Cisco Nexus 7000 Product Identification Scheme
N7K – C7010 – FAB – 1
1-4 = (N7K-) Nexus 7000 family and series identifier
5 = (C) – Chassis and Chassis-dependent modules
6-9 = Chassis model
10 – Dash
10 – 16 – Defines chassis- dependent modules
= (FAB) – Fabric modules
= (FAN) – Fans
= (S) – System bundle
N7 K – M1 32 XP – 12
In the above example,
- N7 stands for family name
- K stands for Series ID
- M1 stands for FE type. Gen
- 32 stands for ports
- XP stands for speed
- 1 stands for series of fabric
- 2 stands for number of fabric cards for full bandwidth; no redundancy
N7K-M132XP – 12 10Gigabit Interface Rate Modes
- Mode configurable on per-port-group basis:
Port groups consist of four contiguous odd or even interfaces (for examples, {1,3,5,7}. {2,4,6,8}, {9,11,13,15}. and so on)
- Shared mode
All four interfaces in the port group share 10 Gb bandwidth
- Dedicated mode
One interface gets 10 Gb bandwidth
Three other interfaces in the port group are disabled
Dedicated mode interfaces: 1, 2, 9, 10, 17, 18, 25, 26.
