The following options are available with this command:
◗ Master Network Server Configuration
Establishing a master/slave relationship between network servers facilitates
efficient Wide Area Network management by reducing the amount of traffic
between two subnets on the same network, as well as providing a single
network server responsible for all Strix devices within its subnet. This feature
enables a Master Network Server to be statically or dynamically assigned for
every subnet (even within the same network), which Manager/One users are
redirected to if they try to log into a non-Master Network Server.
The Master Network Server supports SNTP (Simple Network Time Protocol)
and is responsible for sending out the correct clock for the subnet as part of
the CIMS protocol. In this way, only the Master Network Server need derive
the clock from an independent stratum 1 or 2 clock source. If the Master
Network Server fails, your Access/One Network quickly detects the failure, at
which point the network server with the next lowest IP address assumes the
role of master. In this case, when the failed Master Network Server comes
back online, it immediately re-establishes its role as master.
Choose whether you want the system to obtain the Master Network Server IP
address automatically (default), or use a pre-configured static IP address. If
you choose the latter option, enter a valid IP address in the appropriate field.
◗ Static Network Servers
Static network servers are added to bond subnets together, allowing you to
configure and manage multiple subnets. You do this by starting with one
subnet and adding the Master Network Server IP addresses of other subnets to
tie them together.
Enter the IP address of a network server module on another subnet (the
default subnet mask is 255.255.255.255), then click on the Update button. to
add the server to a list. If you enter multiple static network servers, you must
click on the Update button after each entry for your changes to take effect.
To delete a static network server’s IP address, simply click on the X icon
alongside the address.
