Understanding Configuration Modes
The ADTRAN CLI has four configuration modes to organize the configuration commands – Global, Line,
Router, and Interface. Each configuration mode supports a set of commands specific to the configurable
parameters for the mode. For example, all frame relay configuration commands are accessible only
through the Interface Configuration Mode (for the virtual frame relay interface). The following table
contains a brief description of each level.
Table 2. Configuration Mode Descriptions
Mode Access by... Sample Prompt With this mode you
can...
Global
entering
config
while at the Enable
command security level prompt.
For example:
Router>enable
Router#
config term
Router(config)#
• set the system’s
Enable-level
password(s)
• configure the
system global IP
parameters
• configure the
SNMP parameters
• enter any of the
other configuration
modes
Line specifying a line (console or Telnet)
while at the Global Configuration Mode
prompt.
For example:
Router>enable
Router#config term
Router(config)#
line
console 0
Router(config-con0)#
• configure the
console terminal
settings (datarate,
login password,
etc.)
• create Telnet logins
and specify their
parameters (login
password, etc.)
Router
entering
router rip
router
or
router ospf
while at the Global
Configuration Mode prompt.
For example:
Router>enable
Router#config term
Router(config)#
router rip
Router(config-rip)#
• configure RIP or
OSPF parameters
• suppress route
updates
• redistribute
information from
outside routing
sources (protocols)
Interface specifying an interface (T1, Ethernet,
frame relay, ppp, etc.) while in the
Global Configuration Mode.
For example:
Router>enable
Router#config term
Router(config)#
int eth 0/1
Router(config-eth
0/1)#
(The above prompt is for the
Ethernet
LAN
interface located
on the rear panel of the unit.)
• configure
parameters for the
available LAN and
WAN interfaces
