Setting A Unit Id For A Switch - H3C S5600 Series Operation Manual

To do...
Specify the fabric port of a switch
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
configure some functions that affect the IRF for other ports or globally. Otherwise, you cannot
enable the fabric port. For detailed restrictions refer to the error information output by devices.
After an IRF fabric is created, you are not recommended to enable the Burst function on any fabric
device. For the introduction to the Burst function, refer to the QoS-QoS Profile part in this manual.
To split a fabric, you can simply remove the cables used to form the fabric or disable the fabric
using the undo fabric-port enable command.
If you need to configure an IRF fabric as a DHCP server, DHCP relay or DHCP client, configure the
UDP Helper function in the fabric at the same time to ensure that the client can successfully obtain
an IP address. For the configuration of the UDP Helper function, refer to the UDP Helper part in this
manual.

Setting a Unit ID for a Switch

FTM will automatically number the switches to constitute an IRF fabric by default, so that each switch
has a unique unit ID in the fabric. You can use the command in the following table to set unit IDs for
switches. Make sure to set different unit IDs for different switches in an IRF fabric. Otherwise, FTM will
automatically number the switches with the same unit ID.
Follow these steps to set a unit ID for a switch:
To do...
Enter system view
Set a unit ID for the switch
If you do not enable the fabric port, you cannot change the unit ID of the local switch.
After an IRF fabric is established, you can use the following command to change the unit IDs of the
switches in the IRF fabric.
Follow these steps to set a unit ID to a new value:
Use the command...
fabric-port interface-type
interface-number enable
Use the command...
system-view
change self-unit to { unit-id |
auto-numbering }
1-7
Required
Not specified by default
Remarks
—
Optional
By default, the unit ID of a switch that belongs
to no IRF fabric is 1. The unit ID of a switch
belonging to an IRF fabric is assigned by FTM.
Unit ID ranges from 1 to 8.
