Establishing SNMP community strings

Syntax: show snmp server
NOTE
If display of the strings is encrypted, the strings are not displayed. Encryption is enabled by default.
Using the user-based security modelSNMP version 3 (RFC 2570 through
2575) introduces a User-Based Security model (RFC 2574) for authentication and privacy services.
SNMP version 1 and version 2 use community strings to authenticate SNMP access to
management modules. This method can still be used for authentication. In SNMP version 3, the
User-Based Security model of SNMP can be used to secure against the following threats:
• Modification of information
• Masquerading the identity of an authorized entity
• Message stream modification
• Disclosure of information
SNMP version 3 also supports View-Based Access Control Mechanism (RFC 2575) to control
access at the PDU level. It defines mechanisms for determining whether or not access to a
managed object in a local MIB by a remote principal should be allowed. (refer to “SNMP v3
Configuration examples” on page 1023.)
Configuring your NMS
In order to use the SNMP version 3 features.
1. Make sure that your Network Manager System (NMS) supports SNMP version 3.
2. Configure your NMS agent with the necessary users.
3. Configure the SNMP version 3 features in devices.
