Monitering backplane utilization on 4503 with MRTG

[sumanth_myneni]

Hello,

I am planning to monitor the backplane utilization of the Core 4503 using MRTG software. I tried with different MIB's but couldn't monitor. Please suggest me whether we can monitor that using MRTG.The software running is

Yes, it is possible to monitor using MIB, but the the device name that has to be monitored should be entered in the SNMP server for periodic updates.

Hello,

In your Mrtg cfg file enter the following:

Target[IP address of switch-BU]:.1.3.6.1.4.1.9.5.1.1.8&.1.3.6.1.4.1.9.5.1.1.8:readcommunity@ip address of switch

This should give you the % of backplane bandwidth utilization.

Hello,

This is not working I'm afraid.

SNMP Error:

Any ideas why?

Paul,

Any idea on how to check the backplane utlization on switch. Any command.

Hi All,

There is is not command as such available right now on Cat4500 IOS for monitoring the backplane utilization.

On the Supervisors running CatOS or IOS. Normally, you can monitor backplane utilization for CatOS switches using CISCO-STACK-MIB:

http://www.cisco.com/en/US/tech/tk389/tk816/technologies_tech_note09186a0080

094a96.shtml

However, the Catalyst 4000 (IOS) does not support CISCO-STACK-MIB. Therefore, it is not

possible to monitor backplane utilization on the Cat4000 IOS via SNMP.

Thank you for your reply.

Any other ways of monitoring the backplane on Cat4500 IOS?

No as of Now, let's wait for new IP release.
