Руководство Пользователя для Cisco Cisco Content Security Management Appliance M1070

If you want to perform system maintenance, place the Security Management appliance into the offline 
state. The s

uspend

 and o

ffline

 commands put AsyncOS into offline state. The offline state is 

characterized by the following:

Inbound email connections are not accepted.

Outbound email delivery is halted.

Log transfers are halted.

The CLI remains accessible.

You must enter a delay for the appliance to enter the offline state. The default delay is 30 seconds. 
AsyncOS allows open connections to complete during the delay, after which it forcefully closes open 
connections. If there are no open connections, the offline state commences immediately.

The difference between the suspend command and the offline command is that the suspend command 
retains its state even after the machine is rebooted. If you issue the suspend command and reboot the 
appliance, you must use the resume command to return the system to an online state.
