SUP failed over manually, voice service failed after FAILOVER, started accessing old voice vlan which was removed from config

Hey guys, 

 

I am pretty sure, my subject is kinda confusing. Sorry about that. Here is what happened. 

1. 4510r with Supervisor V 1000BaseX, switched over to standby Sup, then reseated Active SUP, once reseat complete, switched again to get the reseated SUP up and running as Active SUP. 

2. a simple maintenance which was supposed to cause no outage and it did not cause any outage as well. 

3. however, what i did not notice was, even though the voice vlan was configured to access 2353, they were accessing vlan 453. 

4. the change was made 2 weeks prior to this maintenance where voice vlans were previously accessing 453 and they were all changed to access 2353. configs were saved. 

5. however, after the maintenance, the running config showed that they were acessing 2353 but when checking the mac address on the interface, it was seen accessing 453. 

6. the fix was to remove the config and re add it , that fixed it. 

 

Has anyone else experienced the issue ? What really happened there ?
