Configuring Physical Ports 6-3Database and System Memory ValuesTwo sets of values exist for Port parameters: Database values exist in the software, andare recorded as System Memory values when the node is booted. If the port type is thesame in both sets of values, both sets will be displayed.Any change you make will be recorded as a Database value, and will be copied to theSystem Memory side only if you press [F7]. Note that changes will not be actually besaved to the database until you press [F3] to exit the record.Pressing [F7] will display: On-line changes disable link, are you sure you want to? Ifyou press [Y], the link will be disabled, parameters copied, and the link re-enabled. Ifyou press [N], you will be prompted: Do you want to change port parameters partiallywithout disable? Pressing [Y] will propagate any changes to those parameters that donot require disabling the link. Pressing [N] will return you to the next higher screen.Configuring a Physical PortBefore configuring a physical port, make sure that the following have been properlyconfigured:l Node parameters. See Chapter 4. This is general configuration that must be doneno matter which protocols will be run in the node.l RLP that contains the port, plus Line Interface Card that supports the port. SeeChapter 5.l Protocol(s) that will be transmitted over the physical port and any logical portson the physical port. See Chapter 5.Once these necessary records have been configured, press [A] (Configuration), then [C](Configure Ports), then [A] from the Main Menu. As prompted, enter:l RLP containing the port: 0–2. (The default is 0.) (See Figure 6-1.)l Port (see Figure 6-2): 0–7. (The default is 0.)The display for an existing record will show the configured parameter values, whilethe display for a new record will show values stored in a default database record. Thefollowing figure is an example of a new record.
