IPv6 management (IPv6 host support)

• The port-number parameter specifies the port number on which the PowerConnect device
establishes the Telnet connection. You can specify a value between 1 - 65535. If you do not
specify a port number, the PowerConnect 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.
Establishing a Telnet session from an IPv6 host
To establish a Telnet session from an IPv6 host to the PowerConnect 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 PowerConnect device and thereby
recognize all hosts within that domain. After you define a domain name, the PowerConnect 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 PowerConnect 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.
PowerConnect# ping ipv6 nyc01
PowerConnect# 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. PowerConnect 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.
PowerConnect(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.
PowerConnect(config)# ipv6 dns server-address 200::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 PowerConnect 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.
