snmp: operationally down
Hello all and thanks for the help.
I am using MRTG to monitor and archive bandwidth usage on my router's
ethernet ports. However, I have run into a problem with eth0 reporting
as down.
when I do the following command:
snmpwalk -v 2c -c community localhost interface
the following values are returned, which are incorrect.
IF-MIB::ifSpeed.2 = Guage32: 0
IF-MIB::ifOperStatus.2 = INTEGER down (2)
However the MAC address shows correctly,
ifInOctets has a value of 1601527752
ifOutOctets has a value of 2823843372
ifAdminStatus is correct at up (1)
I think this means that even though snmp / the system is showing eth0
operationally down, it is still keeping tabs on the passed data.
ifconfig doesn't show any obvious points to investigate, and the
router is currently running without any problems.
I have tried to use snmpset to manually set the speed and status, but
both values are not writable(I did use a rwcommunity account).
I have brought eth0 down, and then back up, but it does no good.
It may also be worth mentioning that at first eth0 was reporting
ifAdminStatus as down (2)
But when I took it down and back up it has shown correctly, and has ever since.
I am reluctant to bring the reboot the router, as it is used by our
operation 24x7
Please advise. I have looked online, but can't find any solutions.
Again, I thank you all for any help anyone can provide.
