LMI Behavior (Cont'd)
Port-1_Follows_Net1-FR1 – Brings LMI down on Port-1 when LMI on the network
interface goes down, disabling Port 1 and deasserting its control leads. When LMI on the
network interface comes back up, Port-1 is reenabled and its control leads are reasserted.
The LMI state on Port-1 has no effect on the LMI state on the network interface. That is,
Port-1’s LMI follows the network interface’s LMI. This setting is useful if the router
connected to Port-1 is used to initiate recovery when network failures are detected.
Port-2_Follows_Net1-FR1 – Reacts like the Port-1_Follows_Net1-FR1 selection, but for
Port-2 instead.
All_Ports_Follow_Net1-FR1 – Brings LMI down on all user data ports when LMI on the
network interface goes down, disabling all ports and deasserting their control leads.
Allows LMI to come back up and reenables the ports when LMI comes up on the network.
That is, LMI on each port follows the network interface’s LMI. The state of LMI on the port
will not affect the state of LMI on the network interface.
Port-1_Codependent_with_Net1-FR1 – Brings LMI down on the network interface when
LMI on Port-1 goes down (or LMI down on Port-1 when LMI on the network interface goes
down), and allows LMI to come back up when LMI comes back on the other interface.
That is, the LMI state for one interface is dependent on the other. Use this setting when
backup is through the router instead of the unit. It is
not recommended since it makes fault
isolation more difficult.
Port-2_Codependent_with_Net1-FR1 – Reacts like the
Port-1_Codependent_with_Net1-FR1 selection, but for Port-2 instead. The state of LMI on
the network interface will not affect the state of LMI on Port-1.
Traffic Policing
Possible Settings: Enable, Disable
Default Setting: Disable
Determines whether or not CIR (Committed Information Rate) and EIR (Excess
Information Rate) will be enforced by the unit on frames being sent on network frame relay
links.
Enable – CIR and EIR are enforced.
T Frames that exceed CIR will be marked Discard Eligible (DE). These frames are
counted in the
Above CIR but within EIR category until this category is full.
Once full, additional frames are counted as being in the Within CIR category.
T Frames in excess of EIR will be discarded.
Disable – CIR and EIR are not enforced.
LMI Error Event (N2)
Possible Settings: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Default Setting: 3
Configures the LMI-defined N2 parameter, which sets the number of errors that can occur
on the LMI link before an error is reported. Applies to both the user and network sides of a
UNI.
1 – 10 – Specifies the maximum number of errors.
