LLT provides various configuration and tunable parameters to modify and control the behavior of the LLT module. This section describes some of the LLT tunable parameters that can be changed at run-time and at LLT start-time.

See About Low Latency Transport (LLT).

The tunable parameters are classified into two categories:

LLT timer tunable parameters

See About LLT timer tunable parameters.
LLT flow control tunable parameters

See About LLT flow control tunable parameters.

You can set the LLT tunable parameters either with the lltconfig command or in the /etc/llttab file. You can use the lltconfig command to change a parameter on the local node at run time. Symantec recommends you run the command on all the nodes in the cluster to change the values of the parameters. To set an LLT parameter across system reboots, you must include the parameter definition in the /etc/llttab file. Default values of the parameters are taken if nothing is specified in /etc/llttab. The parameters values specified in the /etc/llttab file come into effect at LLT start-time only. Symantec recommends that you specify the same definition of the tunable parameters in the /etc/llttab file of each node.

To set a timer tunable:

To set a timer tunable parameter using the lltconfig command:
```
# lltconfig -T timer tunable:value
```
To set a timer tunable parameter in the /etc/llttab file:
```
set-timer  timer tunable:value
```

To set a flow control tunable

To set a flow control tunable parameter using the lltconfig command:
```
# lltconfig -F flowcontrol tunable:value
```
To set a flow control tunable parameter in the /etc/llttab file:
```
set-flow  flowcontrol tunable:value
```

See the lltconfig(1M) and llttab(1M) manual pages.
