introduction
The data network in the LIC contains three ethernet switches. Each provides dozens of data sockets to each shelf of the rack.
- ces01 handles traffic for the biz01 network.
- ces03 handles traffic for the biz02 network.
- ces03 handles traffic for the adm01 network.
ces01 VLANs (Virtual Local Area Networks)
The ethernet switches in the LIC pretend to be many switches by creating VLANs. I edited the ces01 configuration to create these VLANs.

ces03 interfaces table
The ces03 interfaces table shows how to plug cables into a 48 port switch.
