IOLAN SDS/SCS/STS/MDC User’s Guide, Version 4.0

The 

 tab configures Active Standby (SCS models only), DNS update, IPv6 Advertising 

Router settings, and the Ethernet interface(s) hardware speed and duplex.

Configure the parameters in the 

 tab only if:

z

you have already set up Dynamic DNS with DynDNS.com 

z

you want to enable Active Standby (SCS models only)

z

you want to specify the line speed and duplex

z

you want the IOLAN to act as an IPv6 Advertising Router

Configure the appropriate parameters:

When this parameter is set, the IOLAN will provide the DHCP/DHCPv6 server 
with a fully qualified domain name (FQDN), so that the DHCP/DHCPv6 server 
can update the network's DNS server with the newly assigned IP address.

Default: Disabled

(SCS models only) A domain prefix to uniquely identify the Ethernet interface 
to the DNS when the IOLAN has two Ethernet interfaces. The FQDN that is 
sent to the DNS will be one of the following formats, depending on what is 
configured in the System Settings section on the 

 tab: 

z

<Server Name>.<Domain Prefix>.<Domain Name>

z

Field Format: Maximum 8 alphanumeric characters

(SCS models only) 

 permits the grouping of Ethernet LAN 

connections to provide for link failover. Both Ethernet connections will have 
the same Ethernet MAC address. Active standby refers to the process by which 
a failure of one interface can be automatically overcome by having its traffic 
routed to the other interface. 

Default: Disabled
