tcps_rexmttimeo configuration

[loganathan nallusamy]

Hi folks

I have been trying to understand how many TCP control pkts have been transmitted through my testing with astf mode. In that perspective, is there a way for us to configure tcps_rexmttimeo (retransmit timeouts) dynamically based on the application need while running trex client & server ?

Any leads on this will be appreciated a lot.

Pls help us on this.

Thanks

Hi, 

The list of parameters that can be configured is found here: https://trex-tgn.cisco.com/trex/doc/trex_astf.html#_tunables_reference_a_id_tunables_a

You might want to look at 

tcp.rexmtthresh

Thanks. 

Indeed, i want to tune the timeout/duration by which client/server has to wait before initiating the next SYN  or any control pkt where as the rexmtthresh denotes the number of re-transmissions. dont i ?

tcp.rexmtthresh

1-10

number of duplicate ack to trigger retransimtion.
