Hello All,

I want to disable the ifTable and ifXtable implementation in the master =
agent
and register a private handler for the two oid in my sub-agent to handle =
the two mibs.=20

the two oids are:

/*-----------------------------------------------------------*/
static oid aSubagentIfTable_oid[] =3D {1,3,6,1,2,1,2,2};
size_t aSubagentIfTable_oid_len =3D OID_LENGTH(aSubagentIfTable_oid);

/*-----------------------------------------------------------*/
static oid aSubagentIfXTable_oid[] =3D {1,3,6,1,2,1,31,1,1};
size_t aSubagentIfXTable_oid_len =3D =
OID_LENGTH(aSubagentIfXTable_oid);

At the run time and at the sub-agent handler registration time these =
errors are displayed
on the window where the sub-agent is running in the forground:
registering pdu failed: 263!
registering pdu failed: 263!

I assumed that there is one of these messages for each registeration =
call I have in my sub-agent.
my registration call code for ifXTable is as follow:

netsnmp_mib_handler* handler =3D netsnmp_create_handler(
"aSubagentIfXTable", &aSubagentIfXTable_handler );

if (!handler)
{
snmp_log(LOG_ERR,
"%s | agent create IfXTable MIB oid handler failed\n", =
__FUNCTION__);
return -1;
}

regInfo =3D netsnmp_handler_registration_create( "aSubagentIfXTable", =
handler,
aSubagentIfXTable_oid, aSubagentIfXTable_oid_len,
HANDLER_CAN_RWRITE);

if (!regInfo)
{
snmp_log(LOG_ERR,
"%s | agent create IfXTable MIB oid handler registration =
failed\n", __FUNCTION__);
return -1;
}
=20
retVal =3D netsnmp_register_handler(regInfo);
if ( retVal !=3D MIB_REGISTERED_OK ) {
snmp_log(LOG_ERR,
"%s | agent IfXTable handler registration failed \n", =
__FUNCTION__);
return -1;

-------------------------------------------------------------------------=
-----------

similar code immediately after this is for ifTable oid registration.

I assumed that I have to recompile the master agent with =
--with-out-mib-modules=3D"if-mib ip-mib tunnel" and =
--disable-mfd-rewrites
options to disable the if-mip and ip-mip implementation from the main =
agent. this resulted in smaller main agent and smaller libnetsnmpmibs.so =
files.

after restarting both agents only one of the "registering pdu: 263!" =
message was displayed.

In addition and when testing with snmpwalk command the ifTable request =
is not passed to my sub-agent while the ifXTable request is.

Is there anything else left for me to do to have the master (main) agent =
call my ifTable handler for all snmp requests on this mib?

thanks
Bernadette Eyre

I changed the makefile and added mibII/interfaces to the list of the =
mibs to disable.
here is the configure command:
configure --with-install-prefix=3D$(BUILT_BASE)\
--prefix=3D/ --host=3D$(CCPREFIX) --target=3D$(CCPREFIX) =
--disable-perl\
--disable-embedded-perl --disable-perl-cc-checks \

--with-sys-contact=3D"contact"\
--with-sys-location=3D"location" --with-logfile=3D"path" =
\

the compilation failed during the snmpd link
./.libs/libnetsnmpagent.so: undefined reference to `vacm_standard_views'
collect2: ld returned 1 exit status
make[2]: *** [snmpd] Error 1

is mibII/interfaces option valid?

I haven't been able to disable the processing of the ifTable from the =
main agent.
if you know how please help.

Starting the agent using "-I-ifTable -I-ifXTable" should do that, I think.
