Summary of User Interface Connections
• Configure and collect statistical information
A workstation is used to configure statistic types and collect the statistics files.
• Download firmware
A workstation is used to download firmware files onto the Cisco MGX 8220 shelf.

Physical Connections
The Cisco MGX 8220 shelf offers four physical access methods to perform these user interface
functions. The physical connection depends on the type of function to be performed.
• Serial line access through the RS-232 maintenance port of the ASC
• Serial line access through the RS-232 control port on the ASC using Serial Line IP SLIP
• Ethernet access through the AUI LAN port
• In-band access through eight dedicated virtual connections over the Cisco BPX network to the
BNM
The functions of these ports are described later in this chapter.
Protocols
The protocols that can be employed are
• CLI (maintenance port, control port, LAN port, and in-band)
Telnet is used to access the command-line interface (CLI) through the control, LAN, and in-band
ports. The maintenance port is used to connect a dumb terminal for direct entry of commands.
• TCP/IP TFTP (control port, LAN port, and in-band)
TFTP is used to transfer files between a workstation and the Cisco MGX 8220 shelf. This protocol
is used to configure and collect statistics and configuration files. It is also used to download
firmware to the Cisco MGX 8220 shelf.
• UDP/IP SNMP (control port, LAN port, and in-band)
SNMP is used to configure, monitor, and manage the Cisco MGX 8220 resources using SNMP get
and set commands. Cisco WAN Manager (CWM) or other registered SNMP Managers can be used
for SNMP functions.
