Configuration

Configuring the High Availability Feature for X.25 over LLC2

Chapter 3 85

Step 1. T

o configure the standby device and the unique MAC address in the

nfiguration 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

llowing command:

1 2 ... 80 81 82 83 84 85 86 87 88 89 90 ... 260 261
