Usage guidelines
Use SNMP logging to record the SNMP operations performed on the SNMP agent or authentication
failures from the NMS to the agent for auditing NMS behaviors. The SNMP agent sends log data to
the information center. You can configure the information center to output the data to a destination as
needed.
Examples
# Enable logging SNMP Get operations.
<Sysname> system-view
[Sysname] snmp-agent log get-operation
# Enable logging SNMP Set operations.
<Sysname> system-view
[Sysname] snmp-agent log set-operation
# Enable logging SNMP authentication failures.
<Sysname> system-view
[Sysname] snmp-agent log authfail
snmp-agent mib-view
Use snmp-agent mib-view to create or update a MIB view.
Use
undo snmp-agent mib-view
to delete a MIB view.
Syntax
snmp-agent mib-view { excluded | included } view-name oid-tree [ mask
mask-value ]
undo snmp-agent mib-view view-name
Default
The system creates the ViewDefault view when the SNMP agent is enabled. In this default MIB view,
all MIB objects in the
iso
subtree but the snmpUsmMIB , snmpVacmMIB , and snmpModules.18
subtrees are accessible.
Views
System view
Predefined user roles
network-admin
Parameters
excluded : Denies access to any node in the specified MIB subtree.
included
: Permits access to all the nodes in the specified MIB subtree.
view-name
: Specifies a view name, a case-sensitive string of 1 to 32 characters.
oid-tree
: Specifies a MIB subtree by its root node's OID (for example, 1.3.6.1.2.1.1 ) or object
name (for example, system ). The
oid-tree
argument is a case-sensitive string of 1 to 255
characters. An OID is a dotted numeric string that uniquely identifies an object in the MIB tree.
mask mask-value
: Sets a MIB subtree mask, a case-insensitive hexadecimal string. Its length is
