Below is a description of the fields on this screen:
Port
Selects the port to be configured.
Mode
Configures the port as physical DCE (supplies clock), DTE (receives clock), or Disable
(disables the port altogether). Disable is recommended if the port will not be in use.
Link Type
Specifies the logical interface for the Magnum Router port. Select from the options in the
list box. (Link Types are illustrated in Chapter 8). Below is a description of each link
type.
FR_PUBLIC
Is used when connecting a Magnum WAN port to a public Frame Relay network.
FR_DEDICATED
Is used when connecting a Magnum Router to a Marathon or another type of
Frame Relay Access Device (bridge, Router, FRAD). The Magnum WAN port
functions as a frame relay network port when using this setting.
DEDICATED-MASTER
Use when connecting Magnum Router’s over dedicated digital data circuits (such
as 56K point to point leased lines or T1/E1 or fractional T1/E1 dedicated leased
lines). Selecting the DEDICATED-MASTER causes the Magnum Router WAN
port to function as a Frame Relay Network Port (supplying LMI and DLCI
information to the remote site(s)).
DEDICATED-SLAVE
Use when connecting Magnum Router’s over dedicated digital data circuits (such
as 56K point-to-point leased lines or T1/E1 or fractional T1/E1 dedicated leased
lines). Selecting the DEDICATED-SLAVE causes the Magnum Router WAN port
to function as a Frame Relay User Port (accepting LMI and DLCI information
from the Magnum Router Master unit).
Link Management
Defines the Frame Relay Link Management protocol, either ANSI/Annex D or LMI or
Annex A.
Link management protocol is used in all public Frame Relay applications. The Magnum
Router WAN port(s) must match the lmi type being provided by the carrier. It is
recommended that you request ANSI /Annex_ D for all your frame relay connections.
If installing Magnum Routers on a dedicated (or DDS) circuit, it is important to note tha
t
one of the Magnum Routers needs to be set as DEDICATED_MASTER and the other as
DEDICATED_SLAVE in order to create a private frame-relay network.
