I stumbled into a Network Administrator position for a county school system and am pretty overwhelmed and at a loss of where to start learning and improving. It was kind of being at the right place at the right time as people retired/found new jobs.
After reading through some info on this subreddit I would say I know basic networking. How to configure a switch, setting up vlans and configuring APs as well as trouble shooting your basic network issues if something stops working, but I feel very unqualified. There seems to be so much that I still don't know that I'm not sure what I should start learning into first to better prepare for future disasters/issues.
A quick rundown on the layout of my network, I have 32 locations to manage all with there own router with a private fiber line to our ISP which then comes back to a central router. Then that gets sent to a state department to be filtered through a firewall. DHCP and DNS is done through windows servers. We have multiple wireless controllers depending on the brand of APs the location has. The network is vlan'd with a basic Wired, Wireless, Cameras, VoIP and Mangement format.
Other than vlans, nothing else is really configured on the switches which are a hodgepodge of cisco and extreme equipment ranging from brand new to 15 year old nortel switches; our APs are either Cisco or Extreme
The only management tools that I currently have is an ancient version of Scrutnizer that just measures bandwidth from the routers.
