NAME¶

snmpstatus - retrieves a fixed set of management information from a network entity

SYNOPSIS¶

snmpstatus [COMMON OPTIONS] [-Cf] [-Sni] AGENT

DESCRIPTION¶

snmpstatus is an SNMP application that retrieves several important statistics from a network entity.

AGENT identifies a target SNMP agent, which is instrumented to monitor the given objects. At its simplest, the AGENT specification will consist of a hostname or an IPv4 address. In this situation, the command will attempt communication with the agent, using UDP/IPv4 to port 161 of the given target host.

See the snmpcmd(1) manual page for a full list of the possible formats for AGENT.

The information returned is:

The IP address of the entity.
A textual description of the entity (sysDescr.0)
The uptime of the entity's SNMP agent (sysUpTime.0)
The sum of received packets on all interfaces (ifInUCastPkts.* + ifInNUCastPkts.*)
The sum of transmitted packets on all interfaces (ifOutUCastPkts.* + ifOutNUCastPkts.*)
The number of IP input packets (ipInReceives.0)
The number of IP output packets (ipOutRequests.0)

For example:

snmpstatus -c public -v 1 netdev-kbox.cc.cmu.edu

will produce output similar to the following:

[128.2.56.220]=>[Kinetics FastPath2] Up: 1 day, 4:43:31
Interfaces: 1, Recv/Trans packets: 262874/39867 | IP: 31603/15805

snmpstatus also checks the operational status of all interfaces (ifOperStatus.*), and if it finds any that are not running, it will report in a manner similar to this:

2 interfaces are down!

If the network entity has an error processing the request packet, an error packet will be returned and a message will be shown, helping to pinpoint in what way the request was malformed. snmpstatus will attempt to reform its request to eliminate the malformed variable (unless the -Cf option is given, see below), but this variable will then be missing from the displayed data.

It is also possible to suppress parts of the default output by using the option -S (see below).

OPTIONS¶

COMMON OPTIONS

Please see snmpcmd(1) for a list of possible values for COMMON OPTIONS as well as their descriptions.

-Cf

By default, snmpstatus will try to fix errors returned by the agent and retry a request. In this situation, the command will display the data that it can. If the -Cf option is specified, then snmpstatus will not try to fix errors, and the error will cause the command to terminate.

-Sn

Do not retrieve and print network statistics such as packets sent and received and the number of network interfaces that are down.

-Si

Do not print the number of network interfaces that are down.
