Specifying the Nagle Algorithm for SSL TCP Connections

OL-5655-01
To disable the timeout, set the value to 0:
(config-ssl-proxy-list[ssl_list1])# backend-server 1 tcp server
inactivity-timeout 0
To reset the timeout to the default value of 240 seconds, enter:
(config-ssl-proxy-list[ssl_list1])# no backend-server 1 tcp server
inactivity-timeout
The TCP Nagle algorithm automatically concatenates a number of small buffer
messages transmitted over the TCP connection between a client and the SSL
module or between a back-end server and the SSL module. This process increases
the throughput of your CSS by decreasing the number of packets sent over each
TCP connection. However, the interaction between the Nagle algorithm and the
TCP delay acknowledgment may increase latency in your TCP connection.
Disable the Nagle algorithm when you observe an unacceptable delay in a TCP
connection (clear-text or SSL).
Use the backend-server number tcp virtual nagle command to disable or
reenable the Nagle algorithm for the TCP connection between the client and the
SSL module. The syntax for this command is:
backend-server number tcp virtual nagle enable|disable
To disable the Nagle algorithm for the TCP connection between the client and the
SSL module, enter:
(config-ssl-proxy-list[ssl_list1])# backend-server 1 tcp virtual nagle
disable
To reenable the Nagle algorithm for the TCP connection between the client and
the SSL module, enter:
(config-ssl-proxy-list[ssl_list1])# backend-server 1 tcp virtual nagle enable
Use the backend-server number tcp server nagle command to disable or
reeanble the Nagle algorithm for the TCP connection between the server and the
SSL module. The syntax for this command is:
backend-server number tcp server nagle enable|disable
