NAME
snmptable - retrieve an SNMP table and display it in tabular form
SYNOPSIS
snmptable [COMMON OPTIONS] [-Cb] [-CB] [-Ch] [-CH] [-Ci] [-Cf STRING] [-Cw WIDTH] AGENT TABLE-OID
DESCRIPTION
snmptable is an SNMP application that repeatedly uses the SNMP GETNEXT or GETBULK requests to query for information on a network entity. The parameter TABLE-OID must specify an SNMP table. 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 snmpcmd(1) for a full list of the possible formats for AGENT.
OPTIONS
COMMON OPTIONS
Please see snmpcmd(1) for a list of possible values for COMMON
OPTIONS as well as their descriptions.
-Cb Display only a brief heading. Any common prefix of the table
field names will be deleted.
-CB Do not use GETBULK requests to retrieve data, only GETNEXT.
-Cc CHARS
Print table in columns of CHARS characters width.
-Cf STRING
The string STRING is used to separate table columns. With this
option, each table entry will be printed in compact form, just
with the string given to separate the columns (useful if you
want to import it into a database). Otherwise it is printed in
nicely aligned columns.
-Ch Display only the column headings.
-CH Do not display the column headings.
-Ci This option prepends the index of the entry to all printed
lines.
-Cl Left justify the data in each column.
-Cr REPEATERS
For GETBULK requests, REPEATERS specifies the max-repeaters
value to use. For GETNEXT requests, REPEATERS specifies the
number of entries to retrieve at a time.
-Cw WIDTH
Specifies the width of the lines when the table is printed. If
the lines will be longer, the table will be printed in sections
of at most WIDTH characters. If WIDTH is less than the length
of the contents of a single column, then that single column
will still be printed.
Note that snmptable REQUIRES an argument specifying the agent to query
and exactly one OID argument, as described in the snmpcmd(1) manual
page. This OID must be that of a MIB table object.
EXAMPLES
$ snmptable -v 2c -c public localhost at.atTable
SNMP table: at.atTable RFC1213-MIB::atTable

$ snmptable -v 2c -c public -Cf + localhost at.atTable

BUGS
The test for TABLE-OID actually specifying a table is rather heuristic. Note also that the test requires the defining MIB file to be loaded.
