L3 Data Center Core Layer
These are chassis-based switches designed to mesh the customer access layer with the Environment core layer. The Data Core layer services seven environments - BZX Equities, BYX Equities, EDGA Equities, EDGX Equities, BZX Options, EDGX Options, and C2 Options. Uplinks use the vendor default hashing algorithm.
