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.
n this situation, the command will attempt communication with
the agent, using UDP/IPv4 to port 161 of the given target host.
manual page for a full list of the possible formats for AGENT.
The information returned is:
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:
[126.96.36.199]=>[Kinetics FastPath2] Up: 1 day, 4:43:31
Interfaces: 1, Recv/Trans packets: 262874/39867 |
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.
will attempt to reform its request to eliminate the malformed
variable (unless the
option is given, see below), but this variable will then be missing
from the displayed data.
