b) You may add a new entry in the LAN-to-LAN or the Shared ISP, through

the Web Configurator, based on your needs.

The Local Management Interface (LMI) is a set of enhancements to the

basic Frame Relay specification. It is supported by the RAS 1500 and set

ON to ANSI T1.617 Annex –D by default.

However, make sure that your Frame-Relay service provider supports this

feature.

Some Frame-Relay providers require you to turn this feature OFF.

To disable LMI on your WAN port, use the following command at the CLI

prompt

: SET FRAME_RELAY ON INTERFACE RM0/WAN:1 MANAGEMENT_TYPE

NO_LMI

About LMI: LMI virtual circuit status messages provide communication

and synchronization between Frame Relay DTE and DCE devices. These

messages are used to periodically report on the status of PVCs,

preventing data from being sent into black holes (that is, over PVCs that

no longer exist).

The LMI global addressing extension gives Frame Relay DLCI values global

rather than local significance. DLCI values become DTE addresses that are

unique in the Frame Relay WAN.
