 Level 2 (L2) = data
 Level 3 (L3) = config
 Level 4 (L4) = OEM
 Level 5 (L5) = Manufacturing (manuf)
Level 0 is the connectionless access level. Access over UDP will use this access
level. The L0 level provides access to the name query services. It is not an
authenticated level.
Level 1 is the default security level for CLI Sessions over TCP or the serial
interface.
CLI Sessions must execute the CLI command auth in order to authenticate the
CLI Sessions to another security level. The CLI command logout returns the
CLI Session back to security Level 1.
6.3 CLI Session Modes
The mode of the CLI Session governs the set of actions allowed in the CLI
session. The following are descriptions of each mode:
6.3.1 CLI Mode
CLI Mode is the command processing mode of the CLI Session. CLI Mode allows
users and OEM applications to simply execute module commands as described
in the section, “CLI Commands.”
A CLI Session may transition into CLI Mode automatically at startup of the CLI
Session (if so configured). See section “CLI Session Startup Modes” for details
on startup modes.
CLI Sessions may transition manually to CLI Mode from the other modes via the
use of the CLI escape processing feature in the CLI Server. See section “CLI
Server Escape Processing” for details.
6.3.2 PASS Mode
PASS Mode is an active data bridging mode of the CLI Server. PASS Mode
allows the user or OEM application to transfer data between a CLI Session on
the network interface and the CLI Session on the serial interface.
A CLI Session may transition to PASS Mode automatically at startup of the CLI
session (if so configured) or manually from the CLI Mode using the CLI
pass
command. See section “CLI Session Startup Modes” for details on startup
modes.
The transition from CLI Mode into PASS Mode differs depending on the attributes
of the CLI session. The following sections describe the two PASS Modes.
