Configuration

Configuring the High Availability Feature for X.25 over LLC2

Step 1. To configure the standby device and the unique MAC address in the configuration file of the XOL primary interface, modify the following syntax:

 

 

Standby_device <standby LAN card name> # used for local

 

 

failover

 

 

XOL_floating_macaddr <unique MAC address>

 

 

 

NOTE

 

Local failover is automatically enabled by defining a standby_device in

 

 

the configuration file. If you do not require the local failover feature for

 

 

this interface, you must de-configure the standby_device by removing or

 

 

commenting the line in the configuration file. The standby XOL interface

 

 

inherits the configuration of the primary XOL interface during failover

 

 

because the same configuration file is used to configure the XOL

 

 

interface.

 

 

 

Example 3-5

 

Configuring Standby Device and Unique MAC Address

 

 

If the asumptions in the XOL configuration file are the following:

 

 

• The primary LAN card is lan0

 

 

• The standby LAN card is lan1

 

 

• The MAC address is 0x0060B0A4EbE5

 

 

Then, the XOL HA parameters take the following values:

standby_device

lan1

XOL_floating_macaddr 0x0060B0A4EBE5

NOTE

 

In the event of a failover, the XOL_floating_macaddr is moved from the

 

 

primary LAN card to the standby LAN card. HP recommends that you

 

 

use the primary and standby LAN cards only for the XOL links

 

 

configured with HA feature.

 

 

 

Step

2. To initialize the XOL HA interface with local failover support, run the

 

 

following command:
