measuring stack-load on 3750

[jack.kuppers]

Hi everybody,

I'am rather new to this subject, so forgive me the maybe silly question (although I need an answer ... ;-)

We are stacking several 3750's to one virtual switch. I already know that the max load on the backbone will be 32 Gbps, but we want to know when we are near that point.

How can I get the stack/backbone-load of the virtual switch with IOS commands or even better via SNMP calls (do I need a specific MIB ?)

Thanks in advance,

Jack #

There is an OID called sysTraffic in CISCO-STACK-MIB

.1.3.6.1.4.1.9.5.1.1.8

sysTraffic OBJECT-TYPE

-- FROM CISCO-STACK-MIB

SYNTAX Integer (0..100)

MAX-ACCESS read-only

STATUS Current

DESCRIPTION "Traffic meter value, i.e. the percentage of bandwidth utilization for the previous polling interval."

::= { iso(1) org(3) dod(6) internet(1) private(4) enterprises(1)

cisco(9) workgroup(5) ciscoStackMIB(1) systemGrp(1) 8 }

The sysTraffic shows the same value as the switch load meter on the front of the switch.

Thanks for the info, but I'am afraid that this is not working.

This is what I get with snmpwalk .1.3.6.1.4.1.9.5.1.1

enterprises.cisco.workgroup.ciscoStackMIB.systemGrp.sysTraffic.0 = 0

enterprises.cisco.workgroup.ciscoStackMIB.systemGrp.sysTrafficPeak.0 = 0

enterprises.cisco.workgroup.ciscoStackMIB.systemGrp.sysTrafficPeakTime.0 = Timeticks: (0) 0:00:00.00

enterprises.cisco.workgroup.ciscoStackMIB.systemGrp.sysEnableChassisTraps.0 = 0

enterprises.cisco.workgroup.ciscoStackMIB.systemGrp.sysEnableModuleTraps.0 = 0

enterprises.cisco.workgroup.ciscoStackMIB.systemGrp.sysStandbyPortEnable.0 = 0

Maybe some more info about the switch can be helpfull :

Model number: WS-C3750G-24TS-S

System image file is "flash:c3750-i9-mz.122-20.SE1/c3750-i9-mz.122-20.SE1.bin"

Thanks,

P.S. We don't have a load meter on the switches ...
