What should I do now ?

 

 

 

On the current master, please post the output of "show switches"

You don't have master redundancy configured properly. You should see two controllers from the master; the master and the standby

Soory to say I disconnected the standby and remove the VRRP steup. Once I will make the setup again I will share the update.

 

 

Dear Joseph,

I have checked the vrrp configuration still the output is same. You are requested to please mentioned the steps which are useful to rectify the issue.

 

Looking forward

 IMH-MC3600 is master

Master redundancy has to be setup correctly for database sync to work.  That is different from VRRP redundancy.

 

 

 

What information is required to create the  master redundancy and data synchronization ?

 

Can you please mentioned the steps to create the master redundancy ?

 

your cooperation in this regard will be highly admirable.

 

looking forward.

(IMH-MC3600) #show master-redundancy Master redundancy configuration:

VRRP Id 20 current state is MASTER

Peer's IP Address is 10.20.0.2

Peer's IPSEC Key is ********

(IMH-MC3600) #

 

(IMH-Standby) # show master-redundancy

Master redundancy configuration:
VRRP Id 20 current state is BACKUP
Peer's IP Address is 10.20.0.1
Peer's IPSEC Key is ********

(IMH-Standby) #

 

 

 

If you type "show switches" from the master and you do not see the master AND the standby, master redundancy is configured wrong....

What information is required to create the master redundancy and data synchronization ?

 

Can you please mentioned the steps to create the master redundancy ?

 

your cooperation in this regard will be highly admirable.

Dear joseph 

 

for master redudancy we have configured th vrrp according to the steps mentioned in the link provided by you. But still the output is same. :(

 

 

The key is to execute this, first on the master:

 

config t

master-redundancy vrrp <vrrp id>

peer ip address <backup master>

master-ip <backup master>  ipsec <key>

 

 

Then execute on the backup master

 

config t

master-redundancy vrrp <vrrp id>

peer ip address <master>

master-ip <master>  ipsec <key>

 

 

Please find the below snapshots

 

 

 

 

 

 

You should remove the master-redundancy configuration from the backup and re-apply it.  It is saying that the master ip address is the VRRP address and not the master's ip address.

Can you please explain.... On the backup controller what changes are required ?

 

 

Please open a TAC case about this.  I want to make sure you are not running into a bug.

You are requested to please fill my configuration.

 

Master controller vlan 20 ip 10.20.0.1

Backup controller vlan 20 ip 10.20.0.2

VRRP 20  ip address 10.20.0.3

Key abc@2015

 

 

config t

master-redundancy vrrp <vrrp id>

peer ip address <backup master>

master-ip <backup master>  ipsec <key>

 

 

Then execute on the bakcup master

 

config t

master-redundancy vrrp <vrrp id>

peer ip address <master>

master-ip <master>  ipsec <key>

 

 

 

On the backup master:

 

config t

master-redundancy

no master-vrrp 

no peer-ip address

master-vrrp 20

peer-ip-address 10.20.0.1 ipsec abc@2015

 

If that does not work, please try using a key that does not have an @ sign.

 

According to your guidance I matched all the steps with my current configuration. I also changed the key but the outcome is negative.

 

 

hi

please run the following two commands on the backup controller and paste here:

 

show process monitor statistics

show processess | include db,mys

show log error | include dbsync

 

you may be hitting known bug 116628, the output from the above commands will allow me to confirm it

 

regards

-jeff

 

Please note your desired information in the attached file naming  ""Logs"".

 

 

 

 

 

Please open a support case so that you can get help.

+1 to what Colin just mentioned, time for a support case - the logs attached do not show any match with the known issue, so something else is going on.

It looks like the keys in your VRRP 20 are mismatched:

 

Invalid advertisement received for VRID 20, Mismatched authentication type
