Emergency shell commands

File system names, directory names, or file names must be compliant with the naming conventions. For more information about the naming conventions and the methods for specifying the names, see Fundamentals Configuration Guide.

Unless otherwise stated, a file or directory name argument in this document is case insensitive. It must contain the storage medium and cannot contain slot information. The path information might contain multiple levels of directories, each of which can have 1 to 255 characters. The file name alone (without the path information) can have 1 to 255 characters. The entire argument, including the file system name, the path information, and the file name, can have 1 to 511 characters. (In standalone mode.)

Unless otherwise stated, a file or directory name argument in this document is case insensitive. It must contain the file system name and cannot contain chassis or slot information. The path information might contain multiple levels of directories, each of which can have 1 to 255 characters. The file name alone (without the path information) can have 1 to 255 characters. The entire argument, including the file system name, the path information, and the file name, can include 1 to 511 characters. (In IRF mode.)

If the device has a flash memory and a CF card, you can access the flash memory and the CF card in emergency shell mode.

Examples in this chapter use the CF card. A different storage medium might be used on your device.

copy

Use copy to copy a file.

Syntax

copy fileurl-source fileurl-dest

Views

User view

Parameters

fileurl-source: Specifies the file to be copied.

fileurl-dest: Specifies the destination file or directory. If you specify a destination directory, the system uses the name of the source file as the file name.

Usage guidelines

If the destination file already exists, the system prompts whether or not to overwrite it. If you enter Y, the existing file is overwritten. If you enter N, the command is not executed.

Examples

# Copy the file cfa0:/test.cfg. Save the copy to the file cfa0:/testbackup.cfg.

<boot> copy cfa0:/test.cfg cfa0:/testbackup.cfg

Copy cfa0:/test.cfg to cfa0:/testbackup.cfg?[Y/N]:y

Start to copy cfa0:/test.cfg to cfa0:/testbackup.cfg...Done.

# Copy the file cfa0:/test.cfg and save the copy to the file cfa0:/testbackup.cfg. Overwrite the existing file that has the same name as the destination file.

<boot> copy cfa0:/test.cfg cfa0:/testbackup.cfg

Copy cfa0:/test.cfg to cfa0:/testbackup.cfg?[Y/N]:y

cfa0:/testbackup.cfg already exists. Overwrite it?[Y/N]:y

Start to copy cfa0:/test.cfg to cfa0:/testbackup.cfg...Done.

delete

Syntax

delete file-url

Views

User view

Parameters

file-url: Specifies the file to be deleted.

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

Start to delete cfa0:/tt.cfg...Done.

User view

Parameters

system-package: Specifies the .bin system image file in the filesystemname/filename.bin format, for example, cfa0:/startup-system.bin. The filesystemname cannot contain slot information. The file must be saved in the root directory of a file system on the current device. The value string is case insensitive and can have a maximum of 63 characters.

Usage guidelines

This command modifies the main startup image list to include only the boot image and system image. The modification ensures that the device can reboot correctly.

After the Comware system starts up, you can load feature and patch images. For more information, see the chapters about software upgrade and ISSU in Fundamentals Configuration Guide.

Examples

# Load a system image and start the Comware system.

<boot> install load cfa0:/system.bin

Parameters

ip-address: Specifies an IPv4 address in dotted decimal notation.

mask-length: Specifies the length of the subnet mask, in the range of 1 to 31.

mask: Specifies the subnet mask in dotted decimal notation.

Usage guidelines

If you execute this command multiple times, the most recent configuration takes effect.

When the management Ethernet interface is manually shut down, assigning it an IPv4 address or removing its IPv4 address activates it at the same time.

The IP address assigned to the management Ethernet interface must be different from the IP addresses of the other devices on the network.

Examples

# Assign the IPv4 address 192.168.1.1/24 to the management Ethernet interface.

<boot> system-view

[boot] interface m-eth0

Views

Management Ethernet interface view

Parameters

ip-address: Specifies the IPv4 address of an IPv4 gateway in dotted decimal notation.

Usage guidelines

When the device needs to communicate with a device on a remote IPv4 network, you must specify an IPv4 gateway for the management Ethernet interface.

If you execute this command multiple times, the most recent configuration takes effect.

Changing or removing the IPv4 address of the management Ethernet interface deletes the interface's IPv4 gateway configuration.

Examples

# Configure the management Ethernet interface to use the IPv4 gateway 192.168.1.5.

<boot> system-view

[boot] interface m-eth0

[boot-m-eth0] ip gateway 192.168.1.5

Use undo ipv6 address to restore the default.

Syntax

ipv6 address ipv6-address prefix-length

undo ipv6 address

Default

No IPv6 address is assigned to the management Ethernet interface .

Views

Management Ethernet interface view

Parameters

ipv6-address: Specifies an IPv6 address.

prefix-length: Specifies a prefix length in the range of 1 to 127.

Usage guidelines

If you execute this command multiple times, the most recent configuration takes effect.

When the management Ethernet interface is manually shut down, assigning it an IPv6 address or removing its IPv6 address activates it at the same time.

Examples

# Assign the IPv6 address 2001::1/64 to the management Ethernet interface.

<boot> system-view

[boot] interface m-eth0

[boot-m-eth0] ipv6 address 2001::1 64

ipv6 gateway

Use ipv6 gateway to specify an IPv6 gateway for the management Ethernet interface.

Parameters

link-local: Specifies the link-local address of an IPv6 gateway.

Usage guidelines

When the device needs to communicate with a device on a remote IPv6 network, you must specify an IPv6 gateway for the management Ethernet interface.

If you execute this command multiple times, the most recent configuration takes effect.

Changing or removing the IPv6 address of the management Ethernet interface deletes the interface's IPv6 gateway configuration.

Examples

# Configure the management Ethernet interface to use the IPv6 gateway FE80::BAAF:67FF:FE27:DCD0.

<boot> system-view

Syntax

mkdir directory

Views

User view

Parameters

directory: Specifies a directory.

Usage guidelines

You can create a directory only in an existing directory. For example, to create the cfa0:/test/mytest directory, the directory test must already exist.

The name of the directory to be created must be unique in the parent directory.

Examples

# Create a directory named test in the root directory of the cfa0: file system.

<boot> mkdir cfa0:/test

Directory cfa0:/test created.

# Create a directory named subtest in the cfa0:/test directory.

reset ssh public-key

Use reset ssh public-key to delete all SSH server public keys saved on the device.

Syntax

reset ssh public-key

Views

User view

Usage guidelines

The first time you use the ssh2 command to connect to an SSH server, the device saves the server's public key locally. The device can then use the public key to authenticate the server when you connect to the server from the device again. If the server changes its public key, the public keys will not match anymore and you cannot connect to the server. To solve this problem, use this command to delete all SSH server public keys saved on the device.

Examples

# Delete all SSH server public keys saved on the device.

<boot> ssh2 192.168.1.59
