NIC Naming Schemes
A single I/O Port destination can be configured with a variety of model and logpath combinations. For instance, once you set the parameters for m1 and l1, you can assign the model and logpath to more than one I/O port destination such as d1prn, d2prn, and d8prn. You may now use the same set of model and logpath parameters more than once without having to redefine those parameters each time for another I/O Port destination.
Periodic Ping
This feature when enabled executes background ping from the print server to its default gateway. The operation is executed on every user defined period. This mechanism has no TCP traffic from the print server to anything on the network to keep route information alive. Since every member in the VLAN is subject to aging from bridging cache, a switch or bridge in between may be forgotten in the table at which port the printer was connected. If one ping is run from printer server to its default gateway through the switch, the switch learns again and the route is seen. The problem will not be seen with TCP since the ACKs keep the bridge relearning in a switch. Periodically send ICMP Echo Request between a print server and its gateway that is typically situated in the same VLAN and connected with the same switch or bridge.
The printer server allows a periodic group of ping packets [1 – 5] to be issued by a set time [1– 5] minutes, to the gateway value the NIC has from its routing table. This feature can be enabled or disabled. The default is disable.
