Configuring SNMP communities

Note: You can create or update SNMP community strings only if you open the switch using a read-write access community string (by default, the string is "private" for read-write). For example, to open a switch using a read-write access community string, choose Device > Open. Enter "private" for the Read Community and "private" for the Write Community. The string private appears as *******. If you do not open a device using a read-write access community string, you can only view the SNMP Community tab, and CommunityString is displayed as **** for the entry (for example, private) with read-write access.

You can create up to four SNMP community strings¹ for the SNMP management host, and specify the strings as having read-only or read-write privileges.

• read-only--allows read-only access to the switch's SNMP agent. The default read-only community string is public.
• read-write--allows read and write access to the switch's SNMP agent. The default read-write community string is private.

To configure SNMP community strings:

1. From the Device Manager menu bar, choose Edit > Security.

The Security dialog box opens with the SNMP Community tab displayed.

2. Click Insert.

The Security, Insert SNMP Community dialog box opens.

3. In the Security, Insert SNMP Community dialog box, enter a community string name (up to 32 alphanumeric characters).
4. In the CommunityLevel field, select the appropriate read/write privilege.
5. Click Insert.

The new community string appears in the Security dialog box--SNMP Community tab.

• Configuring management station IP addresses
• Managing the chassis

A community sting is an alphanumeric string of up to 32 characters used to authenticate user access to the switch's SNMP agent.
