Figure 1: Ring and cascade topology for stack
In the case discussed here, we are using S4048 switch and stack groups 0 through 11 correspond to 10G
stack groups with four ports each. Stack groups 12 to 17 are one 40G port each.
1. Stack group 0 (ports 1,2,3, and 4)
2. Stack group 1 (ports 5,6,7, and 8)
3. Stack group 2 (ports 9,10,11 and 12)
4. Stack group 3 (ports 13,14,15 and 16)
5. Stack group 12 (port 49)
6. Stack group 14 (port 51)
7. Stack group 16 (port 53)
8. Stack group 17 (port 54)
9. Stack group 15 (port 52)
10. Stack group 13 (port 50)
By default, each unit has stack unit number of 1 that can be changed using the renumber command.
