Introduction 78
Model 3086FR ATM IAD User Guide 7 • Local Management Interface
Introduction
The Frame Relay Local Management Interface (LMI) is a mechanism that enables two separate frame relay sys-
tems to communicate the status of the interface. The LMI interface supports dynamic updates on the status of
the DLCI connections and the congestion state of the network. The Model 3086FR fully supports the LMI
versions listed in
table 4.
LMI Configuration Options
LMI is configurable via the CLI or web interface.
Note
Although the Model 3086FR supports LMI implementations for network,
user, and both, configuration options are limited to network for FRF.8 appli
-
cations, and both for FRF.5 applications.
managementType: (Default Value: no_maintenance)
the managementType variable defines the LMI protocol that will be used. The following options are available.
• no_maintenance: No maintenance interface will be used for this frame relay connection.
• ITU_Network: The ITU Q.933 protocol will be used. The unit will operate as the Network side of the
connection
• ITU_User: The ITU Q.933 protocol will be used. The unit will operate as the User side of the connection
• ITU_Both: The ITU Q.933 protocol will be used. The unit will operate as both the Network and User side
of the connection.
• ANSI_Network: The ANSI T1.617 protocol will be used. The unit will operate as the Network side of the
connection
• ANSI_User: The ANSI T1.617 protocol will be used. The unit will operate as the User side of the connection
