Over Subscription Ratio
(Layer 3 distributed core deployment
topology only)
For the layer 3 deployment the following over-subscription ratios are

• 1:1
• 3:1
• 4:1
• 5:1
Resiliency in Access Devices Configures Virtual Router Redundancy Protocol (VRRP) on the downlink.
10 Gb Cable Type for Access Tier This option is applicable only for the topologies in which S4810 and S4820T
can be swapped with each other.
• SFP+
• RJ-45
