Step 3
In the Reserved Pool Size Maximum Percent field, enter the maximum percent of connections 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 the MAPI accelerator.
The client maintains at least one AG per server it connects to with an average of about 3 connections per
AG. For deployments that observe a greater average number of connections per AG, or where TFO
overload is a frequent occurrence, a higher value for reserved pool size maximum percent is
recommended.
Reserved connections would remain unused when the device is not under TFO overload. Reserved
connections are released when the AG terminates.
Step 4 Click Submit. The changes are saved to the device or device group.
Configuring Encrypted MAPI Acceleration
The Encrypted MAPI acceleration feature provides WAN optimization for secure MAPI application
protocols using MS-Kerberos security protocol and Windows Active Directory identity for
authentication of clients and/or servers in the domain.
Note The Encrypted MAPI feature is in extended beta trials. You must contact
[e-mail] with your Cisco account team on the cc: for approvals before
enabling this feature. Only approved customers will be supported for beta evaluations.
