DH Key pair used by SSL servers:
This is a private/public key pair that is used by
some cipher suites to encrypt the SSL/TLS handshaking messages.
The key or certificate notation changes from
factory
or
none
to
user
when the
GW EIP/ASCII... is secure.

EtherNet/IP stack
The EtherNet/IP stack management settings are advanced parameters that should only be
changed by a qualified professional. The default parameters are recommended for most
systems. These settings should only be modified for networks that require special attention.

TTL (time to live) network value:
The TTL network value is the network routing parameter
that allows EtherNet/IP messages to be routed between different subnets. A TTL network
value of
1
, the default, allows the messages to be routed over one network “hop”. A TTL
network value of
2
allows two hops and so on.
Multicast IP address allocation control:
The Multicast IP address allocation control
defines how Class 1 multicast addresses are allocated. When
Automatic
(default) is
selected, the GW EIP/ASCII gateway uses the standard automatic multicast address
mechanism. When
User Defined
is selected, the GW EIP/ASCII... gateway allocates the
multicast addresses based on the user settings.
User defined number of multicast IP addresses:
If Multicast IP address allocation
control is set to
User Defined
, the GW EIP/ASCII... uses the configured number of multicast
IP addresses.
User defined multicast start IP address:
If Multicast IP address allocation control is set
to
User Defined
, the GW EIP/ASCII... begins its multicast IP address range at the value
entered.
Session encapsulation timeout:
The GW EIP/ASCII... waits the designated time in
seconds with no activity before timing out a session. A value of
0
disables the timeout
functionality.
Possession of the private portion of the key pair allows an eavesdropper to decrypt traffic
on SSL/TLS connections that use DH encryption during handshaking.
Certificates and keys to be uploaded to the GW EIP/ASCII... must be in the .DER binary
file format, not in the .PEM ASCII file format. (The openssl tools can create files in either
format and can convert files back and forth between the two formats.)
