snmpConfig

Manages the SNMP agent configuration.

SYNOPSIS

snmpConfig --set mibCapability
[-mib_name mib_name [-bitmask bit_mask]]

snmpConfig --enable | --disable mibCapability
-mib_name mib_name [-trap_name trap_name]

snmpConfig --enable | --disable snmpv1

snmpConfig --help

DESCRIPTION

Use this command to manage the configuration of the SNMP agent in the switch. The configuration
includes SNMPv1 and SNMPv3 configuration, access control list (ACL), MIB capability, system group,
and security level settings. The command supports set, reset to default, and display operations.

The SNMP Agent configuration interface is interactive for all parameters except mibCapability, which
can be configured both interactively and with command line options on platforms running Fabric OS
v6.4.0 and later. The enhanced command line interface supports enabling or disabling a single MIB or all
MIBs, configuring a single trap only, and managing traps in excess of 32.

The SNMPv3 configuration supports sending inform requests as an alternative to trap requests. Traps
are unreliable because the receiver does not send any acknowledgment when it receives a trap. The
sender cannot determine if the trap was received. However, an SNMP manager that receives an inform
request acknowledges the message with an SNMP response protocol data unit (PDU). If the manager
does not receive an inform request, it does not send a response. If the sender never receives a
response, the inform request can be sent again. For this reason, informs are more likely to reach their
intended destination.

All values successfully changed by this command take effect immediately and are persistent across
power cycles and reboots.

In Fabric OS v7.0.0 and later, you can use this command to block or unblock access to SNMPv1/v2c. If
SNMPv1/v2c access is blocked, all requests for v1/v2c version will be dropped by the switch, and
SNMPv1 traps will be blocked from being sent, even if trap destinations are present. Enforcement of this
feature takes precedence over other SNMP security related features, such as accessControl or seclevel.

NOTES

The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for
details.

Informs are not supported for IPv6 addresses.
