change self-unit to { unit-id | auto-numbering }
View
System view
Parameter
unit-id:
Unit ID to be set to.
auto-numbering: Changes the unit ID automatically.
Description
Use the change self-unit command to
change the unit ID of the current switch.
By default, the unit ID of a switch that belongs
to no IRF fabric is 1. After a switch is added to an IRF fabric, it is
automatically numbered through FTM function with its unit ID ranging from 1 to
8.
If you do not
enable the fabric port, you cannot change the unit ID of a local switch.
Example
# Configure the unit
ID of the current switch to be automatically numbered.

View
System view
Parameter
unit-id1: Current
unit ID.
Unit-id2: New
unit ID.
auto-numbering: Changes the unit ID automatically.
Description
Use the change unit-id command to configure
the unit ID of a switch in an IRF fabric to a new value. By default, when a switch
is added to an IRF fabric, it uses the automatically assigned unit ID.
l
If the modified unit ID does not exist in the
fabric, the system sets its priority to 5 and saves it in the unit Flash
memory.
l
If the modified unit ID is an existing one, the
system prompt you to confirm if you really want to change the unit ID. If you
choose to change, the existing unit ID is replaced and the priority is set to
5. Then you can use the fabric save-unit-id command to save the modified
unit ID into the unit Flash memory and clear the information about the existing
one.
l
If auto-numbering is selected, the system
reserves the unit ID and sets the unit priority to 10. You can use the fabric
save-unit-id command to save the modified unit ID into the unit Flash
memory and clear the information about the existing one.
l
Unit IDs in an IRF fabric are not always
arranged in order of 1 to 8.
l
Unit IDs in an IRF fabric can be inconsecutive.
l
It is recommended that you reboot the device after
you change the Unit ID and synchronize the configuration.
Related command: fabric save-unit-id.

Parameter
interface-type: Type of the port to be configured as a fabric port. Note that only
GigabitEthernet ports can be configured as fabric ports.
interface-number: Number of the port to be configured as a fabric port.
Description
Use the fabric-port enable command
to configure a specified port as a fabric port.
Use the undo
fabric-port enable command to disable the fabric port function for a port. When
the last fabric port on a switch is disabled, the fabric function is disabled globally.
l
Establishing an IRF system requires a high
consistency of the configuration of each device. Hence, before you enable the
fabric port, do not perform any configuration for the port, and do not enable
some functions that affect the IRF (such as TACACAS and VLAN-VPN) for other
ports or globally. Otherwise, you cannot enable the fabric port. For detailed
restrictions refer to the error information output by devices.
l
When you have enabled fabric port function for a
fabric port group, if you need to change the fabric port group, you must
disable the fabric function of the current fabric port group before you execute
the enable command on another group. Otherwise, the system will prompt that the
current fabric port group is in use, you cannot change the fabric port group.
