Monitoring the Network with SNMP

This chapter explains monitoring the Catalyst 3000 from a Network Management System (NMS) using the CiscoView or any application that supports Simple Network Management Protocol (SNMP).

The following topics are covered in this chapter:

• SNMP Set-up
  
  
• IP Configuration
  
  
• SNMP Configuration
  
  

SNMP Set-up

Follow these steps to use in-band management:

Step 1 Attach the Catalyst 3000 to the console and start a console session as described in Chapter 6, "Connecting a Network Management Console."

Step 2 Complete the IP Configuration menu.

Step 3 Complete the SNMP Configuration menu and following sub-menus:

Community String menu.

Trap Receiver menu.

The following sections describe the SNMP set-up menus.

IP Configuration

The IP Configuration menu sets the IP address, gateway address, subnet mask, and IP state.

The IP Address and Default Gateway must be in the same subnet address class--that is, Class A, Class B, or Class C. The system prevents you from entering values from different classes. If you do inadvertently enter an incorrect value, enter 0.0.0.0 in every field, then re-enter the correct values.

Refer to Chapter 7, "Console Configuration," for a complete description on how to configure the IP Configuration menu.

SNMP Configuration

Use the SNMP Configuration Menu to configure specific attributes related to SNMP.

SNMP Configuration Screen

Send Authentication Traps

Indicates whether SNMP should issue an authentication trap to Trap Receivers whenever an unauthorized request is detected.

Default: Yes

Community String Menu

Changes the community string table. The community string is the name associated with the Catalyst 3000 and a set of SNMP Managers. Entries in the table are saved across resets and power cycles.

Trap Receiver Menu

Displays table of managers to which traps are sent. Entries in the table are saved across resets and power cycles.

Community String Menu

Use the Community String menu to configure the community string for the Catalyst 3000. The community string is the name associated with the Catalyst 3000 and a set of SNMP managers allowed to manage it with the specified privilege level.

---

Note Text within the community string is Upper/Lower case sensitive.
