Blocking Notes and Caveats

The following notes and caveats apply to blocking:
The ARC is formerly known as Network Access Controller. Although the name has been changed,
the IDM, the IME, and the CLI contain references to Network Access Controller, nac, and
network-access.
Blocking is not supported on the FWSM in multiple mode admin context.
Connection blocks and network blocks are not supported on adaptive security appliances. Adaptive
security appliances only support host blocks with additional connection information.
