Command-Line Interface

For switches shipped or upgraded with the Cisco Catalyst 1900/2820 Enterprise Edition

Software, you can use the command-line interface (CLI) to access the conﬁguration options

and perform the same conﬁguration and monitoring tasks available through the

Catalyst 1900 Switch Manager and management console. You can also perform privileged

conﬁguration and monitoring tasks available only through the CLI and SNMP.

For complete information about the CLI, refer to the online-only Catalyst 1900 Series and

Catalyst 2820 Series Command Reference.

Simple Network Management Protocol

You can conﬁgure and monitor the switch by accessing the Management Information Base

(MIB) variables through Simple Network Management Protocol (SNMP), an

application-layer protocol designed to facilitate the exchange of management information

between network devices. The switch supports a comprehensive set of MIB objects,

including four Remote Monitoring (RMON) groups.

The SNMP system consists of three parts: SNMP manager, SNMP agent, and the MIB ﬁles.

SNMP places all operations in a get-request, get-next-request, and set-request format. For

example, an SNMP manager can get a value from an SNMP agent or store a value into that

SNMP agent. The SNMP manager can be part of a network management system (NMS),

and the SNMP agent can reside on a networking device such as a switch. You can compile

the switch MIB ﬁles with your network management software. The SNMP agent can

respond to MIB-related queries being sent by the NMS.

An example of an NMS is the CiscoWorks network management software. CiscoWorks

uses the switch MIB variables to set device variables and to poll devices on the network for

speciﬁc information. The results of a poll can be displayed as a graph and analyzed in order

to troubleshoot internetworking problems, increase network performance, verify the

conﬁguration of devices, monitor trafﬁc loads, and more.
