A blacklist log records the following information:

·     Remote IP address of the DS-Lite tunnel.

·     VPN instance (VRF) name.

·     Reason for adding or deleting the blacklist entry.

Restrictions and guidelines

·     Only one log operation (import, export, or delete) is allowed at a time.

·     Only one user can perform a log operation at a time. When you import, export, or delete logs, make sure no one else is performing a log operation.
