- Why I did it
New SKU for MSN-4700 Platform i.e. Mellanox-SN4700-C128
Requirements:
* Breakout: Port 1-32: 4x100G
* Downlinks: 120 (1-30)
* Uplinks: 8 (31-32)
* Shared Headroom: Enabled
* Over Subscribe Ratio: 1:8
* Default Topology: T2
* Default Cable Length for T2: 1500m
* QoS params: The default ones defined in qos_config.j2 will be applied
* Small Packet Percentage: Used 50% for traditional buffer model Note: For dynamic model, the value defined in LOSSLESS_TRAFFIC_PATTERN|AZURE|small_packet_percentage is used
Additional Details:
Switch Type has to be programmed as SpineRouter through config_db.json in DEVICE_METADATA|localhost|type field for the buffer values & cable lengths defined in the buffers_defaults_t2.j2 to apply on the device
Cable Lengths Used for generating buffer_defaults_{t0,t1,t2}.j2 values
