In network engineering I have learned that the biggest lie I tell myself is that “I do not need to write this down.” That being said, when you are in the heat of troubleshooting a production issue I really try to design my systems so that I can tell what the heck something does by a label or good name. This does not replace the need for other documentation, but it does help when you are in the heat of troubleshooting a system problem. As I started supporting Unified Communications applications, I discovered there are lots of opportunities to really create a mess when you are configuring things if you do not keep supportability in mind. I want to share with you some tips that I have found helpful in naming objects specifically in Cisco Unified Communications Manager; however, similar concepts can be used for other network components such as Access Control Lists on traditional network equipment too.
When you are starting with a fresh Cisco Unified Communications Manager install, you have a blank slate. This is both good and bad. Good in that you have a lot of flexibility in the system to configure things, but bad because if you don’t put some thought into naming it can get confusing quickly. Spending some time up-front will save you some headaches down the road. Even if you don’t have a fresh Cisco Unified Communications Manager installation, you can start cleaning things up as you provision new services and go back and adapt what is in the other systems when you have time to do so.
Some of the common things you will configure in Cisco Unified Communications Manager will be: Partitions, Calling Search Spaces, Route Groups, Route Lists, Route Patterns, SIP Trunks, Device Pools, etc. First let’s get started with some basic definitions of what some of common objects are. I will also share some examples of how I like to name things to keep them easily sorted so objects of similar function are grouped together in a long list. These are just examples, and your naming convention will have to be something that works for you, your team and your specific environment. Read More »
