createSec2Group MODEL SECURITYNAME GROUPNAME¶

Create an entry in the SNMPv3 security name to group table. This table allows a single access control entry to be applied to a number of users (or 'principals'), and is indexed by the security model and security name values.

MODEL

An integer representing the security model, taking one of the following values:
1 - reserved for SNMPv1
2 - reserved for SNMPv2c
3 - User-based Security Model (USM)

SECURITYNAME

A string representing the security name for a principal (represented in a security-model-independent format). For USM-based requests, the security name is the same as the username.

GROUPNAME

A string identifying the group that this entry (i.e. security name/model pair) should belong to. This group name will then be referenced in the access table (see createAccess below).

deleteSec2Group MODEL SECURITYNAME¶

Delete an entry from the SNMPv3 security name to group table, thus removing access control settings for the given principal. The entry to be removed is indexed by the MODEL and SECURITYNAME values, which should match those used in the corresponding createSec2Group command (or equivalent).

createView [-Ce] NAME SUBTREE MASK¶

Create an entry in the SNMPv3 MIB view table. A MIB view consists of a family of view subtrees which may be individually included in or (occasionally) excluded from the view. Each view subtree is defined by a combination of an OID subtree together with a bit string mask. The view table is indexed by the view name and subtree OID values.

[-Ce]

An optional flag to indicate that this view subtree should be excluded from the named view. If not specified, the default is to include the subtree in the view. When constructing a view from a mixture of included and excluded subtrees, the excluded subtrees should be defined first - particularly if the named view is already referenced in one or more access entries.

NAME

A string identifying a particular MIB view, of which this OID subtree/mask forms part (possibly the only part).

SUBTREE

The OID defining the root of the subtree to add to (or exclude from) the named view.

MASK

A bit mask indicating which sub-identifiers of the associated subtree OID should be regarded as significant.

deleteView NAME SUBTREE¶

Delete an entry from the SNMPv3 view table, thus removing the subtree from the given MIB view. Removing the final (or only) subtree will result in the deletion of the view. The entry to be removed is indexed by the NAME and SUBTREE values, which should match those used in the corresponding createView command (or equivalent).

When removing subtrees from a mixed view (i.e. containing both included and excluded subtrees), the included subtrees should be removed first.

createAccess GROUPNAME [CONTEXTPREFIX] MODEL LEVEL CONTEXTMATCH READVIEW WRITEVIEW NOTIFYVIEW¶

Create an entry in the SNMPv3 access table, thus allowing a certain level of access to particular MIB views for the principals in the specified group (given suitable security model and levels in the request). The access table is indexed by the group name, context prefix, security model and security level values.

GROUPNAME

The name of the group that this access entry applies to (as set up by a createSec2Group command, or equivalent)

CONTEXTPREFIX

A string representing a context name (or collection of context names) which this access entry applies to. The interpretation of this string depends on the value of the CONTEXTMATCH field (see below).

If omitted, this will default to the null context "".

MODEL

An integer representing the security model, taking one of the following values:
1 - reserved for SNMPv1
2 - reserved for SNMPv2c
3 - User-based Security Model (USM)

LEVEL

An integer representing the minimal security level, taking one of the following values:
1 - noAuthNoPriv
2 - authNoPriv
3 - authPriv

This access entry will be applied to requests of this level or higher (where authPriv is higher than authNoPriv which is in turn higher than noAuthNoPriv).

CONTEXTMATCH

Indicates how to interpret the CONTEXTPREFIX value. If this field has the value '1' (representing 'exact') then the context name of a request must match the CONTEXTPREFIX value exactly for this access entry to be applicable to that request.

If this field has the value '2' (representing 'prefix') then the initial substring of the context name of a request must match the CONTEXTPREFIX value for this access entry to be applicable to that request. This provides a simple form of wildcarding.

READVIEW

The name of the MIB view (as set up by createView or equivalent) defining the MIB objects for which this request may request the current values.

If there is no view with this name, then read access is not granted.

WRITEVIEW

The name of the MIB view (as set up by createView or equivalent) defining the MIB objects for which this request may potentially SET new values.

If there is no view with this name, then read access is not granted.

NOTIFYVIEW

The name of the MIB view (as set up by createView or equivalent) defining the MIB objects which may be included in notification request.

Note that this aspect of access control is not currently supported.

deleteAccess GROUPNAME [CONTEXTPREFIX] MODEL LEVEL¶

Delete an entry from the SNMPv3 access table, thus removing the specified access control settings. The entry to be removed is indexed by the group name, context prefix, security model and security level values, which should match those used in the corresponding createAccess command (or equivalent).

createAuth GROUPNAME [CONTEXTPREFIX] MODEL LEVEL AUTHTYPE CONTEXTMATCH VIEW¶

Create an entry in the Net-SNMP extension to the standard access table, thus allowing a certain type of access to the MIB view for the principals in the specified group. The interpretation of GROUPNAME, CONTEXTPREFIX, MODEL, LEVEL and CONTEXTMATCH are the same as for the createAccess directive. The extension access table is indexed by the group name, context prefix, security model, security level and authtype values.

AUTHTYPE

The style of access that this entry should be applied to. See snmpd.conf(5) and snmptrapd.conf(5) for details of valid tokens.

VIEW

The name of the MIB view (as set up by createView or equivalent) defining the MIB objects for which this style of access is authorized.

deleteAuth GROUPNAME [CONTEXTPREFIX] MODEL LEVEL AUTHTYPE¶

Delete an entry from the extension access table, thus removing the specified access control settings. The entry to be removed is indexed by the group name, context prefix, security model, security level and authtype values, which should match those used in the corresponding createAuth command (or equivalent).

Note that snmpget REQUIRES an argument specifying the agent to query as described in the .I snmpcmd(1) manual page.
