Message CodeASA-4-412002
SeverityWarning
DescriptionDetected bridge table full while inserting MAC MAC_address on interface interface. Number of entries = num
ExplanationThis message is generated when the bridge table is full and an attempt is made to add one more entry. The adaptive security appliance maintains a separate Layer 2 forwarding table per context and the message is generated whenever a context exceeds its size limit. The MAC address will be added, but it will replace the oldest existing dynamic entry (if available) in the table.
User ActionThis might be an attempted attack. Make sure that the new bridge table entries are valid. In case of attack, use EtherType ACLs to control access to vulnerable hosts.
