[cisco-voip] UPPERCASE lowercase host names

[NateCCIE]

I personally have not seen a problem based on mixed or uppercase and UCCX, I just had a guy at TAC say I should change it because it will cause me lots of problems.  So I did on that system, but then I have other customers who have uppercase that I did not install, but have not run into problems.  I just was surprised  when he pulled out a doc to support his claim that lowercase was required.

 

I have seen problems with certificates and mixed or uppercase domains, where the system did not think the SANs matched because the CA set all of the domains to lowercase, but the UCOS thought it should be uppercase.

 

So now I am very particular about making sure domains are lowercase.  Hostnames, not so much.

How strongly enforced is that UCCX hostname in lowercase requirement?  I have seen upper case used all over the place.

 

I have also seen, someone named their Unity Connection server "ciscounity" and then they had to rebuild it. (this was during installation)

*  Be aware that the field values (namely hostname and passwords) that you enter while you are running the installation program are case sensitive. Hostname must be in lower case, and the character limit is 24 characters.

Hi Matthew,

I think you could be referring to a restriction that was pre CM 4.x. But from CM 5.x I think it just matters to make it consistent. Where I think it could be a problem is if let's say you have a system with hostname in uppercase and proper DRF backup. Then due to system failure, you need a DRF restore but during install you use the hostname in lowercase, then I think you will have problems.

Hi All,

 

I’m sure I read somewhere on a Cisco Doc that all UC hostname should be set up using lowercase name. But I can’t seem to find anything documented with the exception of CWMS documents.

 

Can anyone clarify this and hopefully point me to a relevant document.
