LMI Behavior
Possible Settings: Independent,
Net1-FR1_Follows_Port-1,
Net1-FR1_Follows_Port-2,
Port-1_Follows_Net1-FR1,
Port-2_Follows_Net1-FR1,
All_Ports_Follow_Net1-FR1,
Port-1_Codependent_with_Net1-FR1,
Port-2_Codependent_with_Net1-FR1
Default Setting: Independent
Configures the device to allow the state of the LMI to be passed from one interface to
another, determining how the unit will handle a change in the LMI state. Sometimes
referred to as LMI pass-through.
NOTE: LMI Behavior cannot be changed while Auto Backup is enabled. A warning
message appears at the bottom of the screen if auto backup is enabled. First, disable
Auto Backup, and then change LMI Behavior.
Independent – Handles the LMI state of each interface separately so that the LMI state of
one interface has no effect on the LMI state of another interface. Provides LMI Spoofing.
This is the recommended setting when backup is configured, and for Network Service
Providers (NSPs).
Net1-FR1_Follows_Port-1 – Brings LMI down on the network interface when LMI on
Port-1 goes down, disabling the network interface and deasserting its control leads. When
LMI on Port-1 comes back up, the network interface is reenabled. The LMI state on the
network interface has no effect on the LMI state on Port-1. That is, the network interface’s
LMI follows Port-1’s LMI. Used at central sites, this setting is useful 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.
Net1-FR1_Follows_Port-2 – Reacts like the Net1-FR1_Follows_Port-1 selection, but for
Port-2 instead.
