Auto disable on port flaps?

[paul.matthews]

I think the answer is "no", but does anyone know a way to autodisable a port if its status changes too often?

Cat6000, I do not know SW version.

Thanks,

Paul.

Hello Paul,

I know the following works on a 6509 running IOS 12.1 (19)E1

XD0B01(config)#errdisable detect cause link-flap

Unfortunately this switch is running catos...

Hi,

On Cat6500 running CatOS, whichever ports are in use means enabled in NVRAM go to errdiale state if any of the conditions met like link-flap, udld, duplex etc.

There is no comand to tell the switch runing CatOS to put a port in errdisbla eif it violates some rule. switch detects it by default and puts the port in errdisable.

To set auto-recovery timeout u can apply the following command :

set errdisable-timeout enable all

set errdisable-timeout interval 30

I can't see a reference to link flap causing an err-disable, do you know what version that happens at?

I have now been given a little more info - the port was not doing what I consider as flapping:

2004 Aug 18 14:48:28 %ETHC-5-PORTFROMSTP:Port 1/1 left bridge port 1/1

2004 Aug 18 14:48:28 %DTP-5-NONTRUNKPORTON:Port 1/1 has become non-trunk

2004 Aug 18 14:48:40 %DTP-5-TRUNKPORTON:Port 1/1 has become dot1q trunk

2004 Aug 18 14:48:40 %DTP-5-NONTRUNKPORTON:Port 1/1 has become non-trunk

2004 Aug 18 14:49:11 %DTP-5-TRUNKPORTON:Port 1/1 has become dot1q trunk

2004 Aug 18 14:49:16 %DTP-5-NONTRUNKPORTON:Port 1/1 has become non-trunk

2004 Aug 18 14:49:55 %DTP-5-TRUNKPORTON:Port 1/1 has become dot1q trunk

it was the trunk up and down...

If it's the trunk then you need see if CatOS supports DTP flap error disable - In ios it's "errdisable detect cause dtp-flap"
