failover connection
Sets failover connection settings.
Syntax
[no] failover connection {attempts <attempts> | failed <timeout> | timeout <timeout>}
Parameters
attempts <attempts> | Sets the number of times the backup SteelHead attempts to reconnect to the master SteelHead after a read time-out has expired. The default value is 5 attempts. |
failed <timeout> | Sets the connection failed timeout setting. |
timeout <timeout> | Sets the number of milliseconds the SteelHead waits before aborting the reconnection attempt to the master SteelHead. The default value is 2000 ms. |
Usage
You can adjust the timers for faster master appliance and backup appliance failover. 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 the failover connection command to adjust the number of times the backup SteelHead attempts to reconnect to the master SteelHead after a read time-out has expired. You can adjust the read time-out value by using the failover read timeout command.
The no command option resets the failover connection settings to the default values.
Example
amnesiac (config) # failover connection timeout 1000
