Chapter 3 CLI Commands
(config) accelerator mapi
(config) accelerator mapi
To enable the MAPI application accelerator, use the accelerator mapi global configuration command.
To disable the MAPI application accelerator, or one of its options, use the no form of this command.
accelerator mapi {enable | read-opt | write-opt | reserved-pool-size maximum-percent
max_percent | exception {coredump | debug | no-coredump}}
no accelerator mapi {enable | read-opt | write-opt | reserved-pool-size maximum-percent
max_percent | exception {coredump | debug | no-coredump}}
Syntax Description
Defaults The MAPI accelerator is enabled by default and will start automatically if the Enterprise license is
installed. The read optimization (read-opt) and write optimization (write-opt) features are enabled by
default when the MAPI accelerator is enabled. The default maximum reserved connection pool percent
is 15. The default exception action is coredump.
Command Modes global configuration
Device Modes application-accelerator
Usage Guidelines Use the accelerator mapi enable command to enable MAPI acceleration. This feature supports
Microsoft Outlook 2000–2007 clients. Secure connections that use message authentication (signing) or
encryption are not accelerated and MAPI over HTTP is not accelerated.
You must enable the EPM accelerator before the MAPI accelerator can operate.
Use the reserved-pool-size keyword to restrict the maximum number of connections reserved for MAPI
optimization during TFO overload. It is specified as a percent of the TFO connection limit of the
platform. Valid percent ranges from 5%-50%. The default is 15% which would reserve approximately
0.5 connection for each client-server Association Group (AG) optimized by MAPI accelerator.
enable Enables the MAPI traffic accelerator.
read-opt Enables the read-ahead optimization of the MAPI traffic for mail reading.
write-opt Enables the asynchronous write optimization of the MAPI traffic for mail
sending.
reserved-pool-size
maximum-percent
max_percent
Configures the maximum reserved connection pool percent, specified as the
percent of the device TFO connection limit, to restrict the maximum
connections reserved for MAPI optimization during TFO overload. Range is
from 5 to 50. Default is 15.
exception (Optional) Configures the action to be taken if an exception occurs.
coredump Writes a core file (default).
debug Hangs the system until it is explicitly restarted.
no-coredump Restarts the accelerator and does not write a core file.
