8Preface

Each mode provides a speciﬁc set of commands. The command set of a higher-privilege mode is a superset of a lower-privilege mode. That is, all lower-privilege mode commands are accessible when using a higher-privilege mode.

The command modes are as follows:

•User EXEC mode

This is the initial mode of access. By default, the User Access Veriﬁcation Password for this mode is empty, and password checking is disabled. The password can be changed (and password checking enabled) by the system administrator in Global conﬁguration mode. Once the password is changed, it is activated immediately.

•Privileged EXEC mode

This mode is accessed from the User EXEC mode. When accessing this mode, you are prompted to provide a login name and password. The login name and password combination determines your access level in the Privileged EXEC mode and other higher modes.

•Global conﬁguration mode

This mode allows you to make changes to the running conﬁguration. If the conﬁguration is saved, these settings survive reboots of the switch.

•Interface conﬁguration mode

This mode allows you to modify either a logical interface, such as a VLAN, or a physical interface, such as a port/slot.

From either the Global conﬁguration mode or the Interface conﬁguration mode, all the conﬁguration parameters (both global and interface) can be saved to a ﬁle. The default name for the conﬁguration parameters ﬁle is conﬁg.cfg. Alternative ﬁlenames can also be used.

Table 1 "NNCLI command modes" (page 9) lists the NNCLI command modes, the prompts for each mode, the abbreviated name for each mode, and how to enter and exit each mode.

Prompts are expressed in this table using the format ERS-8300:5; however, prompts returned from your switch typically reﬂect the speciﬁc chassis you use. For example, if you use the 8310 chassis, the prompts use the format ERS-8310:5. Prompts can be customized, also, using the NNCLI command snmp-server name <prompt>.
