SNMP Configuration Overview
This section describes how to configure SNMP components that apply to SNMPv1,
SNMPv2c, and SNMPv3 on the 7705 SAR.
• Configuring SNMPv1 and SNMPv2c
• Configuring SNMPv3
Configuring SNMPv1 and SNMPv2c
The 7705 SAR router is based on SNMPv3. To use 7705 SAR routers with SNMPv1 and/or
SNMPv2c, SNMP community strings must be configured. Three predefined access methods
are available when SNMPv1 or SNMPv2c access is required. Each access method (
r, rw, or
rwa) is associated with an SNMPv3 access group that determines the access privileges and
the scope of managed objects available. The
community command is used to associate a
community string with a specific access method and the required SNMP version (SNMPv1
or SNMPv2c). The access methods are:
• read-only — grants read-only access to the entire management structure with the
exception of the security area
• read-write — grants read and write access to the entire management structure with
the exception of the security area
• read-write-all — grants read and write access to the entire management structure,
including security
If the predefined access groups do not meet your access requirements, then additional access
groups and views can be configured. The
usm-community command is used to associate an
access group with an SNMPv1 or SNMPv2c community string.
SNMP trap destinations are configured in the
config>log>snmp-trap-group context.
Configuring SNMPv3
The 7705 SAR implements SNMPv3. If security features other than the default views are
required, the following parameters must be configured:
•views
• access groups
•SNMP users
