Hello, I'm having a problem with supporting counter64 values. I set up the counter64 structure with high and low values and return it as in: return (u_char *)&c64; from the var_func() of the appropriate variable. However when I query this variable it get's a no value returned by agent error. I have verified control is being transferred into my var_func() and a value is being returned. Could someone throw some light as to what's going on or is there any example of counter64 values? I'm using ucd-4.2, running on NetBSD. thanks. __________________________________________________ Do You Yahoo!? Get email at your own domain with Yahoo! Mail. http://personal.mail.yahoo.com/ |

Hello! I have implemented an IFMIB (IfXtable) with folllowing
Counter64 types.
-----------
struct variable4 ifmib_variables[] = {
{IFNAME, ASN_OCTET_STR, RONLY, var_interfacesx, 3, {1, 1,IFNAME}},
{IFINMULTICASTPKTS, ASN_COUNTER, RONLY, var_interfacesx, 3, {1, 1,IFINMULTICASTPKTS}},
{IFINBROADCASTPKTS, ASN_COUNTER, RONLY, var_interfacesx, 3, {1, 1,IFINBROADCASTPKTS }},
{IFOUTMULTICASTPKTS, ASN_COUNTER, RONLY,var_interfacesx, 3, {1, 1,IFOUTMULTICASTPKTS }},
{IFOUTBROADCASTPKTS, ASN_COUNTER, RONLY, var_interfacesx, 3, {1, 1,IFOUTBROADCASTPKTS }},
{IFHCINOCTETS, ASN_COUNTER64, RONLY, var_interfacesx, 3, {1, 1,IFHCINOCTETS}},
{IFHCINUCASTPKTS, ASN_COUNTER64, RONLY, var_interfacesx, 3, {1, 1,IFHCINUCASTPKTS }},
{IFHCINMULTICASTPKTS, ASN_COUNTER64, RONLY, var_interfacesx, 3, {1, 1,IFHCINMULTICASTPKTS }},
{IFHCINBROADCASTPKTS, ASN_COUNTER64, RONLY, var_interfacesx, 3, {1, 1,IFHCINBROADCASTPKTS }},
{IFHCOUTOCTETS, ASN_COUNTER64, RONLY, var_interfacesx, 3, {1, 1,IFHCOUTOCTETS }},
{IFHCOUTUCASTPKTS, ASN_COUNTER64, RONLY, var_interfacesx, 3, {1, 1,IFHCOUTUCASTPKTS }},
{IFHCOUTMULTICASTPKTS, ASN_COUNTER64, RONLY, var_interfacesx, 3, {1, 1,IFHCOUTMULTICASTPKTS }},
{IFHCOUTBROADCASTPKTS, ASN_COUNTER64, RONLY, var_interfacesx, 3, {1, 1,IFHCOUTBROADCASTPKTS }},
{IFLINKUPDOWNTRAPENABLE, ASN_INTEGER, RWRITE, var_interfacesx, 3, {1, 1,IFLINKUPDOWNTRAPENABLE }},
{IFHIGHSPEED, ASN_GAUGE, RONLY, var_interfacesx, 3, {1, 1,IFHIGHSPEED }},
{IFPROMISCUOUSMODE, ASN_INTEGER, RONLY, var_interfacesx, 3, {1, 1,IFPROMISCUOUSMODE }},
{IFCONNECTORPRESENT, ASN_INTEGER, RONLY, var_interfacesx, 3, {1, 1, IFCONNECTORPRESENT}},
};
----------
in init_interfaces();
------------
REGISTER_MIB("mibII/ifMIB", ifmib_variables, variable4, \
ifmib_variables_oid);
---------
An extraction from var_interfacesx() :
----------
case IFHCINOCTETS:
#ifdef STRUCT_IFNET_HAS_IF_IBYTES
long_return = (u_long) ifnet.if_ibytes;
#else
#if NO_DUMMY_VALUES
return NULL;
#endif
long_return = (u_long) ifnet.if_ipackets * 308; /* XXX */
#endif
return (u_char *) &long_return;
-------------
Now the question.
The agent stops completely when i issue snmpget of version 2c and it wants to process the
first Counter64 value. Have I forgotten do do anything or initialize values or register the mib the proper way?
Thank you!
/Mattias

Since the lack of input from the list I am now changing
the counter64 types to 32-bit counter (SMIv1) as a temporary
solution just to get it running. I know it is a horribile crime
against the standards but I can't afford a showstopper like this.
