That's not how I interpreted his issue at all and I'm a bit dubious about it. The problem interface was a Serial interface, possibly the only upstream connection. check_snmp will behave this way if the router is unreachable. I've never personally experienced this 'disappearing' interface problem or non-responsiveness with any kind of physical connection (Serial, (Fast)Ethernet, etc), only virtuals such as ISDN Virtual interfaces, which are expected and even those have never caused SNMP to be non-responsive. I do perform somewhat extensive checking of interfaces via SNMP (several thousand). Michael: Can you clarify? I'm interested in knowing if this is something I need to be concerned about.

No.
As he noted, the problem is that the Cisco doesn't behave properly. If
the port is down, the Cisco should *say that it is down*, rather than
simply ceasing to respond properly.
But that's what it does, and that's what you're seeing.
Marc, I gather provided a workaround, but that will likely obscure
those circumstances when the entire router drops dead. Well, at least,
the historical logs will say the wrong thing.
No way to do better.
I concur: contact TAC; open a ticket.
Cheers,

There's no command line option to change this behavior. If you wish to
exit with a CRITICAL status instead of UNKNOWN you'll need to edit the
source for check_snmp.c around line 300 and replace --
if (found == 0)
die (STATE_UNKNOWN,
_("%s problem - No data received from host
\nCMD: %s\n"),
label,
cl_hidden_auth);
with
if (found == 0)
die (STATE_CRITICAL,
_("%s problem - No data received from host
\nCMD: %s\n"),
label,
cl_hidden_auth);

Re: [Nagios-users] Problem with Router status in notification.
Hi
thanks for your input.But the port was actually down.Bt i want notification
saying that port is down rather than snmp unable to collect data
So is any extra parameter such as -s /-r is required in my check_snmp
command.

No. You need to get another router. Cisco in their infinite wisdom will
give odd results on some interfaces if they are down. I have seen cases
where the interface is there if it's up but when it's down the interface
is gone as far as SNMP is concerned.
I suggest you open a supprt ticket with Cisco on this odd behaviour.
It's their problem and they need to fix it.

[Nagios-users] Problem with Router status in notification.
Hello list
I am using nagios 3.0.I am having problem in getting notification for any
port down in my router.I am using snmp to collect data.
define service{
usegeneric-service; Inherit values from a template
host_namehongkong-gw1
service_descriptionPort 10 descr adminstatus operstatus
check_commandcheck_snmp! -C public -o
ifDescr.14,ifAdminStatus.14,ifOperStatus.14
this gives me output
SNMP OK - Serial0/0 up(1) up(1) "FTIL1566 Connection to Londonpop-gw1
Ser0/3"
now when the port goes down , i recieve messege saying SMNP data not
recieved from host , problem unknown.but i want that it should give me
messege that the port is down.
is there anything i need to change in the above check_snmp command?
appreciate your help !!
regards
Michael
