SNMP Command Reference
version — specifies the SNMP version
usm-community
Syntax
usm-community community-string [hash | hash2] group group-name
no usm-community community-string [hash | hash2]
Context
config>system>security>snmp
Description
This command is used to associate a community string with an SNMPv3 access group and its view.
The access granted with a community string is restricted to the scope of the configured group.
The 7705 SAR OS implementation of SNMP uses SNMPv3. In order to implement SNMPv1 and
SNMPv2c configurations, several access groups are predefined. In order to implement SNMP with
security features (version 3), security models, security levels, and USM communities must be
explicitly configured. Optionally, additional views that specify more specific OIDs (MIB objects in the
subtree) can be configured.
The no form of this command removes a community string.
Default
n/a
Parameters
community-string — configures the SNMPv1/SNMPv2c community string to determine the
hash1 | hash2 — configures the hashing scheme for the community string

Syntax

Description
This command configures a view. Views control the accessibility of a MIB object within the
