IPv6 management (IPv6 host support)
SNTP over IPv6
To enable the device to send SNTP packets over IPv6, enter a command such as the following at
the Global CONFIG level of the CLI.
TurboIron(config)#sntp server ipv6 2001:DB8::400
Syntax: sntp server ipv6 <ipv6-address>
• The< ipv6-address> is the IPv6 address of the SNTP server. When you enter the IPv6 address,
you do not need to specifry the prefix length. A prefix length of 128 is implied.
Secure Shell, SCP, and IPv6
Secure Shell (SSH) is a mechanism that allows secure remote access to management functions on
the device. SSH provides a function similar to Telnet. You can log in to and configure the device
using a publicly or commercially available SSH client program, just as you can with Telnet. However,
unlike Telnet, which provides no security, SSH provides a secure, encrypted connection to the
device.
To open an SSH session between an IPv6 host running an SSH client program and the device, open
the SSH client program and specify the IPv6 address of the device. For more information about
configuring SSH on the device, refer to
“SSH version 2 support” on page 119.
IPv6 Telnet
Telnet sessions can be established between a device to a remote IPv6 host, and from a remote
IPv6 host to the device using IPv6 addresses.
The telnet command establishes a Telnet connection from a device to a remote IPv6 host using the
console. Up to five read-access Telnet sessions are supported on the router at one time.
Write-access through Telnet is limited to one session, and only one outgoing Telnet session is
supported on the router at one time. To see the number of open Telnet sessions at any time, enter
the show telnet command.
Example
To establish a Telnet connection to a remote host with the IPv6 address of 2001:DB8:3de2:c37::6,
enter the following command.
TurboIron#telnet 2001:DB8:3de2:c37::6
Syntax: telnet <ipv6-address> [ <port-number> | outgoing-interface ethernet <port> | ve
<number>]
• The <ipv6-address> parameter specifies the address of a remote host. You must specify this
address in hexadecimal using 16-bit values between colons as documented in RFC 2373.
• The <port-number> parameter specifies the port number on which the device establishes the
Telnet connection. You can specify a value between 1 - 65535. If you do not specify a port
number, the device establishes the Telnet connection on port 23.
• If the IPv6 address you specify is a link-local address, you must specify the outgoing-interface
Ethernet <port> | ve <number> parameter. This parameter identifies the interface that must
be used to reach the remote host. If you specify an Ethernet interface, you must also specify
the port number associated with the interface. If you specify a VE interface, also specify the VE
number.
