CHAPTER 3: LOCAL MANAGEMENT
Page 16 BRIM-WT1 USER’S GUIDE
Max Xmit Unit
Displays the maximum packet size that can be transmitted on the selected
Interface. The default setting for this field is 1518. This is the maximum
packet size.
Line Coding
Displays the T1 Line Coding. This field displays INV-HDLC, JBZS,
B8ZS, or NOT USED. The default setting for this field is NOT USED.
Active Protocol
Displays the active Link Layer protocol. This field displays PPP (Point to
Point), FR (Frame Relay), or None.
PT#
Displays the Bridge Port that the BRIM-WT1 Local Management
automatically assigns to an Interface. If the active protocol for this
interface is PPP, Local Management assigns only one WAN bridge port. If
the active protocol is Frame Relay, Local Management may assign up to
31 WAN bridge ports.
Note: The MicroMMAC has 32 available bridge ports. Ethernet is the
first bridge port. The remaining 31 bridge ports are available for WAN
applications.
You can assign the 31 WAN bridge ports to the 24 interfaces in the
configuration that suits your needs. For example, you can assign all 31
WAN bridge ports to one interface. In this example, the remaining 23
interfaces would not have WAN bridge ports available.
The quantity of bridge ports for a Frame Relay network is determined by
the quantity of DLCIs (Data Link Connection Identifiers) assigned to that
Interface. This is determined either manually or by the LMI (Local
Management Interface).
IF#
Displays the Interface that is associated with the bridge port.
DLCI
Displays the Data Link Carrier Identifier. This field is specific to the
Frame Relay protocol. If the active protocol for this interface is PPP, then
PPP will appear in this field.
