Each time a tun falls and rises again, a new entry appears in the
if-MIB, and it even has the same description!

    OK, that sounds *good* to me...

    Not sure what the problem is.  PLease clarify.

What this sounds like to me, is a situation where the index
of the interface keeps changing, whenever the interface is
taken down and brought back up again.

Something like as follows:

$ snmpwalk ifName
ifName.27 = "if0"
# ifconfig if0 down
# ifconfig if1 up
$ snmpwalk ifName
ifName.39 = "if0"

This
is exactly my problem, and my case is same with interfaces "tun"

There is no
workaround for this?

look that:

snmpwalk

IF-MIB::ifDescr.1 = STRING: lo

IF-MIB::ifDescr.2 = STRING: eth0

IF-MIB::ifDescr.3 = STRING: sit0

IF-MIB::ifDescr.13499 = STRING: tun1

IF-MIB::ifDescr.13502 = STRING: tun0

IF-MIB::ifDescr.13503 = STRING: tun0

IF-MIB::ifDescr.13504 = STRING: tun0

IF-MIB::ifDescr.13505 = STRING: tun0

(...)

IF-MIB::ifDescr.13542 = STRING: tun0

IF-MIB::ifDescr.13543 = STRING: tun0

IF-MIB::ifDescr.13544 = STRING: tun0

There are something around 44 tuns in IF-MIB, but this server just uses
2.
