Hi,

In MIB I have a table defined with three index of type
integer.MacAddress.integer.

I had generated code using mib2c.create-dataset.conf ( version
: net-snmp-5.2.1 in Linux ). When I am sending snmpget as
myColumn.1.6.170.170.170.170.170.170.1 in agent/helper/table.c snmpd log
prints index as 1 , AA AA AA AA AA AA and 1, but if I send as
myColumn.1.170.170.170.170.170.170.1 in agent/helper/table.c snmpd
prints 1, " " and 1.=20

In the second case ( 1.170.170.170.170.170.170.1 , with out giving the
index length ) table handler is not called and for the snmpget request I
getting reply as "No Such Instance currently exists at this OID"

As per my understanding for fixed string index ( MacAddress is
OCTECT-STRING of type 6 ), no need to give the length ( 6) as prefix. If
I give MacAddress index with length mib2c table handler get called for
get/set queries, but if I give with out index mib2c handler is not
called and returned error for get/set queries )

In snmpget/snmpset request do I have to give index in some other format
for MacAddress? =20

Do I have to change any code to support get/set call if length is not
prefixed for MacAddress index ?

I had searched for some sample MacAddress index tables , I am not able
to find the same , Please some one point a place where I can get details
?

Thanks in advance ...
