TFTP Redundancy

Hi Folks,

I'm wondering if it's possible to set up configure TFTP redundancy for CCM 5.1.

We ran into an issue yesterday that didn't work as I thought it would.

I currently have 2 CCMs (one pub, one sub) and 9 remote sites. Under option 150 for the remote sites, I configured the IPs for the pub/sub(10.50.0.10,10.50.0.11). By default, all phones are registered with the Subscriber. I was under the impression, during the failure of the subscriber the remote sites would attempt to re-register with the Publisher before failing over to SRST. During my failure yesterday, the remote sites failed directly to SRST. I was able to get the phones to register with the Publisher by changing the TFTP order under option 150.

Am I missing something for the redundancy to work? Failover did work as intended for any phone not using SRST.

Thanks.

Re: TFTP Redundancy

Hi Dominique,

Do you have the following commands in you SRST router config:

ccm-manager config server 10.50.0.10 10.50.0.11 (This command is for TFTP redundancy)

ccm-manager redundant-host 10.50.0.10 10.50.0.11

ccm-manager switchover-to-backup (Note: This command does not switch the gateway to the backup Cisco Unified Communications Manager server if you have set the ccm-manager switchback command to immediate and the primary Cisco Unified Communications Manager server is still running).

Hope this will help.

Thanks.

Re: TFTP Redundancy

Hi Sibusiso,

No I don't have the extra IPs in those lines.

ccm-manager fallback-mgcp

ccm-manager redundant-host ccm-pub

ccm-manager mgcp

ccm-manager music-on-hold

ccm-manager config server 10.50.0.10

ccm-manager config

This is what I have for that section.

I'll add those extra commands and test it out when I get the replacement board for my failed CCM.

Thanks for your reply.
