ftp ipv6

Syntax

ftp ipv6 [ remote-system [ port-number ] [ source source-ipv6-address ] [ -i interface-type interface-number ] ]

View

User view

Parameter

remote-system: IPv6 address or host name (a string a 1 to 46 characters) of the destination device.

port-number: Port through which the FTP client is connected to the FTP server. It is in the range of 0 to 65535 and defaults to 21.

source source-ipv6-address: Specifies the source address of the FTP packets to be sent. The source address specified must be the IPv6 address configured for the access controller.

-i interface-type interface-number: Specifies the type and number of an outgoing interface. It is required when the destination address is a link-local address.

Description

Use ftp ipv6 to initiate a control connection to the remote FTP server and enter FTP client view.

Note the following:

·     If you execute this command without specifying any argument, you will enter FTP client view but will not be logged into the FTP server.

·     If the command is executed with arguments specified, the system will prompt you for username and password for logging into the FTP server. If you enter the correct username and password, you will be logged into the FTP server and enter FTP client view; otherwise, the login will fail.

Example

# Connect to the remote FTP server whose address is 3000::200.

<Sysname> ftp ipv6 3000::200

Trying 3000::200 ...

Press CTRL+K to abort

Connected to 3000::200.

220 Welcome!

User(3000::200:(none)): MY_NAME

331 Please specify the password.

Password:

230 Login successful.

open ipv6

Syntax

open ipv6 remote-system [ port-number ] [ -i interface-type interface-number ]

View

FTP client view

Parameter

remote-system: IPv6 address or host name (a string a 1 to 46 characters) of the destination device.

port-number: Number of the TCP port providing FTP service on the remote device. It is in the range of 0 to 65535 and defaults to 21.

-i interface-type interface-number: Specifies the type and number of the outgoing interface. You must specify this argument if the destination address is a link-local address.

Use open ipv6 to log in to the FTP server in FTP client view.

Before you can log in, the system prompts you to enter the login username and password. If the username and password are correct, you can log in successfully; otherwise, the login fails.

Example

# In FTP client view, log in to the FTP server whose IPv6 address is 3000::200.

<Sysname> ftp ipv6

[ftp] open ipv6 3000::200

Trying 3000::200 ...

Press CTRL+K to abort

Connected to 3000::200.

220 Welcome!

User(3000::200:(none)): MY_NAME

331 Please specify the password.

Password:

230 Login successful.

ping ipv6

Syntax

ping ipv6 [ -a source-ipv6-address | -c count | -m interval | -s packet-size | -t timeout ]* remote-system [ -i interface-type interface-number ]

View

Any view

Parameter

-a source-ipv6-address: Specifies source IPv6 address.

-c count: Specifies the number of times that the ICMPv6 ECHO-REQUEST packets are sent, in the range of 1 to 4294967295. The default value is 5.

-m interval: Specifies the interval (in milliseconds) to send ICMPv6 ECHO-RESPONSE packets, in the range of 1 to 65535. The default value is 200 ms.

·     If a response from the destination is received within the timeout time, the interval to send the next ECHO-REQUEST equals the actual response period plus the value of interval.

·     If no response from the destination is received within the timeout time, the interval to send the next ECHO-REQUEST equals to the timeout value plus the value of interval.

-s packet-size: Specifies length (in bytes) of ICMPv6 ECHO-REQUEST packets, in the range of 20 to 8100 and defaults to 56.

-t timeout: Specifies the timeout value (in milliseconds) of the ICMPv6 ECHO-REQUEST packets, in the range of 0 to 65535 and defaults to 2000.

remote-system: IPv6 address or host name (a string a 1 to 46 characters) of the destination device.

-i interface-type interface-number: Specifies the egress interface by its type and number. This parameter must be specified when the destination address is the link local address or a multicast address.

Description

Use ping ipv6 to test whether the destination is accessible.

Example

# Test whether destination 2001::1 is accessible.

<Sysname> ping ipv6 2001::1

  PING 2001::1 : 56  data bytes, press CTRL_C to break

    Reply from 2001::1

    bytes=56 Sequence=1 hop limit=64  time = 20 ms

    Reply from 2001::1

    bytes=56 Sequence=2 hop limit=64  time = 0 ms

    Reply from 2001::1

    bytes=56 Sequence=3 hop limit=64  time = 0 ms

    Reply from 2001::1

    bytes=56 Sequence=4 hop limit=64  time = 0 ms

    Reply from 2001::1

    bytes=56 Sequence=5 hop limit=64  time = 0 ms

 

  --- 2001::1 ping statistics ---

    5 packet(s) transmitted

    5 packet(s) received

    0.00% packet loss

    round-trip min/avg/max = 0/4/20 ms

The "hop limit" field in this prompt information has the same meaning as the "ttl" field in the prompt information displayed by the IPv4 ping command, indicating the TTL value in the ICMPv6 ECHO-REQUEST packets.

telnet ipv6
