FIGURE 23 Minimum required configuration for static NAT in Hot-Standby setup
1. On both ServerIron ADX units, place the untagged Hot-Standby port (sync-link) in a separate
VLAN and disable STP:
ServerIronADX(config)# vlan 99 by port
ServerIronADX(config-vlan-99)# untagged ethernet 1/12
ServerIronADX(config-vlan-99)# no spanning-tree
Placing the Hot Standby port in a separate VLAN prevents unnecessary traffic from going over
the sync-link. With Hot Standby, you cannot have spanning-tree configured anywhere on any
link connected between the two ServerIron ADX units.
2. Configure the server backup port, shared chassis-MAC address between the ServerIron ADX
units, and any connected router-ports:
ServerIronADX(config)# server backup ethernet 1/12 00e0.5201.0c72 vlan-id 99
ServerIronADX(config)# server router-ports ethernet 1/1
The server backup ethernet command must be configured exactly the same on both devices.
The <mac-addr> variable specifies the chassis-MAC address of one of the ServerIron ADX
units. Be sure to use a chassis MAC address from one of the two devices, not the MAC address
of one of the backup ports. Use show chassis to locate the chassis MAC address.
The server router-ports command enables the ServerIron ADX to count the number of
upstream (or downstream) router ports connected to the device.
