SYNOPSISsnmpstatus [COMMON OPTIONS] [-Cf] AGENT
DESCRIPTIONsnmpstatus 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)
snmpstatus -c public -v 1 netdev-kbox.cc.cmu.edu
will produce output similar to the following:
[18.104.22.168]=>[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.
- COMMON OPTIONS
- Please see snmpcmd(1) for a list of possible values for COMMON OPTIONS as well as their descriptions.
- 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.
