Upgrade method	Software types	Remarks
Upgrading from the CLI by using the boot loader method	· Boot image · System image · IPE package · BootWare image	This method is disruptive. You must reboot the entire switch to complete the upgrade.
Upgrading by using install commands	· Patch image · Feature image	This method does not require the reboot of the switch and has a small impact on services.
Performing an ISSU from the CLI	· Boot image · System image · IPE package	This method is supported on an IRF fabric. This method has a small impact on services.
Upgrading from the BootWare menu	· IPE package · BootWare image	Use this method when the device cannot start up correctly. To use this method, you must log in to the switch through the console port.

Setting up an upgrade environment

Set up an upgrade environment as follows:

1. Use the console cable to connect the serial port on the PC and the console port on the switch.

2. Use the network cable to connect the network port on the PC and the management Ethernet port on the switch.

NOTE:

If the switch does not have a management Ethernet port, connect the network port on the PC and an Ethernet interface on the switch.

Figure 1 Setting up an upgrade environment

Logging in to the switch

To upgrade software from the BootWare menu, you can log in to the switch through only the console port.

To upgrade software at the CLI, you can log in to the switch through either the console port or the management Ethernet port. If the device does not have a management Ethernet port, you can log in to the switch through a VLAN interface or Layer 3 Ethernet interface. The procedure for configuring a VLAN interface or Layer 3 Ethernet interface for login is similar to that for configuring the management Ethernet port.

Logging in to the switch through the console port

1. Run a terminal emulation program on the PC and configure the following parameters:

¡ Bits per second—9600.

¡ Data bits—8.

¡ Stop bits—1.

¡ Parity—None.

¡ Flow control—None.

2. Power on the switch. The following information is displayed. After you press Enter, the command prompt appears (such as <Sysname>).

****************************************************************************

* Without the owner's prior written consent, *

* no decompiling or reverse-engineering shall be allowed. *

****************************************************************************

Line aux0 is available.

Press ENTER to get started.

<Sysname>%Mar 30 09:52:58:243 2022 H3C SHELL/5/SHELL_LOGIN:TTY logged in from aux0.

Logging in to the switch through the management Ethernet port

1. Log in to the switch through the console port, enter system view, and enable the Telnet service.

<Sysname> system-view

[Sysname] telnet server enable

2. Assign an IP address to the management Ethernet port. The IP address must be in the same network segment as the IP address of the PC.

[Sysname] interface M-GigabitEthernet 0/0/0

[Sysname-M-GigabitEthernet0/0/0] ip address 192.168.0.105 24

[Sysname-M-GigabitEthernet0/0/0] quit

3. Configure common attributes for the VTY line.

[Sysname] line vty 0 63

[Sysname-line-vty0-63] authentication-mode none

[Sysname-line-vty0-63] user-role network-admin

[Sysname-line-vty0-63] idle-timeout 0 0

[Sysname-line-vty0-63] quit

4. Open the terminal emulation program on the PC, and log in to the switch through Telnet.

Checking the storage space

Verify that the switch has sufficient storage for the upgrade file.

If the free storage space is not sufficient on the switch, delete unused files.

If an .ipe file is used, make sure the free storage space is greater than the sum of the size of the .ipe file and the size of the .bin files decompressed.

Checking the storage space at the CLI

Identifying the storage medium

# Use the display boot-loader command to identify the storage medium. The following command output shows that the storage medium is the flash memory.

The command output might vary by switch model. This section uses an S10500 switch as an example.

<Sysname> display boot-loader

Software images on slot 1:

Current software images:

flash:/S10500-CMW710-BOOT-R7596P10.bin

Deleting unused files

· Use the delete /unreserved command to delete an unused file permanently.

<Sysname> delete /unreserved boot.bin

The file cannot be restored. Delete flash:/boot.bin? [Y/N]:y

Deleting the file permanently will take a long time. Please wait...

Deleting file flash:/boot.bin...Done.

· Use the delete command to delete an unused file.

# Delete an unused file.

<Sysname> delete boot.bin

Delete flash:/boot.bin? [Y/N]:y

Deleting file flash:/boot.bin...Done.

# Clear the recycle bin.

<Sysname> reset recycle-bin

Clear flash:/boot.bin? [Y/N]:y

Clearing file flash:/boot.bin... Done

NOTE:

To delete a file permanently, use the delete /unreserved command. If you use the delete command, the file is moved to the recycle bin and still occupies the storage space. To release the storage space, you must execute the reset recycle-bin command in the file's original directory.
