L3 Customer Access Layer

C1 Options employs both 1G and 10G dedicated switches that serve as the network access point for customer connections. The number of switches is largely based on customer demand. Uplinks use the vendor default hashing algorithm.

NY4	6	10G	4x100G	Arista	DCS-7050SX3-48YC12	Cut-Through*
NY5	6	10G	4x100G	Arista	DCS-7050SX3-48YC12	Cut-Through*

*Switching mode is effectively store-and-forward one way due to speed change 1G to 100G or 10G to 100G.
