Management Interfaces
The Wide Bank 28 DS3 has four management interfaces (see Figure 8-1):
Command Line Interface (CLI). An ASCII language, communicated over an RS-232 data
port or via Ethernet through a Telnet session. The Command Line Interface is a scrolling
interface. It is operated only from a dumb terminal (VT100) or a terminal emulation program
such as ProComm or HyperTerminal.
SNMP Agent. Simple Network Management Protocol (SNMP), an industry standard
management interface, communicated through IP over a 10Base-T Ethernet data port. The
Wide Bank’s embedded SNMP Agent attaches to an Ethernet connection. It is operated by an
SNMP Manager application such as SunConnect SunNet Manager, HP OpenView, or Castle
Rock SNMPc, and the Carrier Access NetworkValet.
Transaction Language One (TL1). TL1 compliant automatic outbound alarming through
either a 25-pin RS-232 port or over TCP/IP. The Wide Bank also supports TL1 commands
over these same interfaces (see Chapter 9).
PPP over DS3. Point-to-Point Protocol (PPP) can be used to support TFTP, SNMP, Telnet,
Ping, and TL1 over the DS3 link between two Wide Banks using C-bit framing. Management
commands are sent through the Ethernet port of the local Wide Bank for routing over the DS3
C-bit data link to a remote Wide Bank. To use this mode, the local Wide Bank must be
configured with the IP PPP Address of the remote Wide Bank and the IP Route is set to
Ethernet. The remote Wide Bank’s IP Route is set to PPP.
Management interfaces access the same configuration and data structures for low-speed DS1 and
E1 and high-speed DS3 interfaces. CLI has more maintenance and monitoring features than the
SNMP Agent. In other words, CLI manages a superset of the SNMP Agent. However, SNMP can
monitor status (traps), which CLI cannot.
