLDP BPDUs.
