Strange behavior after run snmpset to change ServerAdmin status #ServerIron #ADX

Hi,

Refer from this discussion: http://community.brocade.com/message/15047

I have tried to change the AdminStatus by using the following command:

snmpset -v 2c -c myrwstring myadx FOUNDRY-SN-SW-L4-SWITCH-GROUP-MIB::snL4RealServerRowStatus.42 i 5 FOUNDRY-SN-SW-L4-SWITCH-GROUP-MIB::snL4RealServerAdminStatus.42 i 0

42 is an index of a real server.

After issues the command, i got the flip flop email alert from the ARPWatch daemon indicated the ADX was temporary out of service for a while. However after wait for 5-10 seconds everything was just back to normal situation.

I'm using 2 ADX boxes with VRRP-e for 4 vlans. The first box is active or first 2 vlans and the second box is active for the last 2 vlans.

Any one has any experience like this?  Now I don't need to run the "snmpset" with production box any more, very strange and confuse.

I forgot to tell about the result of above command.

After issued the command and the box was not response for a while. Then, I login to the box and still see enable status of that real server.

So

  1. The command does not work ?
  2. The command has the impact for the whole box?

Upgraded to 12.303 cannot help.

My suggestion is, consider other load balancers instead of Brocade.

phuwadon,

--->>> My suggestion is, consider other load balancers instead of Brocade

If I can not drive Car, then I do not need to buy Airplane

What I want to say, your should be able to use only things what you can

....is my opinion.

I will totally agree with you if the car is completely perfect!!

This problem should consider as a bug and Brocade should address this problem in the next release.

Hi,

     Have you tried using the OID format?

To disable a real server:
snmpset -v2c -c YourRWpass YourIP .1.3.6.1.4.1.1991.1.1.4.19.1.1.6.40.40.40.40 i 5 .1.3.6.1.4.1.1991.1.1.4.19.1.1.3.40.40.40.40 i 1

If that still does not work for you, I would suggest to contact the Brocade TAC for the answer.

Thanks

Michael.

As I can see, Michael Schipp coming me before with a suggestion to contact Brocade Support.

To you comment, about  --->>>...if the car is completely perfect!!

if this feature what you want to set and/or use is Supported, then is most probable - this is my experience - in 99% your/user have made some settings wrong in the config.

is this the problem, then "is the car completely perfect"

Thank you for your suggestion.

I'm currently working with Brocade TAC support and just posted to the community to check for any possibility that may exists. Right now, I'm afraid to run the "snmpset" command to the box because the box will shortly disappear for 1-2 minute and the ADX boxes are running in production network.

However I will try as your suggestion during low peak period. Thanks again.
