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 MPU's storage medium, with the extension .bin. The file name must indicate the storage medium and cannot contain chassis or slot information, for example, flash:/startup-system.bin. (In IRF mode.)

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 normally.

After the Comware system is started, you can load feature images and patch images as described in the chapters about software upgrade and ISSU in Fundamentals Configuration Guide.

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 }

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 0 to 32.

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.

The IPv4 gateway address must be on the same segment as the IPv4 address of the management Ethernet port.

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

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

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 128.

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.

The IPv6 gateway address must be on the same segment as the IPv6 address of the management Ethernet port.

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

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

Examples

# Configure the management Ethernet port to use IPv6 gateway 2002::1.

<boot> system-view

[boot] interface m-eth0

[boot-m-eth0] ipv6 gateway 2002::1

mkdir

reset ssh public-key

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

Usage guidelines

When you use the ssh2 command to connect to an SSH server for the first time, the device saves a copy of the server's public key locally so it can 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> reset ssh public-key
