NETWORK OUTAGE

[ Edited ]

HELLO

 

IN CONFIGURING A VRRP IN PRODUCTION ENVIRONMENT, THE PRIAMRY CONTROLLER IS A 3400 WITH AOS 5 VERSION CODE.

 

IN THOS CONTROLLER THE VRRP IP IS 192.,168.170.2 AND ALL THE RAPS ARE UP AND WORKING FINE.

 

BUT WHEN I CONNECT THE BACKUP CONTROLLER(3200) TO THE NETWORK ALL THE NETWORK IS DOWN I MEAN VOIP, DATA, PtP LINKS, RAPS ALL IS DOWN.

 

WHAT IS THE COMMNAD TO DEBUG THIS PROBLEM, I WANT TO CONNECT THE 3200 AGAIN AND TROUBLESHOOT WHAT IS HAPENING INSIDE THE BOX

 

URGENT, THANKS

We will need more information.

 

Run the following commands on the primary controller and post the output:

 

show vrrp

show ip interface brief

 

Then bring up the other controller, without it connected to the network (console into it). Run the same commands and post the output.

 

It sounds like you might have a duplicate IP somewhere. Also, are your AP's pointed to the VRRP address as their LMS?

Re: NETWORK OUTAGE

Huh. So VRRP isn't configured on the 3200 yet? If you do a show run | begin vrrp, you should see this on the 3200:

 

vrrp 1
authentication password
ip address 192.168.170.2
vlan 170
no shutdown

 

 

Is that in the show run on the 3200?

Thanks,

Re: NETWORK OUTAGE

To be safe, you should open a support case so that they can troubleshoot this live.  There are a number of factors that could be at play and you cannot afford an outage based on the limited information in the forum.

I want ot mention two things first before we set up the VRRP on the backup

 

  • When you add the backup , make sure that there is no spanning tree issue, check for any loops in the network. On Aruba controllers spanning tree is enabled by default.

 

  • When you are taking about RAPs, they connect over the internet. So your LMS ip should be a public interface and then your external firewall can nat this IP to the VRRP instance between the master and the backup controller.

 

  • Configure VRRP on the backup controller with the lower priority than the master else the backup wil become the master and the  database will sync from backup to master
