change self-unit to { unit-id | auto-numbering }
View
System view
Parameters
unit-id: Changes
the unit ID of the current switch to a specified value which is in the range of
1 to 8.
auto-numbering: Changes the numbering mode of unit ID on
the current switch to automatic
numbering mode.
Description
Use the change self-unit command to
change the unit ID of the current switch. If a user telnets to an IRF fabric,
only the switch connecting with the network of the telnet user responds to the
telnet request, and this switch is the current switch. You can use the display
irf-fabric command to identify which device is the current device in an IRF
fabric.
When you change the unit ID of the current
switch, note the following:
l
If the modified unit ID is not used in the IRF
fabric, the system sets its priority to 5 and saves it in the Flash memory of
the current switch.
l
If the modified unit ID is being used, the
system prompts you to confirm if you really want to change the unit ID. If you
choose to change it, the existing unit ID is replaced and the priority is set to
5. The original device which uses this unit ID will be auto-numbered again. Then
you can use the fabric save-unit-id command to save the modified unit ID
into the Flash memory of the current switch.
l
If auto-numbering is selected, the system
sets the unit priority to 10. You can use the fabric save-unit-id
command to save the modified unit ID into the Flash memory 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.
l
If you do not bring up the fabric port, you
cannot change the unit ID of a switch.
l
After the unit ID of a device is changed, the unit
ID-related information of this device in the configuration file of the fabric will
be upgraded automatically. If the unit ID of a device changes from 2 to 4, the port
description of this device in the configuration file automatically changes from
2/0/x to 4/0/x.

Parameters
unit-id1: Current
unit ID.
unit-id2: New
unit ID.
auto-numbering: Changes the numbering
mode of unit ID on a specified switch (not the current switch) to automatic numbering mode.
Description
Use the change unit-id command to configure
the unit ID of a specified 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.
When you change the unit ID of a switch in
an IRF fabric, note the following:
l
If the modified unit ID of the switch is not used
in the fabric, the system sets its priority to 5 and saves it in the Flash
memory of the switch.
l
If the modified unit ID is being used, the
system prompts you to confirm if you really want to change the unit ID. If you
choose to change it, the existing unit ID is replaced and the priority is set
to 5. The original device which uses this unit ID will be auto-numbered again. Then
you can use the fabric save-unit-id command to save the modified unit ID
into the Flash memory of the switch.
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 Flash memory of
the switch.
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 After the unit ID of a device is changed, the unit ID-related
information of this device in the configuration file of the fabric will be
upgraded automatically. If the unit ID of a device changes from 2 to 4, the
port description of this device in the configuration file automatically changes
from 2/0/x to 4/0/x.

Parameters
None
Description
Use the fabric member-auto-update
software enable command to enable the IRF automatic fabric function for a
switch.
Use the undo fabric
member-auto-update software enable command to disable the IRF automatic
fabric function for a switch.
By default, the IRF automatic fabric
function for a switch is disabled.
H3C S5600 series switches provide the IRF
automatic fabric function, which enables a candidate switch to automatically
download the software and change the fabric name in case that the software
version and fabric name of the candidate device and that of the device in the
fabric are different, thus reducing the manual maintenance workload.
Caution:
l
You need to enable the IRF automatic fabric
function on all the devices including the candidate switch in the fabric to
enable the candidate switch to download software and discovery neighbors and
thus be added to the fabric normally.
l
If the candidate switch is going to download
software from a unit in an IRF fabric, you are recommended to set the ID of the
unit to 1 to make the candidate switch download the software of correct
version.
l
Before configuring the IRF automatic fabric
function, make sure that the candidate switch has enough Flash space to
download the software.
l
After you configure the IRF automatic fabric
function on Slave, execute the save command to save the configurations
as soon as possible. Otherwise, the device may synchronize the configurations
from Master and restart repeatedly because the configurations on the device are
lost after the device automatically downloads the software and restarts.

Parameters
interface-type interface-number: Type and port number of a fabric port. On an S5600 series Ethernet
switch, only two Cascade ports can be configured as fabric ports.
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.
Establishing an IRF
system requires a high consistency of the configuration of each device. Hence,
before you bring up the fabric port, do not perform any configuration for the
port, and do not enable some functions that affect the IRF (such as TACACS and
VLAN-VPN) for other ports or globally. Otherwise, you cannot bring up the
fabric port. For detailed restrictions, refer to the
error information output by devices.

Description
Use the sysname command to set the

example, if the fabric name of the Ethernet switch is H3C, the prompt character
in user view is <H3C>.
Use the undo sysname command
