Security level Authentication

none

If the security model shows v1 or v2, then security level is blank. User names are not used to
authenticate users; community strings are used instead.

noauthNoPriv

Displays if the security model shows v3 and user authentication is by user name only.

authNoPriv

Displays if the security model shows v3 and user authentication is by user name and the MD5 or
SHA algorithm.

Displaying user information

To display the definition of an SNMP user account, enter a command such as the following.

device#show snmp user

username = bob

ACL id = 2

group = admin

security model = v3

group ACL id = 0

authtype = md5

authkey = 3aca18d90b8d172760e2dd2e8f59b7fe

privtype = des, privkey = 1088359afb3701730173a6332d406eec

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

Description

1. 3. 6. 1. 6. 3. 11. 2. 1. 3. 0 Unknown packet data unit.

1. 3. 6. 1. 6. 3. 12. 1. 5. 0

The value of the varbind shows the engine ID that needs to be used in the snmp-
server engineid command

1. 3. 6. 1. 6. 3. 15. 1. 1. 1. 0 Unsupported security level.

1. 3. 6. 1. 6. 3. 15. 1. 1. 2. 0 Not in time packet.

1. 3. 6. 1. 6. 3. 15. 1. 1. 3. 0 Unknown user name. This varbind may also be generated:

• If the configured ACL for this user filters out this packet.
• If the group associated with the user is unknown.

1. 3. 6. 1. 6. 3. 15. 1. 1. 4. 0 Unknown engine ID. The value of this varbind would be the correct authoritative

engineID that should be used.

1. 3. 6. 1. 6. 3. 15. 1. 1. 5. 0 Wrong digest.
