I look after the LAN comprising so many switches. They are all ticking along nicely.
What else can I be doing to be proactive?
For now, we check the logs, check environment.
So what else can I do to improve the network?
A network admin looking to make themselves work eh?
If you have a network installed that is performing for business needs without the need to constantly faultfind and troubleshoot then I would suggest first of all that you have done your job very well.
The next route to go, I would suggest, is to start to work up the layers of the OSI model. For instance, having done the first bit myself I decided to look at what traffic was traversing and amounts etc etc to see if there were any ways to improve the underlying ifrastructure. NetFlow was a start point to get an idea of what was traversing which then moved on to QoS policies and all that fun jazz.
I would work up at layers and you will find that you dip back down to make changes and tweeks........can of worms though, but great fun to get into optimisation once you have a solid platform.
