MGX 8230 MGX to BPX Feeder

Maintenance Port

Through the maintenance port (sometimes called the modem port), you can connect either a single workstation running an IP-based application or a terminal server that supports multiple workstations. The workstation must support SLIP. Typically, use of this port includes a modem because the shelf resides at a remote location. The typical applications are software and firmware download or tasks that require low-level access.

Other Ports

Other ports exist on the PXM1-UI and PXM-UI-S3. These ports support external clock sources and external, third-party audio or visual alarm systems. For information on the function of other ports, see Chapter 6, “Card and Service Configuration”

IP-Based Applications

The maintenance port and Ethernet port support IP-based applications. Through these ports, the following applications run:

•Telnet supports CLI command execution from any IP-based application window as well as a window in the Cisco WAN Manager application.

•TFTP lets you download firmware and upload and download configuration information.

•SNMP supports equipment management through the CiscoView application and connection management through the Cisco WAN Manager application.

MGX 8230 MGX to BPX Feeder

As a BPX feeder, the MGX 8230 concentrates user ATM, Frame Relay, and circuit emulation traffic and feeds it to a BPX 8000 series switch over an OC-3 or OC-12 feeder trunk. The BPX series switch performs the switching and routing of the MGX 8230 user-connections through an MGX and BPX network. Figure 5-1is a simplified diagram of the MGX 8230 MGX feeder application.

Initial MGX 8230 Bring-Up

This section describes how to start up the MGX 8230 for the first time. It begins with an MGX 8230 PXM that has only boot-mode firmware. The descriptions tell you how to:

1.Establish communication with the MGX 8230.

2.Configure one or more boot-level IP addresses to make the MGX 8230 available to the network.
