IPv6 management features
7
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 Dell 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.
IPv6 ping
The ping command allows you to verify the connectivity from a Dell PowerConnect device to an IPv6
device by performing an ICMP for IPv6 echo test.
For example, to ping a device with the IPv6 address of 2001:3424:847f:a385:34dd::45 from the
Dell PowerConnect device, enter the following command:
PowerConnect#ping ipv6 2001:3424:847f:a385:34dd::45
Syntax: ping ipv6 <ipv6-address> [outgoing-interface [<port> | ve <number>]] [source
<ipv6-address>] [count <number>] [timeout <milliseconds>] [ttl <number>] [size
<bytes>] [quiet] [numeric] [no-fragment] [verify]
[data <1-to-4 byte hex>] [brief]
• The <ipv6-address> parameter specifies the address of the router. You must specify this
address in hexadecimal using 16-bit values between colons as documented in RFC 2373.
• The outgoing-interface keyword specifies a physical interface over which you can verify
connectivity. If you specify a physical interface, such as an Ethernet interface, you must also
specify the port number of the interface. If you specify a virtual interface, such as a VE, you
must specify the number associated with the VE.
• The source <ipv6-address> parameter specifies an IPv6 address to be used as the origin of
the ping packets.
NOTE
The outgoing-interface and source options are available only on Layer 3 code and not on Layer
2 code.
• The count <number> parameter specifies how many ping packets the router sends. You can
specify from 1 - 4294967296. The default is 1.
• The timeout <milliseconds> parameter specifies how many milliseconds the router waits for a
reply from the pinged device. You can specify a timeout from 1 - 4294967294 milliseconds.
The default is 5000 (5 seconds).
• The ttl <number> parameter specifies the maximum number of hops. You can specify a TTL
from 1 - 255. The default is 64.
