[cisco-voip] Migrating from v7 to v9 (same cluster IPs) - getting phones to recognize new v9 cluster

Sat Jan 25 16:04:12 EST 2014

Hi Lelio,

You are correct that these models do NOT have ITL files: 7940, 7960, 7905, 7912

It would be handy for a definitive list, it used to be that the 69xx series did not have ITL files originally, until that ‘feature’ was subsequently added.

Thanks

Stephen

Thanks for the suggestion John!

We recently went through a switch reboot activity and someone from the team has a script ready to go which captures CDP neighbour output. I'll be sure to ask him to prepare that for us.

I'm hoping to learn the AXL API approach one day, but that's been allusive until now.

You do bring up a good point regarding "which phones support ITL". I looked at our 7940/7960/7912s and noticed there is no ITL file to delete while registered to a v9 cluster. The 7912 has no security option whatsoever, and the ITL section shows empty on the 7940/60.

Is it correct to assume these three models don't support ITLs?

Is there documentation that clarifies this? I will look at the 'security be default' section in the v8 and v9 manuals on Monday to see if they are listed there.

If we don't have to worry about those, that would be great.

One worry I have are the repurposed 7906 phones that Cistera uses as IP speakers which have no display or keypad attached. We may have to improvise in the event of a factory reset.

Hi,

if you are comfortable with unix you can install rancid in a linux box, put the ip addresses of the switches in a file and then do something like:
for i in  `cat switchips.file`
do
  clogin -c "show cdp nei" $i > $i.cdp
done

This will give you the mapping of switch port to phone. You could even use these files to do massive shut/no shut on the ports.

if you have also some scripting skills you could get the list of phones and the associated status/IPs using AXL.

Also pay attention to the phones that support ITL.

Cheers,
John

I hear ya about pre- and post-reporting. I'm not sure we have the budget for those tools (I'll have to check the cost), but at least I can do a few basic reports. I've modified the URL in a device listing to get about 1000 results. A few of those, cut and paste into a text file with a diff and I should be good. It will have IP addresses so we'll know the location/switch info with a bit of work.

I think best approach is to have patience here, and go with the flow ☺

If you go with pre and post reporting approach then you can quantify exactly what you need to fix, versus trying to fix a rough number of non-compliant phones.
I track down the trouble makers to their switch port and then give them a shut no shut to reset them.

As Matthew said, you may still end up on the floor doing some factory resets.

Cheers,

Tim.

I hear ya about kickstarting the gateways and such. We're planning on do restarts of all those.

My main concern is getting the phones back on line as soon as possible. I'm not a fan of just letting them go and hope they connect, especially if some take 30 min. I like the idea of the ACLs so it kick starts the phones to sort of. And it's very little work.

I'm going to be doing some mock migrations in the lab, we'll see how it goes.

I operate in environments no larger than 1000 phones but I have never changed IPs. I just shut down the old servers switch ports. As long as we do firmware ahead of time, the change hasn’t taken longer than 30 minutes. Some older routers have needed a manual kick in the pants to switch over to the new servers but it’s usually very easy. Occasionally a phone needs a factory reset. We can also revert if need be.  It’s a lot less work to shut down some switch ports than it is to setup a bunch of ACLs, reprogram DHCP scopes and dial peers, mgcp, etc. Since the new servers are VMs you can just change the network on their adapter from your lab vlan where you’ve upgraded and restored from backup to your production vlan.

The biggest concern would be if you have to revert, you are going back to before Security by Default. If you need to prepare for that it would probably be setup the new cluster with rollback enabled until you are sure everything is working. There are plenty of caveats to that, but I think we’ve covered them on the list.

HTH!

ok, i needed to wait, just a bit longer... 8 1/2 minutes before the phones re-request their cnf file.

I'm still interested in hearing what others have done.

So, still planning our v7 to v9 migration. The last time we did this, we went from v4 to v7 and changed the IP addresses of the servers. To ensure phones would go that way, we applied an ACL which blocked access to the servers, which forced a DHCP and they brought down the new TFTP address and voila, things went well.

I was thinking of doing something similar during my migration to v9. In my testing of the ACLs though (still on v7), I noticed that the phones are not really bringing down a new copy of their configuration, just re-registering.

I still have to test how phones behave when I complete the process, i.e. block ACL, unplug v7, plug in v9, allow ACL.

Will the server and phone communication be sufficient to tell the phones to download a brand new configuration file?

What have others done to migrate their phones from v7 to v9 when using the same cluster IPs?
