failover read timeout
Specifies the failover read settings.
Syntax
[no] failover read timeout <timeout>
Parameters
<timeout> | Failover read time-out value, in milliseconds. The default value is 5000. |
Usage
You can adjust the timers for faster master and backup failover for SteelHeads. In a steady, normal operating state, the backup SteelHead periodically sends keep-alive messages to the master SteelHead on TCP port 7820. If the master SteelHead does not respond to the keep-alive message within five seconds, the backup SteelHead drops the connection and attempts to reconnect to the master SteelHead. The backup SteelHead attempts to reconnect a maximum of five times, and each time it waits for two seconds before aborting the connection.
If all connection attempts fail, the backup SteelHead transitions into an active state and starts optimizing the connections. If you use the default value failover settings, it can take as long as 15 seconds before the backup SteelHead starts optimizing connections.
Use this command to adjust the amount of time, in milliseconds, that the backup SteelHead waits for the master SteelHead to respond to its keep-alive messages.
The no command option resets the failover read settings to the default value.

amnesiac (config) # failover read timeout 1000
