Emergency shell commands

Unless otherwise stated, a file name or path argument in this document is case insensitive, and must indicate the storage medium and contain no slot information. The path information might contain multiple levels of directories, and each can include 1 to 255 characters. The file name alone (without the path information) can include 1 to 255 characters. The argument, including the storage medium, the path information, and the file name, can include 1 to 511 characters.

Examples in this chapter use the flash memory. The device might have a different storage medium.

User view

Parameters

system-package: Specifies the name of the system image, a case-insensitive string of 1 to 63 characters. This file must be saved in the root directory of the current member device's storage medium, with the extension .bin. The file name must indicate the storage medium and cannot contain slot information, for example, flash:/startup-system.bin.

Usage guidelines

When you execute this command, the system modifies the main startup software image set to include only the boot image and system image so the device can reboot correctly.

After the Comware system is started, 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.

Related commands

quit

ip address

Use ip address to assign an IPv4 address to the management Ethernet port.

Use undo ip address to restore the default.

Syntax

ip address ip-address { mask-length | mask }

undo ip address

Default

The management Ethernet port has no IPv4 address.

Views

Management Ethernet port view

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

The management Ethernet port can have only one IPv4 address. If you execute this command multiple times, the most recent configuration takes effect.

When the management Ethernet port 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 port must be different from the IP addresses of the other devices on the network.

Examples

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

<boot> system-view

[boot] interface m-eth0

[boot-m-eth0] ip address 192.168.1.1 24

ip gateway

Use ip gateway to specify an IPv4 gateway for the management Ethernet port.

Use undo ip gateway to restore the default.

Syntax

ip gateway ip-address

undo ip gateway

Default

The management Ethernet port has no IPv4 gateway configured.

Views

Management Ethernet port view

Parameters

ip-address: Specifies an IPv4 gateway address 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 port.

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

Changing or removing the IPv4 address of the management Ethernet port removes the port's IPv4 gateway configuration.

Examples

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

<boot> system-view

[boot] interface m-eth0

[boot-m-eth0] ip gateway 192.168.1.5

ipv6 address

Use ipv6 address to assign an IPv6 address to the management Ethernet port.

Use undo ipv6 address to restore the default.

Syntax

ipv6 address ipv6-address prefix-length

undo ipv6 address

Default

The management Ethernet port has no IPv6 address.

Views

Management Ethernet port view

Parameters

ipv6-address: Specifies an IPv6 address.

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

Usage guidelines

The management Ethernet port can have only one IPv6 address. If you execute this command multiple times, the most recent configuration takes effect.

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

Examples

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

<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 port.

Use undo ipv6 gateway to restore the default.

Syntax

ipv6 gateway link-local

undo ipv6 gateway

Default

The management Ethernet port has no IPv6 gateway configured.

Views

Management Ethernet port view

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 port.

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

Changing or removing the IPv6 address of the management Ethernet port removes the port's IPv6 gateway configuration.

Examples

# Configure the management Ethernet port to use FE80::BAAF:67FF:FE27:DCD0.

<boot> system-view

[boot] interface m-eth0

[boot-m-eth0] ipv6 gateway fe80::baaf:67ff:fe27:dcd0

mkdir

Syntax

mkdir directory

Views

User view

Parameters

directory: Specifies a directory name.

Usage guidelines

The path must already exist. For example, to create the flash:/test/mytest directory, the directory test must already exist on the Flash.

The name for the new directory must be unique in the upper-level directory.

Examples

# Create a directory named test in the current directory.

<boot> mkdir flash:/test

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 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 server public keys saved on the device.

Examples

# Delete all server public keys saved on the device.

<boot> ssh2 192.168.1.59
