snmpConfig
When new passwords are entered for any user entry, a new authKey and privKey are generated.
The new passwords must be updated on the client (e.g., MIB browser) as well. AuthKey and privKey
can also be updated with the delta key mechanism provided by the SNMPv3 protocol.
The system prompts for password confirmation if a protocol other than NoAuth/NoPriv is selected.
Protocol passwords must be between 1 and 20 characters.
In order for an SNMP management station to receive SNMPv3 traps generated by the agent, the
administrator must configure a trap recipient value to correspond to the IP address of the
management station. In addition, the trap recipient must pass the ACL check as described in the
Access Control section. The trap recipient must be associated with one of the six users of SNMPv3
and trap severity level. The factory default value for the SNMPv3 trap recipient of each user is
0.0.0.0.
Access Control Configuration Parameters
The ACL check is as follows: there are six ACLs to restrict SNMP get, set, and trap operations to
hosts under an host-subnet-area. The host-subnet-area is defined by comparing nonzero IP octets.
For example, an ACL of 192.168.64.0 enables access by any hosts that start with the specified
octets. The connecting host is enabled to set each host-subnet-area to be read-write or read-only.
The closest match out of six entries is given access. The ACL check is turned off when all six entries
contain 0.0.0.0. The default values of all six entries are 0.0.0.0. For IPv6 subnets, the format is
specified by an IPv6 address followed by the number of fixed bits in the address.
MIB Capability Configuration Parameters
The mibCapability option turns certain MIBS and associated SNMP traps on or off. If a specific MIB
is disabled, the corresponding traps also are disabled. If any trap group is disabled, the
corresponding individual traps are also disabled. Use the --show mibCapability option to display
the traps configurable under each MIB. For more information, refer to the Fabric OS MIB
Reference.
The following MIB configuration options are supported:
--set mibCapability
884
Configures MIBs interactively. When used without a MIB name, this command
displays a menu with supported MIBs and associated traps, and for each MIB
or trap, you are prompted to confirm or change the default by specifying yes
or no. Specifying yes means you can access the MIB variables with an SNMP
manager.
For two traps under the SW-TRAP category, the swEventTrap and the
swFabricWatchTrap, this command provides the option to specify a severity
levels to control the number of generated alerts. When a severity level is
configured, traps below the specified severity level specified are not sent.
Refer to the example section for an illustration. Specify one of the following
values:
0 None (default)
1 Critical
2 Error
3 Warning
4 Informational
