High availability configurations

In Figure 3, the commands you enter on ServerIron ADX A while that device is at the configure

sync-terminal level, are duplicated on ServerIron ADX B.

Preparing for synchronization

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

configure sync-terminal level:

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

• Make sure that you have enabled the config-sync mac command on the source ServerIron ADX

(the ServerIron ADX where the commands will be entered). Do not enter the config-sync mac

command on the destination ServerIron ADXs (the ServerIron ADXs where the configuration

will be duplicated).

NOTE

If you configure config-sync mac on both ServerIron ADXs, this feature will not work.

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

be sent. It also indicates the destination MAC address or VLAN ID on the destination ServerIron

ADX. For example, if you are configuring hot standby on ServerIron ADX A and those commands will

be duplicated on ServerIron ADX B, begin the synchronization by entering commands such as the

following on ServerIron ADX A.

ServerIronADXA# configure terminal

ServerIronADXA(config)# config-sync eth 2/1 mac 00e0.5201.0c72

ServerIronADXA(config)# write mem

ServerIronADXA(config)# exit

ServerIronADXA#

Syntax: config-sync ethernet <port-number> mac <mac-address> [vlan <vlan-ID>]

The ethernet <port-number> parameter indicates which port on the source ServerIron ADX will be

used to send the commands.

The mac <mac-address> parameter indicates the destination port of the commands on the

destination ServerIron ADX.

The vlan <vlan-ID> parameter indicates the destination VLAN of the commands on the destination

ServerIron ADX.

Initiating and ending the synchronization

Once you have indicated the port on which the commands will be sent and the destination MAC

address or VLAN ID, you can begin to synchronize the configuration by entering commands such as

the following on the source ServerIron ADX.

Port1/1

ServerIron A

IP: 192.168.1.1

Port2/1

ServerIron B

IP: 192.168.1.2

MAC address: 00e0.5201.0c72
