Monitoring Tengigabit

lwn-nenzing · ‎02-15-2006

I get from my monitoring tool wrong informations about th Tengigabit interfaces and Portchannel. Its running on 6506 with WS-X6704-10GE and WS-SUP720-3B. I installed snmpv1 there. Or I have to use a special MIB?

Are there other possibilities to get a interface updated faster. At the momenent each 30 sec its updated.

What MIB objects are you polling? Since this is a Tengigabit interface, you have to poll the 64 bit counters using snmp v2c.

For example, ifHCInOctets (1.3.6.1.2.1.31.1.1.1.6) instead of ifInOctets (1.3.6.1.2.1.2.2.1.10)

If the device is running IOS, try the following command (may be hidden):

snmp-server hc poll 1000

This will improve your update interval.

When i make a snmpwalk from the Commandline with the MIB ifHCInOctets i get the correct results back. I tried now different tools to get the same back, but always with an error. Is this snmpv2c configuration i have on the switches correct?

snmp-server group GROUPNAME v2c

snmp-server community COMMUNITYNAME RO

snmp-server user USERNAME GROUPNAME v2c

snmp-server group and user syntax is typically used for SNMPv3 configuration and is probably unnecessary for your needs.

If you simply use

snmp-server community SNMPRO RO

that will turn-up both SNMPv1 and v2c stacks.
