== MFD : ifTable testing ==

If you have not been compiling as you went along, try and compile
now.

<table><tr><td width=20></td><td><code>$</code></td><td bgcolor=CCCCCC>
<font color=blue>make -f ifTable_Makefile</font>
</td></tr>
</table>

After running make, you should have an executable named
''ifTable''.

=== Starting the agent ===

You can run the ''ifTable'' agent as a regular SNMP agent,
or as an AgentX sub-agent. The default is to run as a sub-agent. While
testing, the ''-f'' (do not fork into background) and ''-L'' (log
to stderr) options are recommended.

<table><tr>
<td width=20></td>
<td>AgentX Sub-agent:</td>
<td bgcolor=CCCCCC><font color=blue>ifTable -f -L</font></td>
</tr><tr>
<td></td>
<td>Standard SNMP Agent:</td>
<td bgcolor=CCCCCC><font color=blue>ifTable -M -f -L [udp[:port]]</font></td>
</table>

Note that running the sub-agent application as a master agent
will runwithout any access control. All SNMPv1 and SNMPv2c
requests will be accepted, regardless of the community string.

For that reason, when testing I run as a regular user (not root),
and only bind to the localhost interface, like so:

<table><tr><td width=20></td><td bgcolor=CCCCCC>
$<font color=blue>./ifTable -f -L -DifTable -M localhost:1161</font>
2004-04-21 21:51:47 ifTable:init_ifTable: Registering ifTable as a mibs-for-dummies table.
2004-04-21 21:51:48 ifTable: using linux 2.2 kernel /proc/net/dev
</td></tr></table>

==== Querying the agent ====

A simple ''snmpwalk'' will quickly test the module:
<table><tr><td width=20></td><td bgcolor=CCCCCC>
$<font color=blue>snmpwalk -v1 localhost:1161 ifTable</font>
IF-MIB::ifIndex.1 = INTEGER: 1
IF-MIB::ifIndex.2 = INTEGER: 2

IF-MIB::ifType.3 = INTEGER: tunnel(131)
IF-MIB::ifPhysAddress.1 = STRING: 0:0:0:0:0:0
IF-MIB::ifPhysAddress.2 = STRING: 0:30:65:cd:a3:c8

IF-MIB::ifInDiscards.2 = Counter32: 0

IF-MIB::ifOutErrors.3 = Counter32: 0
IF-MIB::ifSpecific.3 = No more variables left in this MIB View (It is past the end of the MIB tree)
</td></tr></table>

If you ran the agent with debugging, you should see something
like this:

<table><tr><td width=20></td><td bgcolor=CCCCCC>
$<font color=blue>./ifTable -f -L -DifTable -M localhost:1161</font>
2004-04-21 21:51:47 ifTable:init_ifTable: Registering ifTable as a mibs-for-dummies table.
2004-04-21 21:51:48 ifTable: using linux 2.2 kernel /proc/net/dev
</td></tr></table>
