Hi Jon

would you name me the Case ID? So I can refer to it? While I open a case?
DM is fine as well. If you like..

Thanks
Basile

Hi there,

 

No apparently it is a feature J We are running version 5.6k but they re-produced it on their own test MLXe switches running newer versions (we can’t run greater than 5.6 due to hardware limitations). Might be worth some other people raising it so that it gains some traction within Brocade?

 

Thanks,

Jon

Hi Jon

thanks for the reply. Yeah I was referring to the high CPU issue. So seems to be a doable way to disable the FOUNDRY-BGP4V2-MIB.

Has Brocade named an Ironware release which it is fixed?

Thanks

Basile

Hi there, we had exactly the same problem last week with some XMR routers! Looking at the SVN log, it looks like the default behaviour for Brocade devices changed around 9/11/16 (from memory) to use the FOUNDRY-BGP4V2-MIB.

 

The cause of the problem appears to be the MIB returning a full BGP table via the SNMP Walk (we saw high process usage for the SNMP and BGP processes, presume you see the same?).


Our workaround is to disable the FOUNDRY-BGP4V2-MIB in the device properties and just use the default BGP4-MIB. Also we didn’t have to reboot anything, we found applying an SNMP ACL to *not* allow the Observium box to hit the router reduced the CPU usage after about 30 minutes so that might help you out also.

 

I actually raised this via Brocade and they confirmed the issue, presume it would be possible to create an SNMP View on the router to skip that part of the MIB but not looked into it yet.

 

Thanks,

Jon

Hi All

running 5.6h. Target Release Train, as far as I understood...

SNMP clear cache -> CPU still high
SNMP unconfigure -> CPU still high

reload device -> all fine again

I'm not able to send you a debug output as of now...

I would need to reboot my devices again to have SNMP working again...

Thanks

Basile

Some feedback:

 

I'm seeing a steady stream of this kind of event log message every  5 minutes from each of my Netiron devices doing BGP:

 

Bgp-peers: 2 updated, 28 unchanged.

Forced discovery module(s): bgp-peers

 

It's not causing any issues other than filling our Obs event log.

Hi Basile,

 haha, this mean vendor added support for this table in snmp, but never test this :)

Or firmware on your device old :)

Pls show debug for poller (with latest revision!):

./poller.php -d -m os,processors,bgp-peers -h <device>

Hi Mike

this update left my Brocade CER hanging with a high CPU consumed by SNMP.

I went back to revision 8234.

Now I try to recover the CER...

Kind regards

Basile

Try with latest revision r8236. Professional (rolling). :P

Hi,

 yes, I was see documentation, but anyway still did not find any device where it exist..

Better if you provide snmp access to device where this bgp tables exist for my dev:
77.222.50.30
2a02:408:7722:5030::5030

Dear Mike,

 

Apparently, it is supported according to their documentation (see attached).

 

 

If needed, I can test for you if you provide me with the commands.

 

Best regards.

Dear Community,

 

I was wondering why I wasn’t able to recover any information about IPv6 BGP sessions from our core routers (Brocade MLXe / CER).

 

 

I checked related MIB documentation from our vendor, and it seems that draft-ietf-idr-bgp4-mibv2-12 MIB is supported for our OS version (running NetIron 5.7e).

Just I still not have access to any device which support this MIB/draft..

 

Can I ask from the community if there is a debug version that I can run in order to make sur of that ?

 

Thanks.
