Chapter 4 Configuring TCP/IP Normalization and IP Reassembly Parameters
•

•
The syntax of this command is as follows:
The number argument is the round-trip time (RTT) in milliseconds and controls
how the ACE applies TCP optimizations as follows:
•
•
•
For example, to specify the ACE applies TCP optimizations to packets for the life
of a connection, enter:
host1/C1(config-parammap-conn)# set tcp wan-optimization rtt 0
To restore the ACE behavior to the default of not optimizing TCP connections,
enter:
host1/C1(config-parammap-conn)# no set tcp wan-optimization rtt 0

Acknowledgement (ACK) delay timer (see the
Timer" section)
Window-scale factor (see the
Retry settings (see the
section)
set tcp wan-optimization rtt number
For a value of 0, the ACE applies TCP optimizations to packets for the life of
a connection.
For a value of 65535 (the default), the ACE performs normal operations (no
optimizations) for the life of a connection.
For values from 1 to 65534, the ACE applies TCP optimizations to packets
based on the client RTT to the ACE as follows:
If the actual client RTT is less than the configured RTT, the ACE
–
performs normal operations for the life of the connection.
If the actual client RTT is greater than or equal to the configured RTT,
–
the ACE performs TCP optimizations on the packets for the life of a
connection.
