Can't go over 114Mbps

HI

I have search the forum and tried all the recommend this still no go.

I have 26 port switch with 2 Gig port, Gig port I am not able to get it over 114Mbit I am using SNMP Version 2 and using in/out Bits (64-bit Counts). I know I am pushing more than 130Mbps. Any help is greatly appreciated.

You need to alter the max value when you are working with a Gig port. Sorry but changing it on a port by port basis is not currently supported. For those graphs that are already created, you will need to "tune" your RRD files. See http://www.rrdtool.org for tuning the maximum value allowable for a DS in an RRD file.

May be it the usual 64bit counter problem.
try to make graph with 64bit in/out bits not the regular one.

Make sure you clear out the 32 bit one first before creating the snmpv2 one. You also need to select a device type of v2 before creating the graph.

113 is the cutoff for rollover of a 32 bit counter in under 5 minutes, so you certainly are not using 64 bit counters yet.

I deleted the device with all the data files, and just create with 64bit in /out still same.

is this the right command

Code: Select all

rrdtool tune traffic_in_110.rrd --maximum traffic_out:1000000000

You 1) need snmpv2 2) alter the max value in the template prior to creating graphs 3) see rrdtool.org for instructions on modifying existing rrd files, you must perform by the DS item.

Still having the same problem.

I am using snmpv2, I did alter the max value still same.

I even tried modifying existing rrd file still same.

And I am use the 64bit.

Any other tips,

I run quite a few graphs that go above that, I've never had to manually alter the rrd file by hand. The trick is to first create the device as V1, create a couple v1 graphs to make sure those are working, and THEN change the device to v2, and add your v2 graph using the 64 bit counter graph type instead of the regular 32 bit one.

It can be a switch/router issue also, it may not support 64 bit counters and/or the interface MIB extension for 64 counters.

For example, my 12/24/48 port Gigabit 3COM switches (32xx) work fine, but the 48 10/100 + 2 1G (4250T) switches do not. On the 4250T the 64bit counters are not there in the MIB for the Gigabit ports...

Try to snmpwalk the device, and see if there are any 64 bit counters in the MIB (it takes some time, but worth a look).

It doesn't work.

I am already getting there...

Is there any better solution ?
