snmptable

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

atIfIndex atPhysAddress atNetAddress
1 8:0:20:20:0:ab 130.225.243.33

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

SNMP table: at.atTable

$ snmptable localhost -Cl -CB -Ci -OX -Cb -Cc 16 -Cw 64 ifTable

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.
