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 must contain the file system name and cannot contain file system location information. The path information can 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 can have 1 to 511 characters.

ping ipv6

Use ping ipv6 to check the connectivity to an IPv6 address.

Syntax

ping ipv6 [ -c count | -s size ] * ipv6-address

Views

Any view

Parameters

-c count: Specifies the number of ICMPv6 echo requests to send, in the range of 1 to 2147483647. The default is 5.

-s size: Specifies the length (in bytes) of each ICMPv6 echo request, in the range of 20 to 8100. The default is 56.

Ipv6-address: Specifies the IPv6 address of the destination.

Usage guidelines

When you execute the ping ipv6 command, the device sends ICMPv6 echo requests to the destination. You can press Ctrl+C to abort the ping operation.

Examples

# Check the connectivity to the destination 2001::2.

<boot> ping ipv6 2001::2

ping ipv6 2001::2

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

login as:client001
