Configuring XOL HA for Local Failover Without ServiceGuard

In Figure 3-13, system A has two LAN cards, namely, lan0 (the primary LAN card) and lan1 (the standby LAN card). The standby LAN card provides local failover for the XOL interface with X.121 address 1111. The user supplied, unique MAC address that is specified in the XOL configuration file as a value for the field XOL_floating_macaddr, for that LAN segment is uMAC.

The XOL interface with X.121 address 1111 is brought up on lan0 on system A (uMAC is automatically assigned to lan0 on system A when the XOL interface is initialized).

Figure 3-13 Before the Failover

When the lan0 (the primary LAN card) fails, the XOL interface stops on lan0, and a XOL interface is brought up automatically on lan1 (the standby LAN card on system A) using the same configuration file. An attempt is made to configure lan0 with the factory default MAC address, and uMAC is assigned to lan1 on system A during the local failover. The
