Hello,
We had the same problem with our Cisco 4006/4506 switches which didnt
have support for the STACK-MIB.
One option is to check whether newer version of the switch IOS software
has support for those MIBs. If so, you can
upgrade the IOS and it should work.
If not (in our case), we commented out the code in the emulab software
which did the port control.
The only disadvantage is that you cannot control the port speeds of the
switch or NICs and you are stuck at a certain
speed (1Gbps or 100Mbps depending on your switches/NICs). You will have
to manually set the port speeds to
the value from the console.
Utah folks: Maybe there should be some code to check whether switches
support the MIBs and if not it would neuter
the port control code?
HTH,
Adit

Hello Mr Ricci,
First of all, thanks for your precious feedback.I found the OIDs
that are used in emulab source code.But I am struck with the issue of
porting those OIDs. My confusion is that- a particular OID belongs to a
particular MIB and do a particular job.So is there any other way that
there may be another OID of another MIB that performs the same job as
the previous OID and I should replace the OIDs of some absent MIB with
the OID of present MIB? Would you kindly advice me whether my
understanding is correct or not? Or should I go for adding those
missing MIBs in N5000? (actually the problem with this alternative is
that I cannot find a way to add MIB to cisco switch.I found the way to
add MIB to NMS pc, but not to the switch). I am sorry if I am too naive
in asking these questions.

Unfortunately,
despite their names, the STACK and VTP MIBs do provide
functionality that we use on single switches, so they are needed even if
you have one switch. I don't think that any of the MIBs we use are
required only for multi-switch setups.
