IP TCP SYNACK RETRIES

ip tcp synack-retries

Overview Use this command to specify how many times the switch will retry sending a SYN
ACK for a TCP connection for which it has received a SYN but not an ACK. Such
connections are called half-open TCP connections. This command allows you to
influence how long half-open TCP connections take to time out.
Use the no variant of this command to return to the default setting of 5 retries.
ip tcp synack-retries <0-255>
Syntax
no ip tcp synack-retries
Default 5 retries
Mode Global Configuration
Usage notes The following table shows the approximate correlation between the number of
retries and the time half-open TCP connections take to time out.
Example To retry twice, which leads to a timeout of approximately 7 seconds, use the
commands:
awplus#
awplus(config)#
