Defining SNMP views

Displaying user information

To display the definition of an SNMP user account, enter a command such as the following.
BigIron RX(config)# show snmp user
username = bob
acl id = 2
group = admin
security model = v3
group acl id = 0
authtype = md5
authkey = 3aca18d90b8d172760e2dd2e8f59b7fe
privtype = des,
engine ID= 800007c70300e052ab0000
Syntax: show snmp user

Interpreting varbinds in report packets

If an SNMP version 3 request packet is to be rejected by an SNMP agent, the agent sends a report
packet that contains one or more varbinds. The varbinds contain additional information, showing
the cause of failures. An SNMP manager application decodes the description from the varbind.
The following table presents a list of varbinds supported by the SNMP agent.
Varbind object identifier
1. 3. 6. 1. 6. 3. 11. 2. 1. 3. 0
1. 3. 6. 1. 6. 3. 12. 1. 5. 0
1. 3. 6. 1. 6. 3. 15. 1. 1. 1. 0
1. 3. 6. 1. 6. 3. 15. 1. 1. 2. 0
1. 3. 6. 1. 6. 3. 15. 1. 1. 3. 0
1. 3. 6. 1. 6. 3. 15. 1. 1. 4. 0
1. 3. 6. 1. 6. 3. 15. 1. 1. 5. 0
1. 3. 6. 1. 6. 3. 15. 1. 1. 6. 0
Defining SNMP views
SNMP views are named groups of MIB objects that can be associated with user accounts to allow
limited access for viewing and modification of SNMP statistics and system configuration. SNMP
views can also be used with other commands that take SNMP views as an argument. SNMP views
reference MIB objects using object names, numbers, wildcards, or a combination of the three. The
numbers represent the hierarchical location of the object in the MIB tree. You can reference
individual objects in the MIB tree or a subset of objects from the MIB tree.
