14.3.8 Maintenance
The Access Bank II SNMP provides maintenance functions for the following SNMPv2 operations.
• Loopback operations: T1 remote line and payload. Loopback operations verify and seg-
ment operating network interface circuits.
• Fault isolation: BERT QRSS test patterns in conjunction with loopback operations.
The user may also employ standard Internet PING function tests to check the connectivity at the IP
layer.
All features of the Access Bank II SNMP are manageable through the Command Line Interface (CLI)
using a VT-100 terminal via the RS-232 port, or using a Telnet terminal session over the Ethernet
port.
All product configurations specified in RFC1406 and RFC1659 are controllable through SNMP Net-
work Management Stations, with the following exceptions: DSX-1 metallic loopback, bit error pat-
tern generation and detection, and advanced redundancy options. In future software releases, it will
be possible to add private enterprise objects that represent information specific to these Carrier
Access Corporation product features.
14.4 Command Line Interface (CLI)
The Command Line Interface gives the user the most complete management capability. The Com-
mand Line Interface is accessible via the 10BaseT Ethernet connection using the Telnet protocol or
via the RS-232 management port.
14.4.1 Local and Remote CLI Management
The Access Bank II SNMP provides CLI management through its RS-232 and Ethernet 10Base-T
ports, as shown in Figure 14-3 and Figure 14-4.
For RS-232 CLI management, a cable is connected from the RS-232 port on the Access Bank II
SNMP to a PC or laptop computer. You can use a VT-100 terminal emulation program such as
Microsoft Hyper Terminal
® . CLI can also be used from a remote site by connecting the RS-232 port
to a modem and telephone line.
For Telnet CLI management, you can use a Telnet TCP/IP communications program to access CLI
through the Ethernet management port. Remote Telnet CLI operation is available using Telnet over
Ethernet or using inband T1 via the V.35 data port.
