4006 BackPlane Utilization

[Kurgoth]

I was wondering if anyone had found the backplane OID on a Cisco Catalyst 4006? I have walked the box and can only find one that returns the name value of the backplane.

Any Help would be appreciated.

A quick search of groups.google returns the following thread.

http://groups.google.com/groups?hl=en&l ... e%2BSearch

(If the URL fails, the keywords of my search were: cisco 4006 backplane utilization MIB)

I did a quick SNMP get of my 4006 and as able to gather some of the stats mentioned in the thread.

[Kurgoth]

OK i went to the link and possibly I am going about this all wrong.

I attempted an snmpget on the oid 1.3.6.1.4.1.9.5.1.1.32.1.3
and it returns a value not found. Could this indicate it isn't there or are there numbers to be added to the end. Just when i think i have this down, something new comes along.

It is quite possible that the oid is from a more recent release and/or image type (enhanced, etc.)

I am not an expert on this, so please don't take this for gospel.

The 4000 series switch is an older model switch that uses a single backplane. Acording to this article at Cisco http://www.cisco.com/en/US/partner/tech ... 4a96.shtml

you should be using the systrafficmeter mib variable (.1.3.6.1.4.1.9.5.1.1. and not the one that you posted.

The variable that you posted is an indexed variable, so you would have to add a 0 or 1 to the end of the MIb to select the appropriate backplane. But this only applies to the x500 series switches.

Now would some CCIE please confirm what I just said, or atleast let everyone know that I'm completely off track.....

you're absolutely correct. The indexed value is for multi backplane chassis.


the link requires a partner login though, so i'm pasting the itneresting part of it here for those who don't have cco logons.

For traditional Cisco switches that have a single backplane such as the Catalyst 5000 series, sysTraffic from CISCO-STACK-MIB MIB provides the system backplane utilization. The sysTraffic measurement equates roughly to the meter of the same name on the supervisor card.


.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 }
For switches that contain multiple backplanes, such as the Catalyst 5500, use the sysTrafficMeterTable from the CISCO-STACK-MIB.

.1.3.6.1.4.1.9.5.1.1.32
sysTrafficMeterTable OBJECT-TYPE
-- FROM CISCO-STACK-MIB
DESCRIPTION "The system traffic meter table. This table lists the traffic meters available in the system."
::= { iso(1) org(3) dod(6) internet(1) private(4) enterprises(1) cisco(9) workgroup(5) ciscoStackMIB(1) systemGrp(1) 32 }

Sorry about that! Here it is without the partner login.

snmpget -c string -v 2c name.4006.org 1.3.6.1.4.1.9.5.1.1.8

Would this not return the value?

[egarnel]

Which are you running?

I have found that the native IOS (Sup III, IV) has a lot more info to offer up
in terms of monitoring.

[kurgoth]

Looks like we are running the ws-x4515 Supervisor Engine IV.

[kurgoth]

Supposedly this is the right mib, found it on a couple sites.

1.3.6.1.4.1.9.5.1.1.8 for the backplane utilization of the 4006. I am trying to figure out where you plug this into cacti to graph it. Is there a place i can look for these steps, or do i need to write a script and use the script to graph this data?

[Lux]

Go into data templates and look at the Cisco 5 minute CPU template. I simply copied that template, renamed it to Catalyst Backplane and changed the mib variable.

Mike

[kurgoth]

i added the data template, do i need a "." at the beginning of the mib for the value, as it doesn't seem to be gathering any data.

[Lux]

Yes, you need the "." at the beginning of the mib.

[kurgoth]

Normally, you can monitor backplane utilization for CatOS switches using CISCO-STACK-MIB http://www.cisco.com/warp/public/477/SN ... _util.html . However, the Catalyst 4000 (IOS) does not support CISCO-STACK-MIB. This can be verified by using the MIB Locator tool. Specifically, refer to http://tools.cisco.com/ITDIT/MIBS/Advan ... IT1=Submit . Therefore, it is not possible to monitor backplane utilization on the Cat4000 via SNMP.
