Restricting Web management access to an IPv6 host
You can restrict Web management access to the device to the IPv6 host whose IP address you specify. No other device except the one
with the specied IPv6 address can access the Web Management Interface.
Example
Brocade(config)#web client ipv6 3000:2383:e0bb::2/128
Syntax: web client ipv6 ipv6-address
the ipv6-address you specify must be in hexadecimal format using 16-bit values between colons as documented in RFC 2373.
Conguring 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 dene a
DNS domain on a Brocade device and thereby recognize all hosts within that domain. After you dene a domain name, the Brocade
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 dened on a Brocade 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.
device#ping ipv6 nyc01
device#ping ipv6 nyc01.newyork.com
Dening an IPv6 DNS entry
IPv6
denes new DNS record types to resolve queries for domain names to IPv6 addresses, as well as IPv6 addresses to domain
names. Brocade devices running IPv6 software support AAAA DNS records, which are dened 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 dene an IPv6 DNS server address, enter command such as the following:
device(config)#ipv6 dns server-address 2001:DB8::1
Syntax: [no] ipv6 dns server-address ipv6-addr [ ipv6-addr ] [ ipv6-addr ] [ ipv6-addr ]
The ipv6 dns server-address parameter sets IPv6 DNS server addresses.
As an example, in a conguration where ftp6.companynet.com is a server with an IPv6 protocol stack, when a user pings
ftp6.companynet.com, the Brocade 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.
Pinging an IPv6 address
NOTE
This section describes the IPv6ping command. For details about IPv4 ping , refer to the FastIron Ethernet Switch Layer 3
Routing Conguration Guide.
The ping command allows you to verify the connectivity from a Brocade device to an IPv6 device by performing an ICMP for IPv6 echo
test.
