3com 2200 User Manual

To manage the Switch 2200 from an external management application, you 
must configure SNMP community strings and set up trap reporting as 
described in this section.

You can manage the Switch 2200 using an SNMP-based external 
management application. This application (an SNMP manager) sends 
requests to the Switch 2200 system, where they are processed by the  
Switch SNMP agent. 

The SNMP agent provides access to the collection of information about the 
Switch 2200. In addition, a Switch 2200 SNMP agent sends traps to an 
SNMP manager to report significant events. Access to system information 
through SNMP is controlled by community strings. 

For more information about using SNMP to manage the Switch 2200, see 
Chapter 3: Management Access: Protocols in the SuperStack™ II Switch 2200 
Operation Guide.

You can display the current Switch 2200 SNMP configurations for the 
community strings.

To display SNMP settings, enter the following from the top level of the 
Administration Console:

The community string settings are displayed as shown here:

Read-only community is public

Read-write community is private

A community string is an octet string, included in each SNMP message, that 
controls access to system information. The Switch 2200 SNMP agents 
internally maintain two community strings that you can configure:

■

Read-only community strings with the default “public”

■

Read-write community strings with the default “private”

When an SNMP agent receives an SNMP request, the community string 
in the request is compared with the community strings configured for the 
agent. SNMP get, get-next, and set requests are valid if the community string
