Configuring the Overall System

The System menu options are described in the following sections:

Configuring Frame Relay and LMI for the CSU/DSU

Configuring Class of Service Definitions

Code Point Definitions

Service Level Verification Options (Advanced SLM Feature Set)

￿Configuring General System Options

Configuring Frame Relay and LMI for the CSU/DSU

Select Frame Relay and LMI from the System menu to display or change the Frame Relay and LMI (Local Management Interface) options for the entire system (see Table 4-2, CSU/DSU Frame Relay and LMI Options). The Frame Relay and LMI options do not apply to the router.

LMI Behavior (9720)

Possible Settings: Independent, Net1-FR1_Follows_Port-1,

Port-1_Follows Net1-FR1, Port-1 Codependent_with_Net1-FR1

Default Setting: Port-1_Codependent_with_Net1-FR1

Allows the state of the LMI to be passed from one interface to another.

Independent – The LMI state for each interface is handled separately, and is not affected by the LMI state of the other interface.

Net1-FR1_Follows_Port-1– The LMI state for the Net1-FR1 interface follows the state of the LMI of the Port 1 interface. If the LMI is down on the Port 1 interface, the system brings down the LMI on the Net1-FR1 interface, and when the LMI is up on Port 1, the system brings up the LMI on the Net1-FR1 Interface. This setting is useful at a central site when the remote site router on the other end of the PVC connection can initiate recovery via a redundant central site when there is a catastrophic central site LAN or router failure. Not recommended for NSPs.

Port-1_Follows_Net1-FR1– Brings down LMI on Port-1 when there is a physical failure on the network interface. When the alarm on the network interface is cleared, Port-1 is re-enabled and its control leads are reasserted. This setting is useful if the router connected to Port-1 is used to initiate recovery when network failures are detected.

Port-1_Codependent_with_Net1-FR1– The LMI state for Port 1 and the Net1-FR1 interface are dependent on each other. If the LMI is down on either interface, the system will bring the LMI down on the other interface. When the LMI is up on either interface, the system will bring the LMI up on the other interface.
