Active-standby TCS
TCS is supported in an active-standby configuration. Figure 27 illustrates a sample active-standby
TCS configuration. In this configuration, one of the ServerIron ADXs serves as the active ServerIron
ADX, while the other remains in standby mode. If the active ServerIron ADX fails, the standby
ServerIron ADX assumes the duties of the failed ServerIron ADX and becomes the new active
ServerIron ADX.

Configuring router R1
The following commands configure router R1 in Figure 27.
NOTE
This example shows commands that are valid on the ServerIron ADX device only when it is running
the Layer 3 router image.
ServerIronADX(config)# vlan 1 name DEFAULT-VLAN by port
ServerIronADX(config-vlan-1)# router-interface ve 1
ServerIronADX(config-vlan-1)# exit
ServerIronADX(config)# vlan 200 by port
ServerIronADX(config-vlan-1)# untagged ethe 9 to 16 ethe 26
ServerIronADX(config-vlan-1)# router-interface ve 2
ServerIronADX(config-vlan-1)# exit
ServerIronADX(config)# vlan 3 by port
ServerIronADX(config-vlan-1)# untagged ethe 17 to 18
ServerIronADX(config-vlan-1)# router-interface ve 3
ServerIronADX(config-vlan-1)# exit
