• Type 2: 10 Gb Blade Switch (MXL)
• Type 3: 10 Gb Top of Rack Deployment (mVLT)
For more information about VLT, see Overview of VLT , and Key Core Design Considerations for VLT . See also Getting
Started.
Use the following table as guideline to select the appropriate Layer 2 VLT fabric design.
NOTE: With a Layer 2 VLT fabric, the uplinks come from the first two spines.

Function Type 1: 1 Gb ToR Type 2: 10 Gb Blade Switch (MXL) Type 3: 10 Gb ToR (mVLT)
Spine device S4810 S4810 Z9000
Leaf device S60 or S55 MXL switch S4810 or S4820T
Max # of spines 2 2 2
Max number of leafs 44 11 (without stacking) and 10 (with
stacking)

Uplink ports 4 x 40 Gb 8 x 40 Gb 8 x 40 Gb
Interlink ports 88 x 10 Gb 80 x 10 Gb 52 x 40 Gb
Max number of leaf
ports
2304 (1Gb ports)
48 * 48 ports = 2304 240 (10 Gb ports)
ports per expansion * 2 expansion blade
= 8 ports
8 ports + 40Gb (4 * 10GB) = 12 ports
12 ports per MXL * 2= 24 ports per
chassis
10 chassis * 24 ports= 240 ports.
1248 (10 Gb ports)
26 Leaf devices * 48 ports =
1248
From each leaf (S4810/
S4820-T) two 40G ports are
used as VLTi connections
and two 40G are used as
fabric links. The remaining
forty–eight 10G ports are
used as downlinks.
Type 1: 1 Gb ToR VLT Deployment
With a Type 1: 1 Gb ToR VLT Deployment fabric design, the S4810 spines connect to leaves (S60 or S55) at fixed 10 Gb.
The maximum number of spines is 2 and the maximum number of leaves is 44. Use this type for a ToR deployment that
requires 1 Gb downlinks and stacking. On S60 or S55 leaf switches, the leaves must the same type of switch.
