l Network speed.
If the nShield Connect is already configured, you can update the displayed values.
If you ever change any of the IP addresses on the nShield Connect, you must update the configuration
of all the clients that work with it to reflect the new IP addresses.
By default, the hardserver listens on all interfaces. However, you can choose to set specific
network interfaces on which the hardserver listens. This may be useful in cases such as if one
of the Ethernet interfaces is to be connected to external hosts. See the
User Guide
for more
information.
9.2.1.1 IPv4 and IPv6
Support for IPv6 is in addition to IPv4. Both Ethernet interfaces can be configured to support:
l IPv4 only
l IPv4 and IPv6 – dual stack
l IPv6 only.
Interface#1 is enabled by default and cannot be disabled. Interface #2 is disabled by default
and can be enabled and disabled.
9.2.1.1.1 IPv6 Addresses
An IPv4 address is 32 bits long and typically represented as 4 octets, for example 192.168.0.1. An
IPv6 address is 128 bits long and is made up of a subnet prefix (n bits long) and an interface ID (128 -
n bits long).
An IPv6 address and its associated subnet is typically represented by the notation
ipv6-address/prefix-
length
, where:
l
ipv6-address
is an IPv6 address represented in any of the notations described below
l
prefix-length
is a decimal value specifying how many of the leftmost contiguous bits of the address
make up the prefix.
The IPv6 address notation mirrors the way subnets are represented in the IPv4 Classless Inter-Domain
Routing (CIDR) notation.
9.2.1.1.2 IPv6 Address notation
An nShield Connect will accept an IPv6 address if it is entered in one of the forms shown below and if
the address is valid for context in which it is used. There are two conventional forms for representing
IPv6 addresses as text strings:
1. The long representation is x:x:x:x:x:x:x:x,where the x's are fields containing the hexadecimal
characters (0 to ffff) for each 16 bits of the address. For example:
