Establishing the LAN adapter number

For channels to work successfully across NetBIOS, the adapter support at each end must be compatible. IBM MQ allows you to control the choice of LAN adapter (LANA) number by using the AdapterNum value in the NETBIOS stanza of our qm.ini file and by specifying the -a parameter on the runmqlsr command.

The default LAN adapter number used by IBM MQ for NetBIOS connections is 0. Verify the number being used on the system as follows:

On Windows, it is not possible to query the LAN adapter number directly through the operating system. Instead, we use the LANACFG.EXE command-line utility, available from Microsoft. The output of the tool shows the virtual LAN adapter numbers and their effective bindings. For further information about LAN adapter numbers, see the Microsoft Knowledge Base article 138037 HOWTO: Use LANA Numbers in a 32-bit Environment.
