CHAPTER 3: LOCAL MANAGEMENT

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.
