Configuring logical switches to use basic configuration values

Configuring logical switches to use basic configuration values
All switches in the fabric are configured to use the same basic configuration values. When you
create logical switches, the logical switches might have different configuration values than the
default logical switch. Use the following procedure to ensure that newly created logical switches
have the same basic configuration values as the default logical switch.
NOTE
For most users, you do not need to run this procedure. Contact your switch service provider to
determine if you need to use this procedure.
You need to run this procedure only once on each chassis, after you enable Virtual Fabrics but
before you create logical switches. The configuration settings are then preserved across reboots
and firmware upgrades and downgrades.
Use the following procedure to configure logical switches to use basic configuration values:
1. Connect to the physical chassis and log in using an account with the chassis-role permission.
2. Enter the configureChassis command to ensure that newly created logical switches have the
same basic configuration values as the default logical switch:
configurechassis
3. Enter n at the prompts to configure system and cfgload attributes. Enter y at the prompt to
configure custom attributes.
System (yes, y, no, n): [no] n
cfgload attributes (yes, y, no, n): [no] n
Custom attributes (yes, y, no, n): [no] y
4. Enter the appropriate value at the Config Index prompt. Contact your switch service provider to
determine the appropriate value.
Config Index (0 to ignore): (0..1000) [3]:
Creating a logical switch or base switch
When the logical switch is created, it is automatically enabled and is empty—that is, it does not
have any ports. After creating the logical switch, you must disable the switch to configure it and set
the domain ID. You then assign ports to the logical switch.
Optionally, you can define the logical switch to be a base switch. Each chassis can have only one
base switch.
NOTE
Domain ID conflicts are detected before fabric ID conflicts. If you have both a domain ID conflict and
a fabric ID conflict, only the domain ID conflict is reported.
Use the following procedure to create a logical switch or a base switch:
1. Connect to the physical chassis and log in using an account with the chassis-role permission.
2. Enter the lsCfg command to create a logical switch:
lscfg --create fabricID [ -base ] [ -force ]
