The Content App Services Layer
A circuit on the CSS is a logical entity that maps IP interfaces to a logical port or group of logical ports, for example, a VLAN. Each VLAN circuit requires an IP address. Assigning an IP address to each VLAN circuit allows the CSS to route Ethernet interfaces (ports) from VLAN to VLAN.
The tests mapped to the Content App Services layer reports key statistics related to the performance of the circuits and IP interfaces configured on CSS.
