tcp-options
Hello,
We're migrating our current LB from ACEs to A10.
One particular Sfarm on ACE has the following option:
parameter-map type connection TCP_IDLE_30
set timeout inactivity 1800
set tcp timeout half-closed 600
tcp-options selective-ack allow
From Cisco:
selective-ack - Allows the ACE to inform the sender about all segments that it received. The sender needs to retransmit the lost segments only, rather than wait for a cumulative acknowledgement or retransmit segments unnecessarily. Selective ACK (SACK) can reduce the number of retransmitted segments and increase the throughput under some circumstances.
Q: How to apply a similiar config on A10 of the tcp-options selective-ack allow ?
Is it possible ? already enabled ?
Thank you

The Selective ACK(SACK) within the TCP Option is enabled by default in 2.7 and 4.x code. There is no option to turn off/on hence, code conversation for "tcp-options selective-ack allow" is not required. Good Luck!
