Yeah, sure. Of ifindices.

The indices of the table in questions are ENTITY-MIB entPhysicalIndex 
values and though they'll probably stay constant on a given box *WILL* 
vary across boxes for the same components in the same slot positions, 
which I believe was the OPs problem:

"""But the 4001 can change between different switches (6500). Anybody 
can explain how? or can I use a other OID?"""

SNMP tables indices don't remain stable. Software that pretends they do 
is broken.
