Syntax: configure sync-terminal

This command allows you to enter the configure sync-terminal level. Once at that level, you can

configure the features in the following categories:

• Layer 4 Server Load Balancing features, for example, SLB, Symmetric SLB, hot standby

redundancy

• Layer 7 Switching features such as URL switching, cookie switching, HTTP header hashing, and

SSL session ID switching

• Health checks

Enter a “?” at the CLI command line to display the list of commands allowed for synchronization.

Commands entered on ServerIron ADX A while at the configure sync-terminal level are duplicated

on ServerIron ADX B. The commands continue to be duplicated on ServerIron ADX B until you exit

out of the configure sync-terminal level.

If you enter an invalid command while you are at the configure sync-terminal level or if the

command you entered cannot be accepted by the destination ServerIron ADX, a message appears.

Example

Peer message: real server 1 not found

Also, some commands, such as no server real, may take a few seconds to process before the CLI is

available for the next command.

To see if the configuration entered at the configure sync-terminal level was successfully duplicated

on the destination ServerIron ADX, enter the show run command on the destination ServerIron

ADX. The duplicated configuration should be displayed.

Creating config-sync peers

To be able to send commands to other ServerIron ADXs, do the following before entering the

configure sync-terminal level:

• Ensure the physical ports used to connect the ServerIron ADXs are enabled.

• Enter the config-sync sender command on the source ServerIron ADX (the ServerIron ADX

where the commands will be entered), and enter the config-sync receiver command on the

destination ServerIron ADX (the ServerIron ADX where the commands will be received).

The config-sync sender command indicates the port on the source ServerIron ADX on which the

commands will be sent. The command also indicates the destination MAC address or VLAN ID on

the destination ServerIron ADX.
