IPv6 management (IPv6 host support)
Establishing a Telnet session from an IPv6 host
To establish a Telnet session from an IPv6 host to the device, open your Telnet application and
specify the IPv6 address of the device.
Configuring name-to-IPv6 address resolution using IPv6 DNS resolver
The Domain Name Server (DNS) resolver feature lets you use a host name to perform Telnet and
ping commands. You can also define a DNS domain on a device and thereby recognize all hosts
within that domain. After you define a domain name, the device automatically appends the
appropriate domain to the host and forwards it to the domain name server.
For example, if the domain “newyork.com” is defined on a device, and you want to initiate a ping to
host “NYC01” on that domain, you need to reference only the host name in the command instead
of the host name and its domain name. For example, you could enter either of the following
commands to initiate the ping.
TurboIron#ping ipv6 nyc01
TurboIron#ping ipv6 nyc01.newyork.com
Defining an IPv6 DNS entry
IPv6 defines new DNS record types to resolve queries for domain names to IPv6 addresses, as well
as IPv6 addresses to domain names. Devices running IPv6 software support AAAA DNS records,
which are defined in RFC 1886.
AAAA DNS records are analogous to the A DNS records used with IPv4. They store a complete IPv6
address in each record. AAAA records have a type value of 28.
To establish an IPv6 DNS entry for the device, enter the following command.
TurboIron(config)#ipv6 dns domain-name companynet.com
Syntax: [no] ipv6 dns domain-name <domain name>
To define an IPv6 DNS server address, enter the following command.
TurboIron(config)#ipv6 dns server-address 2001:DB8::1
Syntax: [no] ipv6 dns server-address <ipv6-addr> [<ipv6-addr>] [< ipv6-addr>] [< ipv6-addr>]
As an example, in a configuration where ftp6.companynet.com is a server with an IPv6 protocol
stack, when a user pings ftp6.companynet.com, the device attempts to resolve the AAAA DNS
record. In addition, if the DNS server does not have an IPv6 address, as long as it is able to resolve
AAAA records, it can still respond to DNS queries.
Using the IPv6 copy command
The copy command for IPv6 allows you to do the following:
• Copy a file from a specified source to an IPv6 TFTP server.
• Copy a file from an IPv6 TFTP server to a specified destination.
Copying a file to an IPv6 TFTP server
You can copy a file from the following sources to an IPv6 TFTP server:
