na_snmpd - snmp agent daemon
The filer supports an SNMP version 1 (RFC 1157) compatible
agent that provides support for both the MIB-II (RFC 1213)
management information base for TCP/IP based internets as
well as a Data ONTAP Custom MIB.
A number of user configurable options for the SNMP agent
can be set and queried from the console using the snmp
command (see na_snmp(1)).
Due to weak authentication in SNMP version 1, SetRequest
commands that allow the remote setting of configuration
variables have been disabled.
Access for snmp can be restricted by the options
snmp.access command. Please see na_protocolaccess(8) for
details.
- MIB-II
-
Under MIB-II, information is accessible for the system,
interfaces, at, ip, icmp, tcp, udp and snmp MIBII
groups. The transmission and egp groups are not
supported.
The coldStart, linkDown, linkUp and authenticationFailure
traps are implemented. Traps are configured
using the snmp command.

DATA ONTAP CUSTOM MIB
-
The Data ONTAP Custom MIB provides a means to obtain
detailed information about many aspects of filer
operation via SNMP. The Custom MIB can be obtained
from Network Appliance's FTP site at
ftp://ftp.netapp.com/pub/netapp/mib/netapp.mib, or by
requesting the MIB on a floppy disk from Network
Appliance Technical Support.
The following is a summary of the top-level groups in
the Custom MIB and the information they contain:
product
Product-level information such as the software
version string and system ID.
sysStat
System-level statistics such as CPU uptime,
idle time and aggregate kilobytes received
and transmitted on all network interfaces.
nfs
Statistics like those displayed by the nfsstat
command (see na_nfsstat(1)), including
statistics for each client if per-client NFS
statistics have been enabled using the
nfs.per_client_stats.enable option (see
na_options(1)). The per-client NFS statistics
are indexed by client IP addresses.
quota
Information related to disk quotas, including
the output of the quota report command (see
na_quota(1)). To access quota information,
quotas must be turned on.
filesys
Information related to the file system,
including the equivalent of the maxfiles and
df commands, and some of the information from
the snap list command (see na_df(1), na_maxfiles(1),
na_snap(1)).
raid
Information on RAID equivalent to the output
of the sysconfig -r command (see na_sysconfig(1)).
In takeover mode, SNMP agents can continue to access the
MIBs on both filers in a cluster. However, the counters
reported by SNMP are combined counters from both filers.
For example, in takeover mode, the SNMP agent can report
the number of packets sent or received by both filers, but
you cannot determine from the number how many packets are
sent or received on each filer.
You can have an application on the network management station
set an alarm when a filer has been taken over. The
SNMP variable to check is the netapp.netapp1.sysStat.cf.cfSettings
variable. If this variable is set to
thisNodeDead, the filer has been taken over.
